    Horrible paper :/ all through lessons i've been quite good at the rates, acids, Kc, all of the maths parts, so I pretty much ignored those in my revision and have done three solid days of transition metals as I hate those and could never remember the reactions or colours, but then hardly any of that came up! and i can't remember once being asked for a colour so was a complete fail. I actually quite like the 2,2'-bipy question lol :P doesn't mean I got it right though. Really hope I didn't do as badly as I think I did because even if the grade boundaries are as low as they usually are, I didn't get higher than a D maximum, but I need a B, preferably an A for University

    Sorry for the long post!

    720 for the value of Kc?
    yeah me too, except im not sure what the right answer is... :/

    Yes!
    That monomer unit question was a bit random, no?
    And did you just have to find the difference in the half cell voltages for that one mark for Ecell? I did that, but i'm not sure because one produced 1 electron, the other took 2

    So random!
    You just had to take one from the other, electrode potentials are not dependent on the amount of electrons produced. That's what my revision guide says anyway :P

    i thought the biology was a piece of piss compared to this. This chem paper was the hardest ever.
    agree. some people walked out of my school crying after the chem this afternoon.

    I thik i got the same too, just the Magic Tang question and some ionic equations caught me out.
    Omg similar to me. Some ionic equations were annoying (especially the CaOH and acid one, couldn't balance for the H20 so added a H2) and the electrolyte producing O2 and H2 was dodgy too. Although I think I blagged the Magic Tang by saying how its not just about pH but also the taste of the acid and about making a conjugate base and acid and using ph=pka + log (A-/HA) to get a ratio (even though I used lactic acid cos I thought it had to one from the table). I think I choked the polymer question too (started drawing it as the invigilators started collecting papers) and only put half the cycolamine thing linking the monomers...

    Was there an actual method to working out which acid to use for the 'magic tang'? Because i said that all the acids would work so i just picked lactic acid and went with it :/ And i got a 1:2 ratio of salt:acid

    I got it in the 700's aswell, can't remember exactly but I think the 45 would come from if you deduced BR2 as second order and 700's if you got it as first order? I could be wrong though

    that sounds ok , I used acetic acid and got 16:1

    A girl waqs crying in my college I swear we got the worst questions all in one paper - most haven't even come up at all in the past papers - and i evern did a couple legacy ones

    damn you Q at the end and buffer Q with only a PH and Pka value!!!!

    Could you get your chemistry teacher to do the exam paper and then put his answers online. Atleast it will give us an idea of how we done.

    Hmm, I feel slightly screwed over...

    What's this bull**** about magic tang?!

    Also, was anyone actually able to draw out that polymer??
