AQA - Unit 5 - Energetics, Redox and Inorganic Chemistry

Ok never mind batteries I'm still confused on Born Haber Cycles anyone got a quick way to do it without drawing it?

Do it in your head? :P

Hope the Aluminium questions don't come up, seen few posts on this topic about it. And my book says [Al(H20)2(OH)4]-, another one says [Al(OH)4]- and then the markscheme when it came up in a paper said [Al(OH)6]3-. God knows which is right.

Glad biology went well as this could be a shocker

The text book gives it as [Al(OH)4]- in the table on page 243. I'm guessing that's the safest bet

The markscheme for the [Al(OH)6]3-, had comments in the side bit saying allow the version that's in the books [Al(H20)2(OH)4]- I think

Really small q, for electronic configuration, the t metals lose 2s before they lose from 3d. But do Cr and Cu lose 14s first then the 3d or do they lose the 3d ones first, and then if theres any left, the 4s ones? I'm really confused :/ Anyone? Thanks

Good luck everyone and thanks for all the help! I wish I had gotten up a bit earlier so I could check if i knew it all.

Good luck everyone! And stay calm because they can't test us on anything we don't know Fingers crossed for a nice paper!

when has that ever stopped aqa? :P

True Stop with the negativity, it's gonna be a great paper
