Hey- well i did higher chemisrty and got an A so I may be able to help you a bit! However- I gave up scinces 2 years ago so Iv forgotten ALOT about the subject! Am I right in thinking that chemial formulae is the make up of the chemical?

eg Carbon Dioxide- CO2

This is because there are 2 oxegen molecules for every one Carbon moelcule....

If im talking about the right thing, pm me if you want and I'll try and remember what I can!

PS- I also had loads of difficulty with this- but I always used to complicate things much more than I needed to. I think one day it just clicked and the mental barrier disapered! Does anyone else have this problem?

You could try drawing pictures of the chemical and labelling the molecules so that you could see it visually. It works better for some

Try writing them out in different coulours (colour helps memory, for some reason) on post-it notes and sticking them all over your home. That will help you remember.
If you're really struggling, myybe you could ask your teacher to lay on some extra lessons at lunchtime. If this still doesn't help, maybe you could ask a friend who is good at Chemistry to help.
Buy CGP revision books. They are really helpful for Science and Maths.
