    That was a tough two marks tbf. Remind me again of the reactants and products and i'll do it again. Can't be sure it's right but mine was balanced.
    it was I2 in alkaline making I- and I(V) and water,
    I tried to do it like 3I2 + OH- + H+ --> 5I- + I(5+) + H2O
    but im not sure cus it didnt say that H+ was involve in the reaction and the condition is alkaline

    Clearly not much if EVERYONE I have spoken to, including people who have done pretty much no revision, has said that it was probably the easiest paper they've ever done.
    Well nobody is going to say that they found it difficult if this is the attitude you have; belittling people who found it harder than you did.

    It was neutral until the people who found it hard started attacking everyone else. Not cool to take your anger out on others.
    There is no attacking. There is just CONSIDERATION for people who found it harder. How would you like it if you were say... running a marathon and an athlete came up to you and said
    "your time is rubbish that was so easy because it was like perfect conditions to run a marathon"
    and there you are panting and sweating like a damn pig.
    YOU WOULD BE ANNOYED.
    So please I am begging you to just have a little bit of empathy and maybe don't rub it in other people's faces that it was a "easy" paper for you.

    Think I got

    6OH- +3I2 -----> 5I- +IO3- +3H2O

    it just said I(5) so i wrote I (+5), now that kinda balance out

    It said Iodate(V) iodate has I and O, im sure thats right

    yeah that's right, i didnt read the question carefully enough, lol literally spent 5 minute balancing out the equation without reading the question

    Was the first reaction with hydrogen peroxide or water?

    omg! this was like 3 marks I was so confused do you remember what the reaction ended up being?
    (Original post by HFancy1997)
    Did anyone balance thr Au equation and I2 equations? They took soo long to do omg-.-

    I think this is what I put?? If I remembered correctly lol:
    4Au + 8CN- + O2 + 2H20 = 4[Au(CN)2]- + 4OH-

    For the multi step reaction mechanism, did anyone else get 2 of the steps the same?

    H^+ + OH^- ---> H2O

    Spent about 5 minutes checking and everything cancelled to give the overall equation
    I did this too and it did balance so isnt technically wrong but i guess we could have combined the 2 same steps at the end... No idea whether theyll accept it or not

    No one is rubbing it in anyones face (well maybe the previous guy was). But at the same time, have realistic expectations for the grade boundaries.

    ok thank you! But why would that be 3 marks? strange

    Ahh the reason you couldn't balance it is because you was supposed to write it as IO3-

    3I2 +6OH- ---> 5I- + IO3- + 3H2O

    that's the equation I got.

    Not sure why you have both H+ and OH- xD it said alkali conditions so only OH- i think?

    So you consider the opinions of a few (let's say 7) that only you have spoken with to be representative of the whole cohort? I.e The 1000s of students whom you didn't speak to.

    You couldn't of gotten an A in this paper without revising. That's the stupidest lie ever. If you didn't revise, you wouldn't have known about ligands, fuel cells and the concepts surrounding buffers. All which featured heavily in this paper as application of knowledge style questions.

    It was 2 equations for 3 marks if I remember correctly.

    No point feeding the troll. Although, the majority of qs were recycled from past papers (which is something I love about OCR compared to AQA).

    Damn, I think after finding the moles of Cu2+ I worked out the molar mass of the wholecompund by dividing the mass they gave by moles of Cu2+. Then, I took away molar mass of Cu(HCOO)2 to from that to get the molar mass of water. Then divide by 18 to get 17 for X.
    So basically, I used the method on page 220 in the textbook.
    I never thought I would find someone who made the same mistake as I did. Hope you managed to get the grades you need. Was hoping for an A*, but I f**ked it real bad.

    yeah i was do desperate that i ended up adding one H+ to balance out the charge lol, now that make sense
