    Ok never mind batteries I'm still confused on Born Haber Cycles anyone got a quick way to do it without drawing it?
    I think drawing it is the safest bet... if you know all your enthalpy definitions it should be straight forward... you're just converting the compound into its ions one step at a time.

    I'm so completely ****ting it right now. 3 hours. 3 more hours. then I longer have any control over my fate

    ... I think I am screwed. I do not feel prepared at all and I need a B for university. Good luck though everyone! Hope the paper isn't too bad.

    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

    Uh oh 2 more different bits of advice I assume both of those 2 would work.. I hope. Anyway seen as it came up in.. january 2011? Hopefully won't come up anyway Not that I feel much more confident on the rest of the unit

    Jan11 3d) Separate samples of phosphorus(V) oxide and sodium oxide were reacted with water.
    In each case, predict the pH of the solution formed and write an equation for the
    reaction.

    Just read this and thought they meant the two react with each other oh ****kk... It's like my defence mechanisms are just expecting trick Qs =/

    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

    they lose from 4s first
    that's why for example Cu+ would have a full 3d10 orbital...

    All that time I spent learning that table of 6billion different colour changes, and there was only one measly 3 mark question on it!
    Thought it was quite a nice paper though, which makes a change for AQA :p:
