&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; line-height: 18.5467px;&quot;&gt;Las bombillas halógenas son bombillas incandescentes (las de toda la vida) a las que se añade un halógeno generalmente Iodo o Bromo y se cambia el vidrio de la ampolla por cuarzo que resiste mejor las altas temperaturas. En las bombillas tradicionales el wolframio se evapora yendo hacia las partes más frías de la bombilla donde tiende a depositarse&amp;nbsp;&lt;b&gt;ennegreciendola&lt;/b&gt;.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; line-height: 18.5467px;&quot;&gt;¿Entonces por qué no hay que manipularlas con los dedos? Por muy limpias que estén las manos siempre contienen&amp;nbsp;&lt;b&gt;grasa&lt;/b&gt;. La grasa al calentarse provoca una alteración química del material (&lt;b&gt;desvitrificación&lt;/b&gt;) llegando a fundir la bombilla. Además en los lugares donde está presente la grasa la temperatura aumenta, no se lleva a cabo el ciclo del halógeno por lo que no se puede regenerar el filamento y el wolframio comienza a ennegrecer la bombilla.&amp;nbsp;&lt;/span&gt;&lt;/div&gt;

Desde el punto de vista químico, se trata de un ácido débil que se puede indicar como HL. Al medir el pH de una disolución 0,05 M de este ácido, se obtiene un valor de 2,59. Calcula: a) La concentración de H&lt;sup&gt;+&lt;/sup&gt;&amp;nbsp;de la disolución. b) El valor de su constante de acidez. c) La concentración de OH&lt;sup&gt;−&lt;/sup&gt;&amp;nbsp;de la disolución.

&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; font-weight: normal;&quot;&gt;Hace más de diez años surgió en las redes sociales un mensaje que advertía sobre el uso inadecuado del papel de aluminio y hoy os hablo del tema en el blog aprovechando que hace unos días le llegó ese mismo mensaje a mi madre por whatsapp:&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; line-height: normal;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; font-weight: normal;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; line-height: normal; margin-bottom: 0.0001pt;&quot;&gt;
&lt;i&gt;&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; font-weight: normal;&quot;&gt;&quot;El papel de aluminio se utiliza ampliamente en los alimentos, pero en la mayoría de los casos se usa incorrectamente. Los usuarios tienden a poner la cara brillante hacia fuera, ya que deja el aspecto del plato más bonito.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/i&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; line-height: normal; margin-bottom: 0.0001pt;&quot;&gt;
&lt;i&gt;&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; font-weight: normal;&quot;&gt;El lado más brillante es así porque se hace un pulido del aluminio para crear una barrera y evitar el contacto directo del aluminio con los alimentos y, por lo tanto, su liberación a nuestra receta. Si no tendríamos que llamarla “tortilla de papas con aluminio”, porque el aluminio entrará como un verdugo invisible en el alimento &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/i&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; line-height: normal; margin-bottom: 0.0001pt;&quot;&gt;
&lt;i&gt;&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; font-weight: normal;&quot;&gt;Esta protección, el pulido, no está en ambos lados ya que es un proceso costoso que haría que la comercialización del aluminio fuera inviable.&amp;nbsp;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/i&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; line-height: normal; margin-bottom: 0.0001pt;&quot;&gt;
&lt;i&gt;&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; font-weight: normal;&quot;&gt;El&amp;nbsp;aluminio es altamente tóxico y es sin duda responsable de complicaciones generales en el funcionamiento de nuestro cuerpo y puede ser un factor de la enfermedad de Alzheimer, fomentando su aparición temprana&quot;.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/i&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; line-height: normal; margin-bottom: 0.0001pt;&quot;&gt;

&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; font-weight: normal;&quot;&gt;Son palabras de Ricardo Penna más conocido como Penninha un asesor gastronómico&amp;nbsp;portugués, pero este mensaje es fácil de desmentir remitiéndonos&amp;nbsp;al proceso de fabricación. Es tan sencillo como que en proceso de fabricación no hay etapa de pulido. Según los fabricantes ambas caras son aptas para su uso en alimentos.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; line-height: normal; margin-bottom: 0.0001pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; line-height: normal; margin-bottom: 0.0001pt;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; font-weight: normal;&quot;&gt;¿Entonces por qué hay una cara mate y otra brillante?&lt;/span&gt;&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt;&quot;&gt;&lt;span style=&quot;font-weight: normal;&quot;&gt;&amp;nbsp;Ya en la etapa final de la producción del aluminio, éste es tan fino que se teme se pueda romper y por lo tanto se duplica la lámina&amp;nbsp;para hacerla pasar por los rodillos. La cara que está en contacto con la otra lámina queda mate y por el contrario las caras expuestas a rodillos de acero quedan brillantes de forma casual. Se que es una idea preconcebida por muchos y muy extendida pero ambas caras son iguales. Os dejo el vídeo&amp;nbsp;que ilustra la explicación:&lt;/span&gt;&lt;b&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt;&quot;&gt;Si tuviéramos dos vasos uno con agua a 90ºC y otro con agua a 30ºC y los metiéramos al congelador ¿qué vaso se congelaría antes? Basándonos en nuestro sentido común la mayoría de nosotros no acertaríamos. Os presento el&lt;span class=&quot;apple-converted-space&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;b&gt;efecto Mpemba&lt;/b&gt;&lt;span class=&quot;apple-converted-space&quot;&gt;&amp;nbsp;&lt;/span&gt;y es que en determinadas situaciones el agua caliente se enfría a mayor velocidad que el agua fría. Recibe el nombre en honor a un heladero tanzano que llamó la atención sobre el efecto en 1969.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt;&quot;&gt;Lo primero aclarar que solo ocurre en determinadas circunstancias, si tenemos dos vasos a 20ºC y 10ºC el vaso con agua a menor temperatura congelará antes. Por lo tanto hay algunos requisitos para apreciar el efecto como es una diferencia de temperatura &amp;nbsp;y elevadas temperaturas.&lt;/span&gt;&lt;/div&gt;

Las capas de hielo que se forman en la parte superior del agua fría dificultan el intercambio de calor. En la escuela se enseña que la vida marina es posible en los polos gracias a la capa de hielo que se forma y que aísla la vida de las bajas temperaturas del exterior (sin olvidar el &amp;nbsp;que el hielo es menos denso que el agua &amp;nbsp;y flota).&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; line-height: 107%;&quot;&gt;Hoy toca rendir homenaje a Alfredo Moser un hombre nacido en
brasil que descubrió que al llenar una botella de plástico con lejía esta
funcionaba como una bombilla utilizando la refracción solar. Esta sencilla
lámpara precisa únicamente de una botella de plástico transparente, unas
cucharadas de lejía y cloro del utilizado en las piscinas para evitar que el
agua se enturbie de algas con el tiempo.&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13.0pt; line-height: 107%;&quot;&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt;&quot;&gt;¿Cómo se
le ocurrió la idea? En el año 2002 Alfredo tenía una conversación con su jefe
sobre una situación hipotética en la que necesitaban dar una señal de alarma
&amp;nbsp;en el barrio sin disponer de &amp;nbsp;luz ni cerillas &amp;nbsp;y es ahí cuando
su jefe sugiere llenar una botella de plástico con agua para usarla como lente
y quemar hierba seca. Y así fue como&amp;nbsp;Alfredo buscando una solución para
los continuos apagones eléctricos en su país los cuales no le permitían
trabajar en su taller recordó las palabras de su jefe y se puso a experimentar
con botellas de agua.&amp;nbsp;Según Alfredo y dependiendo de la intensidad solar
su invención puede ser equiparable a una bombilla de 40 a 60 W.&lt;b&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;margin-bottom: .0001pt; margin: 0cm; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify; text-indent: 35.4pt;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;verdana&amp;quot; , sans-serif; font-size: 13pt; line-height: 107%;&quot;&gt;

&lt;o:p&gt;&lt;/o:p&gt;

La implantación progresiva durante el año 2008 del método Moser en Brasil y
México dio años mas tarde a un proyecto llamado&amp;nbsp;&quot;un litro de
luz&quot;&amp;nbsp;desarrollado por estudiantes del MIT (Massachusetts Institute of
Technology) y por la fundación filipina&amp;nbsp;My shelter foundation.&lt;b&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;background-color: white; font-family: Arial, Helvetica, sans-serif; text-align: justify;&quot;&gt;COMO PREPARAR UNA SOLUCION 2 NORMAL DE NaCl , el volumen 1,450 ml de H2O.&lt;/span&gt;&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;background-color: white; font-family: Arial, Helvetica, sans-serif;&quot;&gt;Teniendo en cuenta la siguiente fórmula&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;background-color: white; font-family: Arial, Helvetica, sans-serif;&quot;&gt;N=M*v--&amp;gt;M=N/v Para el caso del NaCl la normalidad es igual a la molaridad porque la valencia es 1.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;background-color: white; font-family: Arial, Helvetica, sans-serif;&quot;&gt;Ahora utilizamos esta fórmula&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;background-color: white; font-family: Arial, Helvetica, sans-serif;&quot;&gt;M=n/V&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;background-color: white; font-family: Arial, Helvetica, sans-serif; line-height: 18.200000762939453px;&quot;&gt;Una aleación metálica consiste en una mezcla de 28% de estaño y 72% de hierro (porcentajes peso / peso), y la disolución sólida tiene una densidad 8.52 g/cm3. ¿Cuál es la masa de estaño expresada en gramos presente en un barra de 250 cm3 de esta aleación? te agradecere mucho﻿&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;background-color: white; font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;line-height: 18.200000762939453px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;span style=&quot;background-color: white; font-family: Arial, Helvetica, sans-serif; line-height: 18.200000762939453px;&quot;&gt;m(g)=v(cm3)*d(g/cm3)=250(cm3)*8,52(g/cm3)=2130g de barra de aleación Sn y Fe.&lt;/span&gt;&lt;br /&gt;

