    I really hope that they're very kind on giving marks in that 6 mark question. What was the most common answer for the percentage mass of MgCl2? Do you think they'll give me 2/4 marks for calculating the moles of BaSO4 and stating it was BaSO4?? My final answer was 29.5% but i don't think anyone got that so :/

    This paper was ****** stupid
    Wanted to walk out 20 minutes through
    Didnt have a clue on titrations or the redox part. These aqa ***** have a fetish for titrations.
    Completely blagged the 6 markers
    No Kc, Enthalpy, Hess Law,Calorimetry, Empirical Formula, Definitions, Le Cheteilers Principle, or any of the simple ion tests. WTF dude
    The dumass tap question.
    Guessed all of the multiple choice
    They decide to throw physics into the mix
    Hitler should really be pissed of today...
    Anyone made a video?
    I totally agree with you, I wasted all my time revising stuff that didn't even appear as a one marker in the exam.

    me to , I got that aswell

    did yous deduce that it was barium suphat eand use mr of this and mass to get moels and use a 1 to 1 ratio and time is by mr of mg cl2, and the number you got divide it by the mass of the original powder ??

    Have you seen the last 5-7 years grade boundaries, it never falls below 80%
    and have you seen the papers in last 5-7 years, piss easy, piss easy. If actual difficulty of exam is what decides the papers, then if previous papers were 80%, this one should be around 60%, when in comparsion to previous spec,
    But aqa are going to be c**** and probably only redcue it to about 75%

    the number of moles i calculated for HCL used in that titration was probably more similar to the number of marks I gained in that paper than the actual answer ... 9.38 * 10 ^ -4

    Percentage yield was 49.3%
    Thank god. That's exactly what I got.

    Did anyone do the CHEM 1 resit?
    Ya! How did you find it?

    I was wtf for the mass spec question. I put for the similarity the number of peaks and for the difference I put height of the peaks. I know that's completely wrong. For the percentage yield I put 49.3% I think. And then the last question which method would give the highest atom economy, I guessed and put the first method. But I just guessed. For the cracking of an alkane to produce one molecule of octane and ethene and a compound X what did you get as the molecular formula of the alkane I just put c12h26 no clue tho.

    YES
    I considered chemistry as my best subject but honestly, after that exam I don't know what to think :/
    I hope the grade boundaries are low, and paper 2 is easier so I can bring my grade up

    It was honestly so horrible! I think I ruined all chances of getting an A, going to revise like crazy for paper 2.

    Same here ): but I need an A in chem since I'm thinking of going into chemical engineering ahh
    I'm feeling 60-70%ish, looking at the unofficial mark schemes
    Hopefully I can bring up my mark

    Guys it was a hard exam, and I'm saying this because a lot of you are worried. Don't be, all we can do is revise for the next one now. I know it's hard to get your mind off it but i know everyone and including me have worked our socks off, we can't turn the clock back, we wish we could but we can't. What I'm saying is that it's half term now, so guys just take 2/3hrs rest, every single one of us deserves a bit of rest These exams are turning us into robotic like things :s It's always better to keeping walking forward than walking back all the way and realising, nothing is left...

    Predictions A: 55-58/80, B: 48/80, C: 39/80
