WebNov 1, 2010 · Here is how I think of it. The products of the reaction are actually: Ca (OH)2 (s) + 64.8 kJ of heat If you think of it that way, then: 1. The reaction is now balanced in terms of enthalpy. Taking the +64.8kJ into account gives zero for ΔH 2. A product of the reaction is 64.8 kJ of heat (per mole), meaning that heat is given off.