Si deciden desobedecer esta recomendación al menos háganlo en un sitio abierto por los vapores que se liberan.&lt;br /&gt;
&lt;br /&gt;
Se necesitará:&lt;br /&gt;
-Vaso de precipitados,&lt;br /&gt;
-azúcar&lt;br /&gt;
-varilla de vidrio&lt;br /&gt;
-agua&lt;br /&gt;
-ácido sulfúrico&lt;br /&gt;
&amp;nbsp;-guantes&lt;br /&gt;
-gafas.&lt;br /&gt;
&lt;br /&gt;
Hola amigos os traigo la reacción entre el ácido sulfúrico y el azúcar. El ácido sulfúrico deshidrata el azúcar para dar carbono.&lt;br /&gt;
&lt;br /&gt;
En primer lugar y de forma opcional se añade agua en un vaso de precipitados y añadimos azúcar. Removemos con la varilla y añadimos algo de ácido sulfúrico.&lt;br /&gt;
Si añadimos agua haremos que la reacción sea muy rápida, si lo que queremos es que nos de tiempo de apartarnos recomiendo que se haga sin agua.&lt;br /&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: 12pt; line-height: 18px;&quot;&gt;Científicos estadounidenses han identificado un compuesto que&amp;nbsp;&lt;b&gt;revierte&lt;/b&gt;&amp;nbsp;el&amp;nbsp;&lt;b&gt;síndrome de Down.&lt;/b&gt;&amp;nbsp;Los investigadores lo han utilizado con éxito en ratones recién nacidos.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: 12pt; line-height: 18px;&quot;&gt;El compuesto obtenido es una pequeña molécula de un proteína conocida como &#39;Sonic hedgehog&#39;. Al ser inyectado en el cerebro de los ratones recién nacidos con síndrome de Down, provocó un&amp;nbsp;&lt;b&gt;aumento notable del volumen del cerebelo atrofiado&lt;/b&gt;&amp;nbsp;hasta el tamaño normal, recuperando las capacidades de aprendizaje y la memoria de los roedores.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: 12pt; line-height: 18px;&quot;&gt;El síndrome de Down es un trastorno genético causado por la presencia de una copia extra del&amp;nbsp;&lt;b&gt;cromosoma 21&lt;/b&gt;. La mayoría de las personas con síndrome de Down tienen un cerebelo del 60% del tamaño habitual.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: 12pt; line-height: 18px;&quot;&gt;En las pruebas de comportamiento, los ratones tratados comenzaron a desarrollarse tan bien como los ratones sin dificultades de aprendizaje, dice uno de los autores del estudio, Roger Reeves, de la Escuela de Medicina de la Universidad John Hopkins en Baltimore.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: 12pt; line-height: 18px;&quot;&gt;Los científicos han advertido de que todavía no se ha demostrado que el uso del compuesto sea seguro para tratar a las personas con síndrome de Down, pero dicen que sus experimentos son prometedores para el desarrollo de fármacos similares.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

Hola amigos, coincidiendo con la vuelta a las clases y dedicado a todos aquellos estudiantes que empiezan las clases de química o para los más despistados como yo que necesitan saberse la tabla periódica os traigo una serie de truquillos para aprenderos la parte, que en mi opinión es la más difícil: metales de transición y transición interna.&lt;br /&gt;

&lt;span style=&quot;background-color: white;&quot;&gt;Los expertos estadounidenses lograron controlar a distancia el movimiento de las manos de un colega a través de señales enviadas por internet, usando grabaciones eléctricas del cerebro y una estimulación magnética. &quot;Internet permite conectar computadoras, pero ahora también puede conectar cerebros&quot;, afirmó Andrea Stocco, quien movió su dedo sobre un teclado a partir de una señal mandada por el cerebro de un colega que se encontraba en otra parte del campus universitario.&lt;br style=&quot;margin: 0px; outline: none; padding: 0px;&quot; /&gt;&amp;nbsp;&lt;/span&gt;&lt;br /&gt;

No obstante, afirman que el próximo desafío será lograr una conversación más directa y equitativa entre ambos cerebros, y no solamente mandar un mensaje de emisor a receptor.&lt;/span&gt;&lt;/div&gt;

En temperatura ambiente, la brea cae muy, muy lentamente formando una gota.&lt;/span&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;span style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot;&gt;Para ver la historia del experimento, nos tendremos que situar en los años 20 del siglo pasado, específicamente 1927. En la Universidad de Queensland, en Australia, el profesor Thomas Parnell les dijo a sus alumnos que iba a hacer un experimento para demostrar que existen sustancias que a simple vista pueden ser sólidas pero en realidad son fluídos muy viscosos y para esto puso un poco de brea en un embudo y dio un plazo de tres años para observar que había sucedido.&lt;/span&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;span style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot;&gt;Así que despues de tres años, ya en 1930, observaron que el sello del embudo se había roto y esto posibilitó que la brea fluyera y pudiera empezar a caer. En ocho años mas, ya en 1938 recién se formó una gota que cayó en diciembre de ese año y a partir de ese año hasta nuestros días, han caído en total 8 gotas.&amp;nbsp;&lt;/span&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;span style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot;&gt;Haciendo un recuento de las fechas en que cayeron las 8 gotas hasta estos dias, esto ha sido así: 1ra gota: diciembre 1938, 2da gota: febrero 1947, 3ra gota: abril 1954, 4ta gota: mayo 1962, 5ta gota: agosto 1970, 6ta gota: abril 1979, 7ma gota: julio 1988, 8va gota: noviembre 2000.&lt;/span&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;span style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px; font-style: italic;&quot;&gt;El experimento de la gota de brea&lt;/span&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhozZIMLplsO-dgxtQxEroje_Jpy-jb92YpxQPCfZD7mqpKEq3w5EcENDgk-AXN49HisocI066pynCSxgoEZywUNb-QQ-ON2dKw8F_1nG-c5o0wgr8nPsk765YJs0m2Gzo2gVoNAP7Nndc/s1600-h/02.jpg&quot; style=&quot;background-color: white; color: #0066cc; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px; text-decoration: none;&quot;&gt;&lt;img alt=&quot;&quot; border=&quot;0&quot; height=&quot;640&quot; id=&quot;BLOGGER_PHOTO_ID_5240559912894032370&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhozZIMLplsO-dgxtQxEroje_Jpy-jb92YpxQPCfZD7mqpKEq3w5EcENDgk-AXN49HisocI066pynCSxgoEZywUNb-QQ-ON2dKw8F_1nG-c5o0wgr8nPsk765YJs0m2Gzo2gVoNAP7Nndc/s640/02.jpg&quot; style=&quot;border: 0px; display: block; margin: 0px auto 10px; text-align: center;&quot; width=&quot;425&quot; /&gt;&lt;/a&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;span style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot;&gt;Como vemos, el experimento nació en una clase y se convirtió sin querer en el experimento mas largo de la historia. Según los datos obtenidos del experimento, se ha calculado que la brea es cien mil millones de veces mas viscosa que el agua, pero al no estar el experimento bajo un clima controlado, estos datos pudieran variar ante temperaturas cambiantes y se puede ver incluso una distancia de tiempo mayor entre la gota de 1988 y la gota del año 2000 y esto debido a la instalación del aire acondicionado en las instalaciones del lugar del experimento. En los últimos años se colocó una web cam para observar la caída de la gota ya que hasta el momento nadie la ha visto caer.&lt;/span&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;br style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot; /&gt;&lt;span style=&quot;background-color: white; font-family: Trebuchet, &#39;Trebuchet MS&#39;, Arial, sans-serif; font-size: 13px;&quot;&gt;El experimento esta inscrito como record en el libro de Records de Guinness y se espera que continue cien años mas.

Científicos de Caltech y otras universidades recibieron fondos estatales para desarrollar un modelo que replica el proceso de generación de energía de las plantas para aplicarlo a vehículos.&lt;/h2&gt;

&lt;span style=&quot;background-color: white;&quot;&gt;Imitando la forma en que las plantas convierten la luz solar y el dióxido de carbono del aire en energía y oxígeno, el Centro Conjunto de Fotosíntesis Artificial del Instituto de Tecnología de California busca superar a la naturaleza y frenar el calentamiento global.

&lt;span style=&quot;background-color: white;&quot;&gt;Este esfuerzo está respaldado por US$ 122 millones de fondos del Departamento de Energía de EE.UU. y reúne el talento de 120 científicos de Caltech, la Universidad de Stanford, la Universidad de California en Berkeley, Irvine y San Diego y el Laboratorio Lawrence Berkeley.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;background-color: white;&quot;&gt;Se trata de otra revolución de la industria automotriz mundial que se remonta al siglo XIX y se suma a los trenes motrices eléctricos, los vehículos que se manejan solos y los autos que se arriendan por hora.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;background-color: white;&quot;&gt;Hace unos pocos años, los autos totalmente eléctricos también parecían una fantasía.

