There are two questions on the same test paper.
- Calculate the amount of heat energy, $q$, produced in the reaction
- Find the change of heat ($-q$).
I'm not sure whether or not they mean the same thing, but I highly doubt it seeing as though they would have the same answer, but as I said, I'm not sure. In question 1 I know that the reaction is exothermic and therefore is a negative value, for question 2 I do the same thing and get the same value. Do these questions have different meanings or are they both a quick way to getting easy marks?
