    For organic the definition of oxidation and reduction slightly varies, oxidation being either adding oxygen or removing hydrogen and reduction is adding hydrogen or removing oxygen. Plus an oxidising agent in one reaction isn't always an oxidising agent in another.
    More often than not, Cr2O7 is an oxidising agent. Plus in this case Cr changed from 6+ to 3+. Therefore, it is the oxidising agent so it leaves C2O4 (2-) as the reducing agent

    How many marks would you lose for not subtracting the volume of P to get the volume of Q?

    So if I had the rest of the working until I got 1337, and I just didn't do 1337-1330, I'd get 2/3 marks? :/

    I got an A in the specimen and an A in Chem in 2015. I repeated it and did the new spec. and wtf..I did not get a single question right. What was that ****? This is ********. The relative atomic mass questions are supposed to be free marks. There is supposed to be enthalpy change. What was that?

    ye aluminium cuz 8 electrons were removed and boron only has 5. I put boron then crossed it out straight away when i clocked.

    Roughly the same proportion of students have to get an A every year. Considering that last years paper was vey straight forward this years grade boundaries will be lower. On top of that it's a new spec and grade boundaries have to be lower as we are the first year so have very few resources (past papers) to rely on.

    That's very true but all the papers in the last decade have not been of the same difficulty.
    Some have been harder than others yet the grade boundaries have remained the same, at 80%?

    I guess that might be the case but this year we have a new spec and also you have to take into account the 6 mark levelled response question which is also new and will result in many marks being lost if not answered correctly.
