What u think of it really cause I'm in that stage that anyone goes through when you replay the exam and guess your marks?
Which parts do you think where the hardest?
If anyone knows where I can get the 2003 june exam papers I would so Very VERY pleased.
didn't think i did very well on it thought - left out some really obvious stuff like ethanol being volatile in the recrystallisation Q
also waffled for the Q on why the trans is blue and the cis orange
I didnt have a clue about that question, thanks, What about the N.M.r and I.R one?
Also how do you think you did on the polymers, protein and steel one?
You know the question about the molecule thats breaks up and you have complete compound A and draw the structure for compound B what did you do?
I loved that exam, mainly because a lot of the stuff I had been revising and practising came up. Our chemistry teacher gave us just about every past paper dating back to 1993, and it's interesting to see that they just recycle some of the questions from a few years ago. Oh well, won't know the result until judgement day I suppose.
Also what were the answers to the solubility question cause I just guessed my way through that one.
Err can't remember my exact answer but basically the concentrations were both halved because the volumes doubled as they were being added together. I got the concentration as being more than Ksp, so a precipitate DID form.
That's just me - hope other people found the same!
thought polymers, proteins etc. paper was ok - but i thought this one was harder, especially because i knew a lot of the chemistry, but just don't feel i put the write wording down for the marks. and i think with salters, u have to get the exact wording, b/c when u look at the markschemes they are quite specific - and i think some of my answers may have been too vague on hindsight