&lt;div style=&quot;color: #333333; font-family: &#39;Lucida Sans&#39;, &#39;Lucida Grande&#39;, &#39;Lucida Sans Unicode&#39;, Verdana, Geneva, sans-serif; font-size: 14px; line-height: 22.390625px; margin-bottom: 1em; margin-top: 1em; outline: none !important; padding: 0px;&quot;&gt;
&lt;span style=&quot;background-color: white;&quot;&gt;Para revolucionar el combustible para transporte, Lewis tiene un plan de dos pasos. En realidad, de dos saltos.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #333333; font-family: &#39;Lucida Sans&#39;, &#39;Lucida Grande&#39;, &#39;Lucida Sans Unicode&#39;, Verdana, Geneva, sans-serif; font-size: 14px; line-height: 22.390625px; margin-bottom: 1em; margin-top: 1em; outline: none !important; padding: 0px;&quot;&gt;
&lt;span style=&quot;background-color: white;&quot;&gt;Primero, la coalición apunta a desarrollar un sistema para fabricar grandes cantidades de combustible de hidrógeno usando dispositivos de bajo costo similares a los paneles solares. El hidrógeno líquido o gaseoso, que puede ser la fuente de energía de los autos con celdas de combustible superlimpio, se necesita para las plantas químicas y las refinerías.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #333333; font-family: &#39;Lucida Sans&#39;, &#39;Lucida Grande&#39;, &#39;Lucida Sans Unicode&#39;, Verdana, Geneva, sans-serif; font-size: 14px; line-height: 22.390625px; margin-bottom: 1em; margin-top: 1em; outline: none !important; padding: 0px;&quot;&gt;
&lt;span style=&quot;background-color: white;&quot;&gt;Luego viene el segundo salto: aplicar esta misma investigación al sistema que puede combinar el combustible de hidrógeno con el dióxido de carbono del aire, tal como lo hace una planta, para producir combustibles líquidos que alimenten a los autos, los camiones pesados, los barcos o los aviones.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #333333; font-family: &#39;Lucida Sans&#39;, &#39;Lucida Grande&#39;, &#39;Lucida Sans Unicode&#39;, Verdana, Geneva, sans-serif; font-size: 14px; line-height: 22.390625px; margin-bottom: 1em; margin-top: 1em; outline: none !important; padding: 0px;&quot;&gt;
&lt;span style=&quot;background-color: white;&quot;&gt;No será fácil, rápido ni barato obtener la gasolina sintética y libre de carbono. Los laboratorios de investigación de todo el mundo buscan con sumo interés alternativas al petróleo. Algunos son esfuerzos privados; otros tienen financiamiento de gobiernos. Mientras que algunos tratan de elaborar combustible a partir de algas, maíz u otros cultivos, Lewis sostiene que esas soluciones requieren demasiada agua o tierra, que serán necesarias para la producción de alimentos.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #333333; font-family: &#39;Lucida Sans&#39;, &#39;Lucida Grande&#39;, &#39;Lucida Sans Unicode&#39;, Verdana, Geneva, sans-serif; font-size: 14px; line-height: 22.390625px; margin-bottom: 1em; margin-top: 1em; outline: none !important; padding: 0px;&quot;&gt;
&lt;span style=&quot;background-color: white;&quot;&gt;La urgencia por aumentar las fuentes de energía de bajo carbono se ha intensificado en tanto las condiciones meteorológicas extremas se suman a la preocupación de que los gases que atrapan el calor en la atmósfera estén haciendo de la Tierra un planeta menos hospitalario.&lt;/span&gt;&lt;/div&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
Investigadores de la universidad de california (UCLA) han
desarrollado un nuevo polímero para la creación de paneles solares (PSC), dicho
polímero absorbe la luz infrarroja y al tratarse de dos células es capaz de
absorber hasta el 80% de la radiación que atraviese la película. También es
capaz de absorber una pequeña parte&amp;nbsp; de
la luz visible.&lt;br /&gt;

&lt;div class=&quot;MsoNormal&quot;&gt;
La principal ventaja de dicho polímero es que puede ser
aplicado a pantallas de “smartphones”, escaparates, coches: sin comprometer la
capacidad de los usuarios para ver a través de su superficie&amp;nbsp; “permitiendo que generen energía de manera
autónoma”, según ha explicado el autor principal del estudio, Yang Yang.&lt;/div&gt;

