I just didn't know the fact that the sums of the heat capacities would equal 0. Is there a specific reason why?
Yes. We makes the assumption that no energy in the form of heat is lost or gained by the system, that it is perfectly insulated. This means the total energy in the form of heat can not change magnitude.
