    erm basically revise moles calculations, percentage error, balancing redox equations and u'll be fine.. the rest are some worded questions tht r worth 5 marks

    I'm doing the volumes of gases evaluative paper on Friday.
    I've revised molar calcualtions & percentage errors & balancing redox reactions, but I was wondering if there's anything else screaming out that I've missed?
    My teacher suggested looking over any practicals in unit one that produce a gas,
    I came up with acid + carbonate and acid + metal..... are those it?

    Thank you! Please Help!
    the last question is a tick box and the answer is same voume and greater volume, the question before that is a balancing reaction thing between mgc03 and nitric acid so learn that. the question before that is a question asking how much gas is supposed to be produced and you add 120 and 50 together, the first question is what was the error, the answer is there is no water, then the next question after that is some moles question and you have to work out why mgco3 the acid is in excess.

    If i'm right i think we did this one before christmas, its a simple redox titration, nothing to worry about, normal ensuring no mass of solid is lost and clean equipment, the end point is really clear. Just read the script and make sure you give your answers to the right number of sig figs (they make it blindingly obvious) don't worry about it's very similar to AS titrations.
