Resource Description
The total energy is called enthalpy. Enthalpy is the heat content or the amount of energy within a substance.
All chemical reactions are accompanied by a change in the enthalpy of the substance.
The enthalpy will either increase or decrease and therefore the symbol delta (∆) is used to represent ENTHALPY.
Change in enthalpy (∆H) can also be referred to as the heat of reaction. Therefore enthalphy calculate as follow:
