What is the thermochemical equation?

It is a balanced of stoichiometric chemical equation that involved the change with respect to enthalpy, ΔH. Here the reactants and the product state should be considered as the liquid, solid, or in gaseous state.

Also, the value of the heat should be absorbed since ΔH < 0 so the reaction should be considered as the exothermic and ΔH > 0 then the reaction is endothermic.
