Hess's law

Hess's law was made by G.H Hess, and through it he found out when 2 or more chemical reactions became one, the heat of reaction also became one. He made up his law by using the first law of thermodynamics, which is a saying about the law of conservation being able to be added to chemical reactions. Sometimes they may disappear entirely if it is on different sides of the reactions by itself.
