    How many marks was Question 3 worth? It's been cut off in the photos of the paper! :/
    Also how many marks was the Kc Question worth?

    And for the weakest to strongest acids, you write it from the largest pKa Value to the smallest yes?

    Just when you think you have the marks - you look at an OCR mark scheme. No scope for interpretation. Just look at January 11 F321 exam there was a halogen question which had a national average of 0.0 students getting the question right. Why because if you wrote halogens are toxic, 0 marks, must specify bromine is toxic. The people that write these papers are out of touch with the real world.
    Well... true. I remember in one paper they asked something like "What are the advantages of bio-ethanol?".
    It is a liquid. There is no other advantage. If you dared to propose one of the many other advantages, you are wrong.

    But I have generally been happy with the Chemistry course and papers. It is tough, but (contrary to what everyone else seems to think) I always thought it was fair.

    OKay now looking at the paper. I think i should get 40 marks at least. Is there an unofficial/official markscheme yet?

    Edit: Now that ive counted, i think i got 55/100. Anyone know the grade boundaries?

    why was no2 cooled and put under pressure? i said cooled beacecause endothermic more products and pressure increase to increase rate of reaction!

    can douche bags stop talking **** about how the questions were this and that, when they give you a graph with a semi-constant half life, they give you complex ions polymers, and a buffer solution with only a pH with no indication of how to choose a damn acid... shut up, and suck a fat bay's D.i.c.k. lol

    I used le chatelier's principle. Cooled to favour exothermic (forward), low pressure to favour low moles if I recall correctly (forward).

    Pressure also increases products as there were less moles of gas on the right.

    ok if you did so well go have a **** to celebrate...
    There is a direct correlation between the quality of posts made and how well people found the exam. With responses like that it is no shock to me that you can't handle an A level exam.

    Peace out bro.

    In one of the past papers (maybe Jan 2011?) there was that question on the hair straightening chemical. That was way harder than Magic Tang.

    The polymer question was perfectly reasonable, they had basically drawn out the structure of 4,4-bipy for you (they gave you 2,2-bipy) and then you just need to add an ion with 4 water ligands attached. As an A (but not A*) student myself, I can say it was not overly challenging.

    The Magic Tang question was tough. I missed the point of it and would be lucky to pick up more than a few marks. At the same time, though, if it was not in their how could they differentiate between me and the A* students? I am okay at chemistry, I will get an A, but I am definitely not talented enough for an A*. That question had to be in there otherwise plenty of people like me would have done, frankly, too well.
    All but 1 of the marks in that question was for using the same old formulae in a slightly intelligent manner (which I failed to do). Not beyond the scope of the course, just difficult.

    And the long questions were a gift. You say "wordy", but they weren't wordy at all. They were long, but if you have written an essay for it then you completely missed the point.
    The last question, most of the marks were for calculation and ionic equations.
    The 7 marker was the only question with a significant 'wordy' content, which was 4 definitions and a few diagrams. Being given 4 marks for some definitions is an absolute gift, and they are not very long either.

    It was a hard paper, sure. But it is A2 Chemistry (one of the hardest A-levels). What do you expect? It was hard for you, it was hard for me, it was hard for 99% of people. That is why you only need ~65% for an A.
    I agree with you, but you've said it in a way that makes you sound like an absolute toff.

    There is a direct correlation between how up your own arse you clearly are and how well you think you did in the paper. Let people who found it hard discuss how hard they found it, and come to their own conclusions, and maybe if you stopped looking down your nose you might see something. peace out "bro"

    In what way?
    I am definitely not a toff generally, although perhaps academically 'snobby'? I have little time for people who run around complaining the exam was 'impossible' when plenty of us found it fine. Difficult, but not by any means impossible.
