Why would you say charging? I thought it would be discharging as the question states it's 'recharged' already.

Are you doing AQA??
There is a lot of content no doubt divide your topics and cover one part of the spec each day like eg from transition metals do catalysis one day then ox States the other
When you finish the content and go over it I'm sure you'll find it okay!

I found unit 5 (aqa) really hard at first too, but if you go over the content enough times, it's all just memory work
I'm doing edexcel but still pretty similar and yeah I'll just memorise all the content and then hopefully the papers will be a lot easier

No idea. Look at the spec.

Also MgOH is not a thing.

I was looking for a Chemistry Revision Thread but there were not any so I decided to make one :wink:

Feel free to ask questions regardless of your exam board (because chemistry is chesmitry), and we'll all be happy to help!


lol wut.
