hoping there's something about the earth's early atmosphere, or the changes to get the atmosphere to how it is today (the only thing ive really revised, whoops)
Ayyy! I've got literally every single past paper, just looking through the Chemistry is making me want to give up. i predict it'll be tough! I have no idea on the type of 6 markers on the Chemistry paper, only concentrated on Biology till now.
Could be pollutants or early earth for C1, fractional distillation, nanotechnology or property changes from polymers for C2 and for C3 it could be electrolysis, processes that form rock, continent movements or salt?
Ugh I hate chemistry and physics kill me now :/ So nervous for them.
I think it'll be C1 - different types of air pollutants or maybe a 'look at the data' Q. C2 - Fractional distillation or polymer modificiations C3 - Mining of salts or electrolysis probably?

Have you got the 2014 paper? I'm the best at chemistry out of all the sciences sooo pretty confident...
I suspect C1: Carbon pollution, nitrogen pollution, sulfur pollution or early atmosphere C2: How to modify polymers or crude oil/fractional distillation C3: Salt/solution mining, dangers of salt, uses of alkali's maybe?

Or Electrolysis and the uses of the products produced by it for C3

Yes, we did the 2014 paper I believe for the mocks. But I left it at school :/ Ill hope to get it back tomorrow, and your predictions don't seem far off!
