Examples of enthalpy changes include enthalpy of combustion, enthalpy of fusion, enthalpy of vaporization, and standard enthalpy of formation. If the enthalpies of formation are available for the reactants and products of a reaction, the enthalpy change can be calculated using Hess’s law.

It defines empirical formulas as the simplest whole-number ratios of elements and distinguishes them from molecular formulas. The process involves elemental analysis, including converting percentages to grams, calculating moles, and finding whole-number ratios. An example of iron and oxygen is given, resulting in the formula Fe2O3.
