Okay, er. I'm so shy?
The "I (hearts) 204" tee, is Kranji Sec 3A's tee design, aapparently, many people in Kranji 3A is very, as in VERY unhappy with it.
One of them came to tell me lah.
So, er. I guess I'll be designing one? Try to make the tee unisexual bah. Since it's a class tee, everyone should have to same design.

Uh, i ask you all ah, the Compunds worksheet right, what is the answers? I know a little 临时抱佛脚 lah. ;O For those who don't know know Chinese, 临时抱佛脚 is last minute hug God's leg? I guess? LOL.
-JANE :D
PAGE 56 . FOR CHEMISTRY .
THANKS TO MS DING .
I NO NEED TO DO ALL THE SCANNING ...
PAISEH =-0
MAKE SURE ALL OF U , UNGRATEFUL BRATS + UNGRATEFUL LADS ,
THANK MS DING FOR TYPING OUT ALL THE ANSWERS 2MR .
IF NOT I SLAP , CHOP , SLAUGHTER + KILL YOU ALL .
I HEREBY THANK MS DING . THANKSSSS !!! XD
obivously ,
from your violent chairgal .
Good luck!
Can we trouble Kimberly to post pg. 56 for us? =)
Periodic Table will be given to you in the common test.
Study hard and all the best!!!
Revision Questions Pg. 60 to 64
Pg. 60
1. B 2. D 3. B 4. C 5. D
Pg. 61
1a) Sugar : Constituents are combined during chemical reactions in fixed proportions by mass;
Sugar solution : Constituents do not combine in a fixed proportion and do not have to go
through chemical reactions to form sugar solution.
b) Little / no energy is exchanged with surroundings during its formation;
Constituents can be separated by physical methods;
Mixture has the properties of its constituents.
c) Simple Distillation
2. - Add water to the gardening mixture and stir.
- Wait for some time to let the mixture settle.
- The sawdust will float on the surface of the water and it can be removed and dried.
- The remaining mixture can be filtered. Calcium carbonate will remain as the residue.
- The potassium nitrate solution is the filtrate.
- The filtrate is evaporated to remove the water. Potassium nitrate is left behind as the
residue.
3a) Simple distillation
b) A - Condenser
B - Outlet for water
C - Inlet for water
c) No. The boiling point of water is 100 degree celsius.
d) D - distillate; Liquid - alcohol
4a) Elements : Nitrogen, oxygen, argon, neon, krypton
Compounds : Carbon dioxide, water
b) The constituents of air do not combine in fixed proportions.
c) Fractional distillation of liquid air is used. The difference in the boiling points of the constituents of liquid air is used to separate them.
5a) A solvent (eg. water / alcohol) is used. The food dyes, together with the solvent, will move up the filter paper but a different rates because some of the dyes move faster than others.
The dyes that hold on to th surface of the filter paper move solwer. The different dyes are thus spread out and separated into different components on the paper.
b) B, C, D
c) Yes. There is a matching spot of food dye C and the food colouring on the chromatogram.
Revision Questions Pg. 52 to 55
Pg. 52
1. A 2. A 3. C 4. D 5. B
Pg. 53
2a) Compound; It is broken down into simpler substances when heated.
b) Carbon dioxide; it is a compound of carbon and oxygen.
c) Copper oxide: Black; solid at room temperature
Copper : Reddish brown, shiny solid
Oxygen : Colourless; Gas at room temperature
3ai) Copper + chlorine --> Copper chloride
Or
Nitrogen + oxygen --> Nitrogen oxide
ii) Nitrogen oxide + oxygen --> Nitrogen dioxide
iii) Ammonia + Hydrogen chloride --> Ammonium chloride
b) Nitrogen oxide / nitrogen dioxide - nitrogen, oxygen
Ammonia - nitrogen, hydrogen
Hydrogen chloride - hydrogen, chlorine
Ammonium chloride - nitrogen, hydrogen, chlorine
Copper chloride - Copper, chlorine
c) All of the above in (b).
4a) Metal
b) It can used as an electrical wire.
c) It is a compound as it is formed from 2 elements in a chemical reaction.
5. The white solid is a compound because it breaks down into simpler substances when heated. However, we cannot conclude that the colourless liquid is an element because it could have been broken down into simpler substances by other chemical methods, for example, by passing an electric current through it.
