It is important in processes involving coal or coke where knowledge about heat of reactions is essential. Based on the fact that mass and energy are conserved in chemical reactions, it allows enthalpy change to be found for reactions that can't be measured easily. For ten points, name this principle stating that if a reaction is the sum of two or more other reactions, the enthalpy change for the overall process is the sum of the enthalpy changes for the constituent react
