    Wasn't it 2Cl- and 2H+ and 2e-? At least what I wrote and what my textbook says.
    I wrote 75kg too, not sure if it's exactly right.
    And my textbook would agree on B as it shows that the Sun is at the very left, next to when the orbit turns.
    Yh thats what i got i didnt use the e i used H+ + E- H2
    OH- + CL- CL2

    2cl- - 2e ~~> Cl2
    This is what revision plus book says.

    Damn, I just realised too, I wrote down everything with confidence and just had to forget reduction and oxidation.

    I thought it was B because that was when the speed of the comet was at its quickest. The speed of a comet increases as it gets closer to the sun.
    That's what I put, that's right

    What did everyone get for 1 a)? It was a question about why it is important that the sperm whale population does not fall to a critical level. I put that it may cause the food chain to become unbalanced.
    I just put that they will risk becoming extinct

    What will be the predicted grade boundaries?
    high i'm guessing... the 1s were very easy which threw us off as 2s tend to be easier. depends on what we all get. if we all do bad then the grade boundaries will be low if we do good then the grade boundaries will be high. if its varied then it will be the same.

    What do you expect the grade boundaries for an A to be?
