The difference between the heat content of the products and the heat content of the reactants is?

The difference between the heat content of the products and the heat content of the reactants is heat of a reaction

Explanation:

The Heat of Reaction (also known and Enthalpy of Reaction) is the change in the enthalpy of a chemical reaction that occurs at a constant pressure. Enthalpy is important because it tells us how much heat (energy) is in a system. Three factors can affect the enthalpy of reaction: The concentrations of the reactants and the products. The temperature of the system. The partial pressures of the gases involved Heat is important because we can extract useful work from it. In terms of a chemical reaction, an enthalpy change tells us how much enthalpy was lost or gained, enthalpy meaning the heat energy of the system. It is a thermodynamic unit of measurement useful for calculating the amount of energy per mole either released or produced in a reaction. A negative enthalpy represents an exothermic reaction, releasing heat. A reaction that absorbs heat is endothermic. Its enthalpy will be positive, and it will cool down its surroundings. This reaction is exothermic.