Compounds Pg. 50, 51
Pg. 50
1. Metals - Cadmium, Titanium, Plutonium
Non-metals - Xenon, Astatine, Bromine
Sand - Silicon, oxygen
Iron sulphide - Iron, sulphur
Water - Hydrogen, oxygen
Glucose - Hydrogen, oxygen, carbon
Carbon dioxide - carbon, oxygen
Sodium chloride - sodium, chlorine
2a) F. Compounds are made up of 2 or more elements chemically combined.
b) F. Compounds are made up of elements which have been chemically combined.
c) F. The constituent elements of a compound may be metals and / or non-metals (not either / or).
Pg. 51
1. Property 1 : The properties of a compound are different from the properties of its constituent elements. For example, at room temperature, mercuric oxide is a red solid while mercury is a silvery liquid metal and oxygen is a colourless gas.
Property 2 : The constituents of a compound can only be separated by chemical methods. Mercuric oxide is broken down into mercury and oxygen when it is heated.
2a) The formation of compounds usually involves an exchange of energy with the suroundings.
bi) 56 + 32 = 88g of iron sulphide.
264/88 = 3 times
mass of iron present in 264g of iron sulphide = 88 x 3 = 168g
mass of sulphur present in 264g of iron sulphide = 32 x 3 = 96g
ii) if 56g of iron is mixed with 50g of sulphur and heated, only 32g of sulphur will react.
(remember 56g iron : 32g of sulphur)
Sulphur : 50g - 32g (reacted) = 18g (left behind)
Mass of iron sulphide formed = 56g iron + 32g sulphur = 88g
Answers to Chemistry WB Answers! Pg. 48, 49
Chapter 5 - Elements and Compounds
Pg. 48
1. Sulphur
- Dull appearance
- Brittle, not malleable or ductile
- Relatively low melting and boiling points
- Poor conductor of heat and electricity
- Relatively low density
Zinc
- Shiny appearance
- Malleable and ductile
- High melting and boiling points
- Good conductor of heat and electricity
- High density
2(a) The properties of the elements change gradually from metallic to non-metallic properties.
(b) Sodium, Magnesium, Aluminium
(c) Chlorine and argon. They are in the last 2 groups of the periodic table and the last 2 groups usually consist of non-metallic elements with low melting and boiling points.
Pg. 49
1.
Electrical wire - Metal : Good conductor of electricity
Frying pan - Metal : Good conductor of heat
Airship - Non-metal : Non-metals have low densities
Oven interior - Metal : High melting points
2a) Sodium is a reactive metal which reacts vigourously with water but aluminium does not.
b) Mercury has a low melting point and is a liquid at room temperature. Silver has a high melting point and is a solid at room temperature.

Monday, February 2, 2009
im posting just as a reminder~
i..or we hav decided not to celebrate for birthdays anymore..
not once term..
not once semester..
not once year..
but not really celebrating..
but its not finalized yet.
our plan is to:
-we will make cards for 41 of us(including ms ding)
-then when ppl's birthday are near..ppl who want to write their wishes write. those who dont..suit yourself.
-then we giv to that person!
plz comment on this as we need ideas.
we need $$ for your tee and outing/chalet
if you want celebrations...
we hav to increase your classfund
we either no celebration...no tee...or no outing/chalet.
choose plz.
those who did not see it..
too bad.
choice decision is to be made at classblog~~~
ty:)
-JingYi
Ermms,, HELLO 204(:
Eh..
Peoples,, i think we need to hand in more class funds?
We have to contribute together for the class tee and class outing..
Till now,, we have around $90+++ left in our class funds.
Its either we now slowly slowly month by month pay or when the time comes for class tee and class outing,, you all have to fork out all the money at once.
I think i'll leave it up to the treasurers to make the decision barhs.
Or vote/poll again?
:DDD
Reflect your wants on the tagboard(:
PEOPLES,, PLEASE MAKE AN EFFORT TO SAVE THE WORLD.
ANY UNWANTED PLASTIC BOTTLES,, PLEASE PLEASE GIVE IT TO JANE OR ME.
HAVE MORE INITIATIVE,, DONT MAKE US GO AROUND AND US FOR IT EVERYDAY?
although we like doing it~
THIS IS PART OF A GUIDES MOVEMENT,, TO SAVE THE WORLD.
WE WILL RECYCLE THE PLASTICS(:
