    Does anyone know what the grade boundaies would be for an A? Our teacher said its unlikely to be 80% as it usually is because its a new spec but im not too convinced? Im worried I might just slip below the grade boundary if its truly 80%

    for the enthalpy profile diagram. did u put N2 (g) and O2(g) as the reactants and N2O2 (g) as product.
    and +82kjmol-1 was the enthalpy change right
    I'm sure it was N2(g) + 1/2O2(g) and on products N2O(g)

    I think 80% is a fair bet because both papers weren't that hard. It might be 77% but don't think it's going to be much lower than that

    I think I've got around 113/140. It is tight. Hopefully grade boundaries will be low enough

    on the depth im floating around 55 ish hopefully i did better in the breadth

    well scared for results day. I need AAAA in order to get into medicine really. hope the grade boundaries are low as well, cos these unis like UCL look at the ums as well. that is how deep medicine is. omg

    S1 next week. how r u guys feeling about that if you do maths??? Maths is the easiest subject I take I reckon. C1 and C2 banged, although there are comments about the C1 being nasty, and I checked the unofficial mark scheme and it was great. hope the same for S1 .
    to get an A* at A level, you need to get 80% average across all 6 modules c1, c2, s1, c3, c4, m1. and 90% average between c3 and c4. so c3 and c4 are the most important.

    Yeah I agree, c1 and c2 were good. M1 was also good so hopefully s1 will be the same next week. And then d1 will hopefully be good but never know with that one. Good luck. Do you think you did well today?

    yeah it went really well. in fact better than the breadth. what about u?

    Good to hear, yeah it went well today. I think I I lost 5-7 marks on silly things. Also depends how strict they are

    less hydrogen is produced because there are fewer moles of the metal used.
    do u think I got the mark or do I have to say cos the atom has a larger relative atomic mass as well for only a mark, cos u know ocr can be soooooooooooooooooooo specific in the newwwww spec

    we don't know as the mocks weren't properly standardised etc

    I just road loads extra to ensure I get a mark (without wrong info ofc!)

    for the difference between sigma and pi bond. I put sigma bond has a higher electron density than the pi bond. do u guys think i got a mark here
    No, a pi bond does not have a higher electron density.

    A double bond (i.e a sigma + pi) has a higher electron density than a single bond.

    I spoke about the distribution of the electron density.

    I think the simple definitions would be enough, so I wrote
    sigma bond is direct overlap of orbitals and pi bond is sideways overlap of p orbitals

    Do you think that me writing that the bond enthalpy for sigma is stronger than pi bond for the difference is correct or not
