    We're the first year to do the new spec for all units.. so basically last year was our first year doing unit 1

    For unit 2 Electrolysis is pretty much the only six mark question they can really ask. Polymers maybe as well.

    I have a feeling it's going to be a question where we have to apply knowledge.. so probably nanoparticles!

    yeah, nanoparticles is a new topic and they love putting in new stuff into exams so possibly...

    Do we need to know the conditions in which polymers are made from (e.g low pressure high temperature)

    Yes the specification gives a brief summary on what we should know.

    6 marker on maybe describing different bonding? Maybe touching on haber procces/ making new chemicals

    I Know, but they do touch on it when discussing reversible reactions, so they could use it as an application and give you some information to do a six marker

    I've been doing C2 past papers, normally only drop 1 or 2 marks as the questions are very repetitive and its easy to learn the mark scheme.

    Yes the specification gives a brief summary on what we should know.
    However we just need to know that they are made with different catalysts and different temperatures/pressures, we don't have to know the actual temp/pressure/catalyst used.

    From my new spec AQA Text book:
    "Ammonia is manufactured by reacting nitrogen with hydrogen at about 400°C. Unfortunately, hot ammonia decomposes again."
    We don't have to know about it in detail but it's definitely mentioned a few times and if they were going to use 'reactions that go both ways' as a topic for a six mark question i imagine they would bring in questions about ammonia.

    What would be the points for a 6-mark insoluble salt making question?

    1) Mix ionic substances in solution
    2) Filter/wash/dry precipitate to obtain salt.

    Is there anything else??

    Also what kind of things would they look for in a 6-mark electrolysis question?
