    I got something like 55.1J for the q=mcAT question but I don't know if its right (that number might not be exactly what I got but it's what I remember)
    That's what I got as well, I thought it looked wrong when I did it but I double checked and got the same answer.

    Its Rb because in group 1 (alkali metals), the Boiling point and Melting Point decrease as you go down. Rb was the last Alkali Metal so its the lowest Boiling Melting/Point.

    On the specific heat capacity question I think I got an answer of around 55.104? Didn't you have to do 0.8 x 4.2 x (38.4-22.0) since that was the temperature change?
    thats what i got!!!!!!!

    0.8g was the mass of the ethanol burnt but that was not needed in the question you needed to use the 50g of water. You'll probably still get 1 or 2 marks.
