[nafiz6]

Its been more than 24 hours since chemistry exam.. so am i allowed to ask about questions that was on Chemistry Paper 1, May 2013?

[NotAbod]

Yes, you're allowed to do that.

[nafiz6]

so, there was this question on chemistry.. they asked what type of reaction is "CaO + SiO₂ --> CaSiO₃"
I wrote neutralization, since its a reaction between an acid and a base/alkali. Is it correct?

Yes. Since metal oxides are basic and non metal oxides are acidic, this is an acid base reaction or neutralisation.

[nafiz6]

Awesome! Thanks!   
There was another question about halogens.. they gave the colors and physical state in room temp. for chlorine, bromine and iodine, and then asked: what would the color of Astatine be compared to Iodine?
I wrote : Astatine is darker than iodine.. am I right?

[NotAbod]

yes. It would have been even better if you mentioned that Astatine is black. But, I think what you wrote is fine.

[nafiz6]

Great! Hope they give marks for that.. Thanks again!
I feel kind'a relieved now!  Not sure about some experimental questions.. bt still my exam was great!!

[nafiz6]

Anyone gave further puremaths paper 1???

[ozzyd]

[neo]

i agree - lots of tough questions. Lets discuss it tomorrow

[shaazfm]

hows was pure maths paper 1??

[sukju596]

Biology was actually easier than what i thought it would be like, however English B.... I didnt like it at all.. not at all! Pure maths was very easy except question 9

[nafiz6]

puremaths paper 1 was awesome!! but i screwed up in a few parts x( ...since they give marks for methods, i'm expecting 90 up! 
By the way, which one was no. 9 again? the triangular prism? O.o
