    You see I got that, but I thought it was wrong! So I then changed it to 45c, but that still seems like a lot.:confused:

    How do you balance an equation?
    e.g. CaCO3 + HCl ---> CO2 + H2O + CaCl2

    I noticed it was in past papers but we never did it in class :confused:

    Balance the elements on either side:
    to balance this one just put a 2 before the HCl.

    CaCO3 + 2HCl ---> CO2 + H2O + CaCl2

    Then you have:
    1 Ca on either side
    1 C on either side
    3 Os on either side
    2 Hs on either side
    2 Cls on either side.

    Please stop :eek: Science is over and if I ever see a balancing equation ever again I will scream :cool:

    Not at all! Sure 450c is the same as €4.50! Examiners aren't that mean:p

    Book 1:There was a book where you had to write up all the mandatory experiments you were meant to have done over the 3 years. (Some schools just use a hardback to do this)

    Book 2:This was the green book we got a few months ago when we had to write up our one day practical experiments (on 2 of: "factors affecting the distance a toy car travels after rolling down a slope", "the best indigestion remedy" and there was one more on Biology, something about plants). It was in this book that you had to tick the boxes saying you had completed book 1.


    COURSEWORK PROCEDURE.

    over your 3 years of jc study you should have done 30 compulsory practicals, worth 10%. this is coursework A. you should have ticked off boxes in the little green sec booklet to show which of these experiments you have and have not done. then between january and april of this year you should have done 2 further major practicals, worth another 25%. the full reports for these should have been written into the same green sec booklets. these green booklets would have been completed some time in april, probably, and then collected by your teacher. they were kept in your school and are sent off with your actual science exam to be marked.

    now, regarding the coursework A, the 30 experiments. the dept. may require proof that these were actually done! this is where your hardbook notebook or report book comes in. over the 3 years you would have been completing reports on the experiments or filling in the report book. your teacher SHOULD have collected these from you in april also, and kept them. they SHOULD be kept in the school until next christmas, just in case there is any query by the dept as to whether the experiments were actually completed or not. ie do the ticks in the green sec booklet actually match the work done!

    interestingly, the department just require 'proof that the experiments were completed'. so, if instead of doing reports of the 30 experiments in coursework A, you could, in theory, submit video or photographic evidence for each expertiment!

    ok? :)
