AQA GCSE Chemistry - C2 and C3 15th May

So its a lot quicker than using CGP?

Anyone got the C2 or C3 January 2014 exam papers?

Also, any predictions for this exam?

There wasn't a January paper, was there? I thought they got rid of all the January exams

Apparently not because, biology had an unseen B2 paper which was posted a day/two days before the exam.

I think the 6 marker (or one of the six markers as them seem to be putting two on every science exam now!) for C3 will be on hydrogen fuel cells. It hasn't come up yet and it's one of those topics they're likely to give you data on and evaluate.

Good luck everyone. I know cryolite lowers the melting point of the aluminium (I think).. but how does it do it? Do we need to know that?

I did this in class the other week, the six marker was on paper chromatography.

My predictions:

C2: Percentage yield,empirical formula, percentage mass, reacting mass calculations, making soluble/insoluble salts, electrolysis/electrolysis of brine/electrolysis of aluminium oxide and why cryolite is used. Certain questions based on particle collision theory, acids and bases, giant covalent substances eg diamond graphite , gas and paper chromatography etc

C3: Tests for positive/negative ions, titration calculations/method/how science works element, almost definitely think that something regarding calorimetry calculations will come up (energy transferred= specific heat capacity of water X mass of water X temperature change), mendeleev, hardness of water

I could be wrong, but based on past papers and what they seem to like talking about.... however they could do something random like the magnesium ion question in Biology b2 so what do i know....

thats almost every topic
