Chemistry Paper 3 IGCSE Oct.Nov. 2013 Discussion

[MadaraYash]

Oh ! Thanks a lot ! I am really glad !
Hope its easy !! xD 32 is kind of easier than 33 i guess lol

 

[MadaraYash]

Lanocaster best of luck for your paper
And you too qasimnisar2121

well whats ur centre number and which city?

 

[johnsternater2000]

okay here goes,
equations for contact process, all acid base equations, half equations for electrolysis, the combustion of an alcohol, zinc extraction equations, this isn't really equations but know how to derive a monomer from a polymer like propene from polypropene (might seem rediculously easy but they put like polypheylethene or something like that in mine so learn it, Mine only tested on addition polymers for deriving a monomer.)
ALSO IMPORTANT, all those hydrogenation and hydration of alkenes and cracking etc general formulae.............. REMEMBER THEM

Oh okay..Thanks!!

Same to you MadaraYash
My school is in Mumbai too!

I mean i worked quite fast fearing that i won't finish the paper, but i completed almost all of my answers and there was still 20 minutes left!

That happens with me too! I usually finish with enough time to check the paper 2-3 times and 5 minutes remaining after that (English is an exception)

 

[Abdi majid]

HEhe, sure (i feel so rebel)

well there was a couple.
Overall the paper was on isotopes (like the first question) bonding, a little about zinc extraction (and the Electrolysis of zinc as well... but you do really need to study anything for that you just apply normal electrolysis stuff...) and organic (cracking, isomers, hydrolysis of proteins adn more i sorta forgot......... oh yeah and how to draw polymers i.e. in my paper there were two questions on polymer drawing), , only a tiny bit of moles (finding the maximium mass of a product given the mass of the reactent) and a tiny bit about electrolysis. In mine there were no electrochemical cells... There also was a six mark question on just describing the contact process (FREE MARKS!!!)

i also did variant 33 what was you answer for the mol question

Oh okay..Thanks!!

hmm... i have p32 too!! but guess what.. we both have it on exact same timings!! just 3 hours left! but.. i am in Saudi Arabia!

 

[johnsternater2000]

i also did variant 33 what was you answer for the mol question

not too sure i think 36.8 grams.....

Did u do paper 32 guys ?

 

[MadaraYash]

Nopee Gonna do in about 1 and a half hour ! Feeling nervous

Oh which school do you go to?

Did variant 2 today.Paper was slightly challenging.

 

[qasimnisar2121]

Did variant 2 today.Paper was slightly challenging.

Exactly!! i found it pretty lengthy!! rest was fine except 1 or 2 parts....... but i guess the real challenge was time!!

 

[Lanocaster]

Did variant 2 today.Paper was slightly challenging.

I found it quite easy, I'd rate it 8-9 on a scale of 10 (10=damn easy).
I was not sure about 1 answer, but rest I am pretty sure I'll score good

 

[Hamzeh S]

what did u guys get for the mole question last one ?

 

[Lanocaster]

So

what did u guys get for the mole question last one ?

mething like o.667

 

[Hamzeh S]

So
mething like o.667

i got 6.64 or smthn

 

[tonysingh]

I got 0.664 grams.

 

[Lanocaster]

I got 0.664 grams.

That's what I got

i got 6.64 or smthn

How'd you get that?
