Chemistry Paper 22 3rd Nov
Hypernova:
That was the only one that i can remember that i got wrong,
I made a stupid mistake somewhere.
I've been going over it again and again in my mind, but don't know where I messed up.
I'm impatiently waiting for the marking schemes to get out

Hey don't worry about it now.
You'll only harm yourself by thinking about it over and over again. you won't be able to change anything now. What's already happened cannot be changed. Just chill a bit and concentrate for the rest of your papers. ;)
I think i made some minor mistakes as well :(

aw dnt worry about it bro.. DK is right, thinking about it cannot change a bit of anything now isnt it. i know how tempting it is to go over the exam in ur head and remember what u got wrong, but whats the point. if it makes u feel better, i didnt manage to get the formula of CH4 nor the volume of the 2 gases. thats like 5 marks gone already. but it doesnt matter one bit because as long as i know i did well in the rest of my paper i feel im getting an A :) DK, which questions do you think u got wrong?

Hmm...........the two processes of cracking :-[
I was aware of only one process.
The last number as well.............hydrogen hallide. Am not sure about the answers. :-\
Hypernova:
In cracking, one process uses heat, and the other uses a catalyst...right?
The one using heat make a hard polymer, and the one using a catalyst makes a soft polymer like plastic bags.
X was I2 right...so the halide was HI
Did you guys get the same?
