JOM BINCANG : SALTS

noreply@blogger.com (cikgu andromeda) — Sat, 19 Nov 2011 12:32:00 +0000

Pelajar saya selalu risau jika soalan topik SALTS...saya pun risau juga jika calon SPM pun masih tidak boleh menjawab soalan ini. Saya sediakan satu contoh soalan berkaitan topik ini yang kerap kali keluar dalam item soalan kertas 2.

Berdasarkan soalan ini, kita dapat lihat pemerhatian (observation) bagi setia proses yang dijalankan.

Proses 1 : menunjukkan Serbuk Hitam X di masukkan ke dalam larutan Asid hidroklorik.
Process 1 : shows Black powder X is added into Hydrochloric acid solution.

Dalam analisis sifat fizikal bahan kimia - serbuk yang berwarna hitam yang digunakan adalah Kuprum oksida (Copper oxide). Proses 1 adalah proses peneutralan (neutralisation) di antara Kuprum oksida dan asid hidroklorik. Hasil daripada peneutralan ini, CuO akan bertindakbalas dengan HCl untuk menghasil CuCl2 , Larutan Kuprum Klorida yang berwarna biru. Larutan biru Y (blue solution Y) adalah kuprum klorida (copper chloride).

How ? Bagaimana reaction ini berlaku?
"CuO mengion dalam asid. CuO ionise in acid, Copper ion dan Oxide ion move freely in solution. Copper ion attract to chloride ion in solution and formed CuCl2. Copper ion less electropositive than hydrogen ion, so copper easily attract to Chloride ion."

EXPERIMENT : EMPIRICAL FORMULA (SPOT)

noreply@blogger.com (cikgu andromeda) — Fri, 28 Oct 2011 15:30:00 +0000

Empirical Formula (Formula Empirik)
Formula show simplest ratio of atoms of each element in the chemical compound.
Formula yang menunjukkan nisbah terkecil atom bagi setiap element di dalam sebatian kimia.

Tips SPM : Calon mesti tahu definisi 'empirical formula'.

ANALISIS SOALAN SPM (2003-2010)

STRUCTURE QUESTION

SPM 2003 /PAPER 2/ QUESTION 1

Experiment to determine the empirical formula of magnesium oxide.

SPM 2007 /PAPER 2/ QUESTION 3

Experiment to determine the empirical formula of two compounds by different methods.

SPM 2009 /PAPER 2/ QUESTION 3

Experiment to determine the empirical formula of copper oxide

SPM 2004/ PAPER3/ QUESTION 1

Experiment to determine the empirical formula of magnesium oxide.

ESSAY QUESTION.

SPM 2010 / PAPER2/ QUESTION 7

Determine the empirical formula and molecular formula of hydrocarbon
CALON MESTI TAHU!!

To determine empirical formula of compounds - two methods used. (For SPM)

#1 - Heat metal in crucible and lids - More reactive metal than hydrogen

#2 - Heat metal oxide in excess hydrogen gas in combustion tube and porcelain dish

Precaution in both experiment
In Method 1 (M1) :
During heating lid opened a while to allow excess oxygen from the air reacts with metal
Lid closed quickly to prevent white fume/solid escape to the surrounding.
This precaution is important : to get accurate value of product after heating.

ISOTOPES (SPOT)

noreply@blogger.com (cikgu andromeda) — Fri, 28 Oct 2011 06:58:00 +0000

ISOTOPES : Atoms of an element has same proton number but different nucleon number.

Fact #1 Isotopes mempunyai nucleon number yang berbeza tetapi proton number tetap sama.
Fact #2 Elements yang sama sudah semestinya number of proton yang sama
Fact #3 Nucleon number = number of proton + number of neutron

when nucleon number different (same elements) = number of neutron different

example : carbon-12 and carbon-14

Name of element : CARBON
Proton number    : 6

Nucleon number Carbon-12 = 12
Number of neutron Carbon-12 = 12 - 6    = 6

Nucleon number Carbon-14 = 14
Number of neutron Carbon-14 = 14 - 6    = 8

Conclusion : Isotopes of elements has different number of neutron and nucleon number but same number of protons.

USES OF ISOTOPES

Carbon-14 : Archaeological Dating
This method called radiocarbon dating.
Remembering that the half-life of carbon-14 is 5700 years, then after 5700 years half as much carbon-14 remains within the organism.

Cobalt-60 : to kill cancer cells without surgery

Gamma rays of cobalt-60 are used to kill cancer cells without surgery in patients. This treatment is known as radiotherapy.

Iodine-131 : to investigate the thyroid glands by measuring the uptake of iodine-131.

This tracing method is also used to investigate the thyroid glands by
measuring the uptake of iodine-131.

Phosporus-32 : The metabolism of phosphorus by plants can be studied using phosphate
fertilisers that contain phosphorus-32.