Hola amigos quien de vosotros no conoce Los M&amp;amp;M’s (los Lacasitos americanos), yo mismo los compro a veces en la universidad y sí son irresistibles, de hecho, siempre le propongo a mi amigo Aranda un juego al que casi siempre pierdo: esconder uno y yo adivinar el color si acierto me lo puedo comer jajaja.&lt;br /&gt;
&lt;br /&gt;
Pues bien os traigo una curiosa historia acaecida en un pequeño pueblo de Francia:Ribeauville; Dichas&lt;strong&gt;&amp;nbsp;abejas están produciendo una miel de color verde y azul&lt;/strong&gt;. Por otro lado,&amp;nbsp;&lt;strong&gt;aún queda por determinar si la miel de colorines es apta para su ingesta&lt;/strong&gt;. De momento, los apicultores de Ribeauvillé están de acuerdo con los expertos que desaconsejan y alertan los peligros de su consumo: “El producto no es vendible. Esto no es miel”.Incluso podrían provocar que la miel de las abejas fuera de colores. Es al menos lo que sugieren los expertos que han descubierto miel de colores:&amp;nbsp;&lt;strong&gt;los insectos podrían haber comido unos desechos azucarados procedentes de una fábrica de M&amp;amp;m’s&lt;/strong&gt;.&lt;/div&gt;
&lt;h2 style=&quot;background-color: white; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 2.1em; line-height: 1.15; margin: 40px 0px 0px; padding: 0px;&quot;&gt;
Otras cosas que afectan a las abejas&lt;/h2&gt;
&lt;div&gt;

Las abejas, al comer, no sólo pueden cambiar el color de su miel. También pueden cambiar sus genes.&amp;nbsp;&lt;strong&gt;La epigenética está revelando que la alimentación incluso modifica nuestros genes&lt;/strong&gt;&amp;nbsp;y, en consecuencia, la herencia que les dejaremos a nuestros descendientes, pero en el caso de los seres humanos no es tan patente como en el de las abejas.&lt;/div&gt;
&lt;div style=&quot;background-color: white; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 23.765625px; margin-top: 20px;&quot;&gt;
Eso sucede porque las abejas&amp;nbsp;&lt;strong&gt;poseen una estructura genética idéntica&lt;/strong&gt;&amp;nbsp;y, durante su etapa como larvas, tienen el mismo aspecto.&lt;/div&gt;
&lt;div style=&quot;background-color: white; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 23.765625px; margin-top: 20px;&quot;&gt;
La mayoría de las larvas recibe como alimentación una mezcla de miel y polen. Las larvas, entonces, se transforman en estériles abejas obreras. Sin embargo, las larvas que son alimentadas con jalea real,&amp;nbsp;&lt;strong&gt;acaban convirtiéndose en fértiles abejas reinas&lt;/strong&gt;.&lt;/div&gt;
&lt;div style=&quot;background-color: white; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 23.765625px; margin-top: 20px;&quot;&gt;
Lo que sucede que es que el puré de miel activa un proceso de metilación que anula ciertos genes responsables del desarrollo y transforma a las larvas en abejas obreras.&lt;/div&gt;

Sólo en Estados Unidos,&amp;nbsp;&lt;strong&gt;las abejas polinizan cultivos por valor de 19.000 millones de dólares al año&lt;/strong&gt;. Sin ellas no existiría la agricultura y toda la cadena trófica se iría al garete.&lt;/div&gt;
&lt;div style=&quot;background-color: white; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 23.765625px; margin-top: 20px;&quot;&gt;
Por ejemplo, para polinizar una hectárea de manzanos son necesarias 80.000 abejas; y en una hectárea de manzanos produce 500.000 manzanas (700 manzanas por manzano). Imaginaos el poder que tiene este pequeño insecto, y la de veces que hemos deseado aplastarlo&amp;nbsp;&lt;strong&gt;si saber que su extinción comportaría, tal vez, la nuestra&lt;/strong&gt;.&lt;/div&gt;
&lt;div style=&quot;background-color: white; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 23.765625px; margin-top: 20px;&quot;&gt;
No les tengáis miedo, morir por la picadura de una abeja, aunque posible, es más improbable que hacerlo por el impacto de un meteorito o la fuerza desbordante de un tornado.&lt;/div&gt;

&lt;span style=&quot;background-color: white;&quot;&gt;Para que el dispositivo, bautizado como
CampStove, funcione, sólo se necesita un poco de madera (ramas, piñas),&lt;span style=&quot;border: none windowtext 1.0pt; mso-border-alt: none windowtext 0cm; padding: 0cm;&quot;&gt;&amp;nbsp;colocarla en un pequeño recipiente de hierro y&lt;/span&gt;&amp;nbsp;encender

