In the first equation there were 3 moles, then in the second equation there was 1 mole, so that's 4 moles altogether produced from 1 mole of methane.
what did everyone draw for the question where it asks how you would collect nitrogen dioxide?
Ooft for the titanium one I put that although it's always decaying, it's also always being formed. (?!) And I wanted to draw a condenser type thing for the nitrogen dioxide, but really didn't have a clue what one looked like!
Can't say man, just hope the pass mark is relatively low, if you get around 30/40 in the first bit and 40 out of 60 in the second you can be assured an A.
did a fair amount. but id never done a past paper under timed conditions so that probs didnt help lol! wot u think the pass for an A is and wot is it usually for chemistry?
Well last year it was 78% for an A which is abit crazy, I haven't done last years Chem so I can't really say If this years' pass marks would be.
I studied 'til about 3.30am last night. I'll be disappointed if I don't get an A. i'm predicted an A.
I don't wanna predict. It either means dreams of medicine out the window, or tempting fate to 5 fails.
I did 2006 paper, and found todays paper easier, but most people said 2006 was easier so the A cut-off will probably be lower.
I had done most of those mulitple choice before.. they always repeat them! And it is Z for that multiple choice one, it has been in two papers before!