A solution of phosphate, containing radioactive phosphorus-32, is injected into the root system of a plant. Since phosphorus-32 behaves identically to that of phosphorus-31, the more common and non-radioactive form of the element, it is used by the plant in the same way. A Geiger counter is then used to detect the movement of the radioactive phosphorus-32 throughout the plant.

Sodium-24 : to detect leakage of underground pipes.


Used to locate leaks in industrial pipelines, and in oil well studies.

LAWAK CHEMIST : H2O, water poisonous?

noreply@blogger.com (cikgu andromeda) — Fri, 28 Oct 2011 03:03:00 +0000

p/s : Sebenarnya , dia salah order , 1st chemist order H2O....yang kedua order H2O jugak tapi jadi H2O2 hydrogen peroxide is poisonous!!

KINETIC THEORY

noreply@blogger.com (cikgu andromeda) — Wed, 26 Oct 2011 12:43:00 +0000

Kinetic theory adalah teori yang menjelaskan keadaan suatu zarah(particles) samada atom, molecule atau ions pada satu-satu situasi.

Definition : theory that explains the physical properties of matter in terms of the motions of its constituent particles.

Contoh :

Naphthalene : at room temperature, naphthalene as solid molecule.
Room temperature=situation Solid=physical state , Molecule=particles

Secara tidak langsung kita akan mengetahui "particle arrangement", "energy content" dan "movement" bagi naphthalene.

HOW?

Particle arrangement of solid naphthalene are closely packed and orderly arranged.
as we know naphthalene is solid particles, so solid particles are arranged in closely packed and orderly.

"Describe in terms of states of matter, particle arrangements and changes in energy."

Bila soalan kata describe....kena la berpandukan apa yang diberi dalam diagram..."

Perkara pertama bincangkan dulu tentang masa dari t0 hingga t1...(apa yang berlaku pada masa ni)

Jika dilihat daripada graf...(constant graf) ia menunjukkan "boiling point" iaitu perubahan fizikal dari cecari ke gas. ( physical state : liquid to gas)

bermakna kita tahu pada t0....
physical state of matter adalah = liquid....

heating process yang berlaku, menyebabkan haba dibekalkan kepada bahan tersebut - bahan tersebut menyerap haba yang dibekalkan

pada t0 - t1
kinetic energy bertambah (semasa penyerapan haba)

kinetic energy yang terdapat dalam particles bahan tersebut menunjukkan particles memiliki ENERGY yang banyak untuk bergerak (move)

pada t0 - t1
particle arrangement close each other tetapi ada yang berjauhan disebabkan particles boleh bergerak, so the particles arrangement not orderly...

Seterusnya pada t1-t2 (fasa boiling point : liquid turn to gas)

pada masa kedua-dua bentuk fizikal wujud....liquid sedikit demi sedikit berubah menjadi gases

heat energy terus dibekalkan semasa pemanasan(heating process)....pada masa ini suhu tidak meningkat...haba yang dibekalkan-diserap(absrobed) oleh bahan digunakan untuk mengatasi daya tarikan di antara particles liquid.

ini menunjukkan kinetic energy tidak berubah....(haba diserap dan digunakan)

pada t1-t2, particle liquid telah berubah menjadi gas....sehingga pada t2 kesemuanya bertukar menjadi gas

some particle move far apart ...some particles close each other. particle arrangement not orderly.

pada t2 - t3 : tiada lagi perubahan fizikal yang berlaku...semua nya dah jadi gas...

physical states: all particles is in gaseous state

haba yang dibekalkan diserap oleh particles dan digunakan untuk bergerak lebih bebas...suhu bahan meningkat

kinetic energy particles meningkat apabila menyerap haba yang dibekalkan

the particle move freely and collide each other, it particles is not orederly arranged..

Combustion 0.202 g of a sample of organic compound containing elements carbon, hydrogen and oxygen to produce carbon dioxide 0.361 g and 0.147 g of water. If the relative molecular mass is 148, determine the molecular formula.

ANSWER:

mass of carbon in carbon dioxide = 12 x 0.361 / 44 = 0.0984 g
mass of hydrogen in water = 2 x 0.147 / 18 = 0.0163 g
mass of oxygen in compound = 0.202 - (0.0984 + 0.0163) = 0.0873 g

	Carbon, C	Hydrogen , H	Oxygen , O
Mass (g)	0.0984	0.0163	0.0873
Number of mole (mol)	0.0082	0.0163	0.0055
Mole ratio	0.0082/0.055 = 1.5	0.0163/0.0055 = 3	0.0055/0.0055 = 1
Simplest ratio	3	6	2
Empirical formula	C₃H₆O₂

Molecular formula =
(C₃H₆O₂)n = 148
3(12) + 6(1) + 2(16) = 148
74n = 148
n = 2

molecular formula = C₆H₁₂O₄