&lt;span style=&quot;background-color: white;&quot;&gt;CampStove carga los dispositivos móviles a la
velocidad de un ordenador portátil, de manera que no es tan rápido como un
cargador tradicional. Sin embargo, Cedar asegura que &quot;esta es una
velocidad suficiente para la mayoría de los consumidores&quot;.&amp;nbsp;&amp;nbsp;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

desarrollado un modelo más grande llamado HomeStove. Según la Organización
Mundial de la Salud, 3.000 millones de personas en los países en desarrollo aún
cocinan con fuego. El ingeniero estadounidense desea comercializar el HomeStove
como una alternativa más segura, más limpia de esta actividad domestica que
ofrece también otra ventaja importante: genera electricidad para cargar el
celular, algo muy útil teniendo en cuenta que acerca de 5.000 millones de usuarios
de teléfonos móviles viven en países en desarrollo.&lt;/span&gt;&lt;span style=&quot;font-size: 13.5pt;&quot;&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

Atracción de pareja, camuflaje, emisión de señales de advertencia y comunicación son algunas de las aplicaciones que la bioluminiscencia tiene en la naturaleza. Ahora, los humanos también hemos hecho uso de la bioluminiscencia en algunas ocasiones. Por citar un ejemplo, mineros galeses utilizaban la piel seca de ciertos peces para contar con mínimas fuentes de luz dentro de las minas de carbón. Sin embargo, en el año 1986, un grupo de científicos creó una planta de tabaco brillante, modificada genéticamente para recibir a uno de los genes de la luciérnaga (Photinus pyralis). Desde entonces se ha estado barajando la posibilidad de reemplazar las luces en las calles con “árboles brillantes”, y un reciente proyecto en Kickstarter busca ir en esa dirección.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14px; line-height: 20px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

El proyecto “Glowing Plant” prácticamente explotó a través de toda la Web. La idea es que gracias a la contribución de aquellos interesados, Genome Compiler, compañía responsable de esta iniciativa, tenga la capacidad de crear y distribuir públicamente semillas de Arabidopsis thaliana con el gen de la luciferasa, de forma tal que la planta brille en la oscuridad. En un comienzo, el proyecto necesitaba de 65.000 dólares para enviar las semillas a aquellos que aporten 40 dólares o más, pero el dinero recaudado está a punto de pulverizar la barrera de los 300.000 dólares. En caso de superar los 400.000 dólares, la compañía extenderá el desarrollo para ofrecer lo mismo, pero con rosas.&lt;/div&gt;
&lt;/span&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14px; line-height: 20px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;b style=&quot;font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14px; line-height: 20px;&quot;&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;b&gt;«Es legal y ético»&lt;/b&gt;&lt;/div&gt;
&lt;/b&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14px; line-height: 20px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

Las primeras plantas serán sintetizadas en junio, aunque los primeros envíos de semillas se llevarán a cabo en mayo de 2014. Aún así, grupos como Friends of the Earth y Action on Erosion han protestado enérgicamente, solicitando a Kickstarter que retire el proyecto y a los responsables de “Glowing Plant” que detengan el envío de semillas. Los grupos califican al proyecto de “irresponsable”, pero Omri Amirav-Drory, el CEO de Genome Compiler, fue lapidario en su respuesta: “Es legal, es ético, es hermoso, es importante, y no vamos a detener lo que estamos haciendo”.&lt;/div&gt;
&lt;/span&gt;&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 14px; line-height: 20px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

Por ahora, las semillas sólo serán distribuidas en los Estados Unidos, debido a que ciertos aspectos legales y regulatorios pueden bloquear la entrada de las semillas a otros países. Quien ofreció su punto de vista es John Ward, profesor de biología sintética en la University College London. Aclaró que la mutación en la planta no representa ninguna amenaza, y no le otorga ninguna ventaja que pueda afectar a otras especies. Por lo tanto, mientras el producto sea legal, la discusión es principalmente filosófica. ¿Estamos listos para tener plantas brillantes en casa?&lt;/div&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
Cuando mantenemos mucho tiempo abierto el frigorífico el aire frío se escapa por la parte inferior ya que es algo más denso por otro lado el aire caliente entra por la parte superior.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Todo frigorífico queda hermético una vez que se cierra debido a unas juntas y es entonces cuando ese aire caliente recién entrado comienza a enfriarse, y por lo tanto ocupa menos volumen. Se produce entonces una especie de vacío en el interior y es el responsable de la fuerza extra para abrirla y del típico sonido al abrirlo &quot;pop&quot; como si de un bote de conservas se tratara.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;span style=&quot;background-color: white;&quot;&gt;&lt;strong&gt;El ochoó (Hura crepitans),&lt;/strong&gt;&amp;nbsp;también llamado solimán, es un&amp;nbsp;&lt;strong&gt;árbol venenoso&lt;/strong&gt;&amp;nbsp;que se encuentra sobre todo en las zonas intertropicales del continente americano, especialmente en las cuencas del Orinoco y el Amazonas. Resulta&lt;strong&gt;&amp;nbsp;venenoso&lt;/strong&gt;&amp;nbsp;para personas y peces (el látex venenoso es útil para pescarlos, pues les atonta), pero no para muchos monos y aves que se alimentan de sus frutos.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;background-color: white;&quot;&gt;Su corteza se encuentra cubierta de numerosas&amp;nbsp;&lt;strong&gt;espinas&lt;/strong&gt;, al igual que sus frutos. Éstos maduran durante la temporada de lluvia y, al mojarse,&amp;nbsp;&lt;strong&gt;estallan produciendo un fuerte ruido&lt;/strong&gt;. El estallido hace que las semillas salgan disparadas a grandes distancias, incrementando la zona de difusión.&lt;/span&gt;&lt;/div&gt;

