Need to learn these equations asap... My teacher gave me a list of all the equations we need to know for C5, do you want me to post it?
Is there a specific description for giant ionic lattice structures? The definition in the book is quite vague...

feeeling okayISH :s-smilie: C4 - pretty much nailed, C-5 needs a bit of work, C-6 is really hard so not as confident with it :s-smilie: how about you?


6 markers...I predict
C4 - purification of water or something about a type of bonding or reactivity of a group.
C5 - titration or equilibrium
C6 - Hardness of water...ozone!?

guessing really :P

What grades are you guys aiming for? :smile:

I think we should start a question/answer practice thing.


How do cfc's affect the ozone layer

There's an equilibrium in like every paper -.- that's maybe likely and also maybe finding the concentration/ mols (the one that requires 3/4 steps)
