Many students have fallen sleep during a class, this is a proven fact, but, do you think it has to do with the subject being boring? The teacher being boring? or the student is tired and hasn't a good sleep the night before? The solution for some teachers is to tell that student to go outside and go refresh his face with water so he can wake up, and it seems to work, but, is it really one of

Ok, time to practice the Acids Nomenclature, this will help you through your school exams, and remember, anything can be achieved with a little practice. Name these Acids with all 3 nomenclatures; remember to use the tricks we learned. EXAMPLE Name this Acid HClO4 Remember how to make Acid formulas? Now we just need to go backwards to figure out which oxidation number the metal

The energy of the light is part of your existence. Without it life wouldn’t have been able to grow, and if it suddenly ended, life would disappear. The relationship between the man and the Sun has always been filled with mystery and confusion. Since the men started to consider the sun a God, the explanations about the light and energy we get from it were variants, but we have always known how

Solar cells are capable of producing a reasonable amount of electric energy from solar light. This has stimulated the imagination of many creative people around the world. One of the most attractive uses for the photo electricity –electricity produced by light– are the vehicles powered by solar energy. So far, tests on airplanes, boats and cars have been performed with different results. A

The solar light is very important for the life on earth. It’s one of the most important world energy resources used by plants and seaweeds to transform the nutrients to grow. The oxygen we breathe is released in the process. The plants absorb water and minerals through the roots that end up in the leaves thanks to a network of small conducts. The leaves absorb Carbon dioxide from the air and,

This is an important concept you must know, it is studied in the firsts courses or High school and University, but still a very hard topic to understand. the hardest course about energy i took was Thermodynamics. Matter and Energy The entire Universe is formed by matter and energy. The matter is relatively easy to distinguish: wood, plastic, water or steal are different examples of

So in the end, in relation to the floatability of a body the most important thing is not the absolute density, but the relative density of the object and the fluid in which the object is immersed. For example, the wood is a dense object and heavy in the air, but it is not if its in the water, because the density of the water is bigger than the wood’s. This concept is used in many aspects of

As we already know, the floatability of an object depends of the hydrostatic push of the fluid in which it is immersed. Objects which density is lower or equal to the density of the fluid will float. Float in the water Sometimes you would wonder, why all those big ships made of steel can float in the water? Even though the iron and steel are like 8 times denser than water, a boat can

Everything I said about density and hydrostatic push is valid for all fluids, gas and liquid. Therefore it can also be applied to the air. The bodies immersed in air also experiment a push towards up that equals the weight of the displaced volume of air, but this push has a low value for objects with high density, as the human body for example, and its effects are not noticeable. This is not the

Today I'm gonna introduce a physical concept that is used a lot in Chemistry. Like some physical properties, this one is hard to explain; I never had a clear concept on college and only understood it correctly in university. Let’s use this example: What weights more, a pound of rocks or a pound of feathers?               &

The recommended format and the most used is the ANSI MSDS, but the OSHA (Occupational Safety and Health Administration) categories are the minimum and the legally enforceable. Most of MSDS are using the ANSI format but if you find an OSHA MSDS these is what you will find in it. Let’s use the MSDS of the ACETONE   Section I. Manufacturer's Name and Contact Information

The American National Standards Institute (ANSI) has a more detailed format for the MSDS, this one is the most common, I found a nice website where you can find pretty much the MSDS of any substance: MSDS DATA BASE Here i'll describe what kind of information you can find in these type of MSDS using the Benzene.

I know that once you are in a Lab, the first thing that comes to your mind is start mixing things and watch chemical reactions; I've been there but trust me, its important to know what type of chemicals you are dealing with in case something goes wrong. Every laboratory must keep the MSDS (Material Safety Data sheet) of every single one of the reagents they use. This sheet has all the

Another common and useful Glassware found on the lab is the Erlenmeyer Flask, why is it called this way?, this is thanks to its creator: Emil Erlenmeyer.

One of the main reasons I decided to study chemistry was the opportunity to be at a laboratory, experimenting with chemicals. But soon i realized that i wasn't going to do any real science for some months, until i had learnt all the basics for Laboratory Experiments, that is safety rules and everything about the Lab Materials.