Hola a todos, estoy preparando los materiales necesarios para realizar termita y me gustaría compartir con ustedes como lo hago. Hoy aprenderemos como sintetizar nuestro propio óxido de hierro y aluminio para poder usarlo en nuestra termita o cualquier otra mezcla pirotécnicas.&lt;/div&gt;
&lt;div class=&quot;&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;span style=&quot;color: red;&quot;&gt;NO ME HAGO RESPONSABLE DE LOS DAÑOS SUFRIDOS. SI LO&amp;nbsp;HACÉIS&amp;nbsp;SERÁ VUESTRO PROPIA RESPONSABILIDAD.&lt;/span&gt;&lt;br /&gt;

Los reactivos normalmente se pulverizan y mezclan con un aglomerante para mantener el material sólido y prevenir su separación.&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;

Pues si he entendido bien esta será la reacción:&lt;/div&gt;

En la cual obtendremos &lt;b&gt;hierro&lt;/b&gt; metálico al rojo vivo a unos&lt;b&gt;&amp;nbsp;increíbles&lt;/b&gt;&amp;nbsp;2200-2500ºC.&lt;br /&gt;
&lt;div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Para que esta reacción funcione los reactivos tienen que estar finamente divididos, es decir, pulverizados.&amp;nbsp;&lt;/div&gt;

&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Vamos a ello, empezaré explicando como sintetizar el óxido de hierro.&lt;/div&gt;

&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
-Salfumant ( también llamada aguafuerte)&lt;br /&gt;
-un adaptador de corriente ac-dc cuanta más intensidad mejor&lt;br /&gt;
- 2 electrodos de hierro&lt;br /&gt;
-agua&lt;br /&gt;
-1 cucharada de sal&lt;br /&gt;
-varilla para agitar&lt;br /&gt;
-recipiente donde hacer electrolisis&lt;br /&gt;
-filtros de café&lt;br /&gt;
-cinta aislante&lt;br /&gt;
-cuchillo&lt;br /&gt;
-botella de plástico donde filtrar&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;color: red;&quot;&gt;PRECAUCIONES&lt;/span&gt;&lt;br /&gt;
Riesgo eléctrico&lt;br /&gt;
Usar guantes de plástico&lt;br /&gt;
No manejar electrodos conectados&lt;br /&gt;
No acercarse yendo descalzo&lt;br /&gt;
Hacer en un sitio aireado&lt;br /&gt;
No acercar fuego&lt;br /&gt;
Procedimiento: En este video os explico paso a paso todo el proceso desde fabricar los electrodos y como conectarlos hasta el resultado final del óxido de hierro.&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;iframe allowfullscreen=&#39;allowfullscreen&#39; webkitallowfullscreen=&#39;webkitallowfullscreen&#39; mozallowfullscreen=&#39;mozallowfullscreen&#39; width=&#39;320&#39; height=&#39;266&#39; src=&#39;https://www.youtube.com/embed/7wbW71EXa5g?feature=player_embedded&#39; frameborder=&#39;0&#39;&gt;&lt;/iframe&gt;&lt;br /&gt;
&lt;span id=&quot;goog_841333751&quot;&gt;&lt;/span&gt;&lt;span id=&quot;goog_841333752&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
En el recipiente de plástico añadir agua y una cucharada de sal, de esta forma conseguiremos que la electricidad se transmita bien por el agua.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Metemos los electrodos conectados al adaptador de corriente y conectamos a la luz; una vez pasadas unas horas filtramos la disolución utilizando dos filtros de café.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Hay que dejar que se filtre bien y después debemos secar, hay quien prefiere meter gran cantidad de filtros en el horno, yo lo que hago es colocarlo encima de radiadores ya que de esa forma en un par de días lo tenemos listo. Toda la explicación esta en el&amp;nbsp;vídeo.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Y hasta aquí de una forma sencilla y barata la síntesis del óxido de hierro solo nos quedaría pulverizarlo.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
PROXIMAMENTE tratamiento del aluminio&lt;/div&gt;
