    Nope it was 100% definitely exothermic! It said in the qu! Stop making people worry unnecessarily, if you don't know for definite, don't say.

    You don't rearrange the equation though, I think it'd one for correct things used in equation, one for using equation, one for result.
    I'm sorry I meant
    1 mark for Finding the temperature change
    1 mark for substituting the values
    1 mark for finding the correct answer

    Hopefully I get the first mark
