    SOMEONE ANSWER
    What was the question on C3 - the last question- asking about the mass? What was the exact question?
    i put the fact that the sodium hydroxide was no an independent variable , and the fact that the values of the graph will change but have similar proportion to the graph of results meaning the difference in both temperatures(start and end) will be the same as the graph

    the question asked about changing the amount of sodium hydroxide not affecting the graph of results and having the same difference. something along the lines to that.

    Yeah I got 50cm + 25 too.
    It was asking for mass at peak temperatire therefore, 20+25=55
    55*4.2*(38-18)

    Yes, they will probably just ignore that because you still got the actual name right

    She already had 25cm^2 in the beaker.
    She added 50cm^2 total into the beaker also. (This is not the peak, as she added excess. Basically on the end of the xaxis).
    OVERALL temp change was 10.

    So (25+50) x 4.2 x 10 =
    3150 J

    Oh thats were I went wrong then, I forgot she added excess. But I would still get marks for doing the equations with the right numbers that I got.

    What do you mean "the tier" do you mean choose between higher and foundation

    Yeah - in our school were not even allowed to pick between foundation and higher. Ive been entered for foundation english language which is stupid as i obviously have the learning capacity for higher tier. i will now have to redo english language in year 11 which means i am wasting a year of my learning time...

    Do you mean stupid? Stupendous is a synonym for "amazing".

    For the question about metal oxide, do you guys think just saying 'insoluble' would just get the mark? The question context was about soluble and insoluble compunds.

    What did everyone write for the equilibrium question as the forward reaction was endothermic!? Does the amount of product produced increase or is it the reactants.

    I dont think so however insoluable base might be allowed
