	What You'll Learn in this Lesson In this section, we focus on the energy stored within chemical bonds in the form of enthalpy. We talk about the different situations in which some reactions release heat and others absorb heat. We also talk about what Hess' Law says about enthalpy and how to use the table of enthalpies to calculate the total enthalpy change of a reaction.
