    omg you are kidding me, for the overall equations we had to write NaCo3???? and HCL??? SHOOOT.
    I really doubt it, the entire country would have done ionic equations

    experiment to test if MgO was ionic;

    i forgot to put that the pH will be weak alkaline
    I said to heat until molten etc....

    Any unofficial mark scheme at all?

    Any thoughts on grade boundaries? I think about 72 for an A maybe! Definitely a harder paper than usual!
    I definitely think the was on the same level if not slightly harder than the June 12..so I think between 75 and 80 for an A*. I'd say 70 for an A, and 77 for an A*

    OMG that's what I got! If it's right I'll kiss everybody I see today :P I really thought it was completely wrong.
    Thank the lord I'm not the only one! I kinda knew it was right because it was really similar to the June 12 very last question, so praying that I've got all the marks there! Was it 4?

    I think it was as follows:

    [Cu2+] on LHS is less than on RHS. Therefore, the equilibrium:

    Cu2+ + 2e- <---> Cu shifts LEFT to oppose the reduction in Cu2+ conc.

    This releases more electrons, so LHS is relatively negative to RHS

    Therefore current flows right to left. Did anyone else get 1:3 for the last question?
    You rekon its fine to mention the differents in molar conc and equilbrium shift, I didn't write an ionic equation like that, also was one mark and a single line to answer?

    For the question where it asked us to work out the e.m.f of the negative electrode i got like 2.75 or something...i think it was a positive number.....I did cell+left electrode??....because i thought the negative electrode was where the reduction reaction happens, hence it would be on the right?! ... FML !!! byebye uni ..
    :erm:

    To be honest guys I think you might as well go off and revise/have fun. Speculating now isn't going to help.

    Its -3.05v -- at least thats what I got, its only a one marker anyway--

    No the negative electrode is on the left (oxidation)

    Guys on the plancks law question were you had to determine whether deltaE would be higher,lower... i put lower because frequency of red light is lower, so deltaE would be lower and so on..... I'm just unsure whether i read the question wrong, did it say would deltaE of red... be higher/lower than deltaE of blue light or the other way round. Also, Grade boundaries any1?

    it does. High conc. of ammonia displaces water and OH- ions...page 240 Nelson Thornes book.
    Thats with metal 2+ ions. Look at the table with Alluminium excess NH3 in the table at page 243. I might be wrong but in the table it says that.

    Oh also, before the exam i heard a boy talking about "I hope cobalt as a catalyst comes up", and I have never heard about it! (neither had my classmates... seems like a fault on the teachers part im not sure).
    So i was praying it didnt come up and well, it did :lol:

    dont you just say melt it, pass electricity, if it conduct tn its ionic bondin? same question came up before but with al2o3?

    I got that ratio too.

    I'm unsure about the complex.

    I think so.
    Ah okay :/ I also found a lot of the "explain" questions tough. Damn AQA, they really pushed it this year!

    I thought so - I put no visible change aswell
    Oh I should've written that! Btw, I owe you so much! I have a bit of leeway with this paper thanks to my ISA!

    Heeeell no! I believe CO32- is okay, as is Cl-

    (Original post by cat-lover)
    I wrote down both as colourless so I'm hoping that's right.
    Aha hope and praying!

    I put energy would be higher because blue light is absorbed which has a higher frequency so higher energy. Red is transmitted
