Year 12s: what will be the first way you research your future options? >>

Official Chemistry A F325 - June 2016

Here we go! We can discuss exam questions or general content if you need help.

I won't be revising for a while but if I can help, I'll try, means less revision for me in the summer if I help people earlier on (or if people explain to me!)

And half of module 1 of unit 5, which I will resume by the 20th hopefully!

module 1 is fun lots of maths so fine. Module 2 is interesting. How do you study chem? Do you do it all in one day as in only revise chem or space it out :smile:

Hm I space it out, So I revise a topic, do topic specific questions and then once I've finished all topics I'll do full past papers
What about you?

I see. Do you do past paper questions whilst you are doing the questions.

I make notes on sections from all my revision guides.

Then do the papers.

Have you seen Jan 2013 F325 lol.

equivalent to june 2015 f324.

I really think that they will change the born haber questions this year. They have been way too easy in previous papers :P

Standard titration question as the last one though :P

From what I understand, [ ] means concentration in mol dm^-3, so to convert g dm^-3 (another measure of conc) to [ ], you can do (conc in g dm^-3)/Mr, which the mark scheme describes. I find it helpful to visualise the units: (g dm^-3)/(g mol ^-1) = mol dm^-3. Then you can rearrange for [H⁺] and find the pH. I hope this made sense :smile:

The first part was fine. The redox bit killed me. :confused:

I found it horrible because of the redox/titrations questions which was the last half of the paper. However the first half was good and pretty simple.
