    I LOVED that paper. Seriously thinking I could have gotten a decent A on it and I was only aiming for a C/B! :O

    Also, thanks to everyone that suggested MaChemGuy for revision! His mechanism video and past paper videos were super useful, definitely going to use them to revise for F324 and F325!

    did anyone get something like 347.2kJ, 281, 1482 for energy?
    I messed up the percentage yield somehow, got 11.1g
    and for the EU questions i just couldn't work it out I think i got 740l or something ridiculous
    also C3H7Br for analysis? And then CH3CH2CH2OH, NaBr, and CH3CH2CH2ONa?
    otherwise it was a decent paper but i don't think it's much easier than any of the past papers

    Was super happy during the whole exam, thinking that I only dropped a few marks in the whole paper, but what if that's not enough for an A? XD

    This is what I remember from my calculations.

    Magnesium Mass : 0.38 g or something along that

    CO +1602
    Volume: 259.09 Litres
    Enthalphy of Nonane: -230 something
    Enthalphy of Reaction using Temp change: -34.7 or similar
    Repeat Units: 50000/70

    Let me know what you guys got

    what you had to do was divide the mr of the monomer which i think was 1-methylpentane by by the large number they gave you

    I got 259 litres, 0.38g for the Mg one, 1602 for the CO one and that for the repeat units one. Can't remember the others though

    Can either of you remember the question for the number of litres of petrol one? My bro sat the exam today and wasn't sure about his method so I want to go through it with him but he can't remember the exact statements...
