    Every single edexcel paper have been leaked i believe
    I very much doubt it has. There was no evidence that the maths paper was actually leaked apart from people hearing it from someone else who heard it from someone else etc.

    Are you even sure that school's get delivered R papers along side non-R papers? I thought schools only got delivered papers that their candidates sit (I.e. they get sent the papers that the candidates sign up for) to avoid leaks and possible cheating. It would be logistically impossible to send all the colleges R papers in time for tomorrow's exam.

    MCQ Q3? Its D because a magnetic field is what accelerates the positive ions. Electron gun ionises them

    They investigated and there was no evidence that it was actually leaked. Stop worrying about whether the paper was leaked anyway it makes no difference to you what paper we sit.

    you said ammonia to nitrogen was 2 to 1 ratio so what i did was take 500 and divide it by 2 which gace me 250 and you said 50 nitrogen was produced
    It says 20% of ammonia is decomposed
    So 100cm3 decomposed

    Can anyone help me with this question:

    Like ammonia, hydrazine is a base that reacts with water to form negative and positive ions. (we know hydrazine is H2N-NH2)
    i) Write the formula of the negative ion that is formed when hydrazine reacts with water
    ii) Suggest the formula of a positive ion which might form when hydrazine reacts with water

    The answers are:-
    i) OH-
    ii) N2H5+ or N2H6+

    Although I've got no idea how you would get these as your answers??
    For the second part, as the hydrazine acts as a base, this means it is a proton acceptor (definition), so the N2H4 accepts a H+ ion to form N2H5+.

    Not sure how to explain the first part, but the other ion in water is OH-, so I suppose that is what is left when the N2H4 accepts the H+? (sorry for terrible explanation)

    Sorry, yes it is C. That question was very sneaky. I've learnt it as it being accelerated by an electric field. A magnetic field is used for deflection. Charged plates would act in the same way as an electric field
