Heat Released

I know that if heat is released, q is negative. If the question asks for how much heat was released to we still put the negative sign on the number of Joules or calories?

i believe you would say the amount you found in positive, followed by the word released. for example, -55 kJ could be answered as 55 kJ released. hope that helps!

Yeah like nicole said, it depends on how you word the answer. If you add the word released then your number is positive, but if you are referring to the change in energy for the reaction then it should be negative
