Enthalpy (also known as the heat of reaction) is used to quantify the total heat of a system. When a chemical reaction occurs, the enthalpy of a system changes. An increase in enthalpy (heat entering the system) is ...
What is enthalpy of combustion? How does a combustion reaction differ from other chemical reactions? Are combustion reactions exothermic? What's the balanced chemical equation for the combustion of carbon? What is a chemical reaction? What is the heat of a reaction?
