Reaction Yields
This lecture discusses how to compute the yield of a chemical reaction by using the molar masses of reactants and products.
This lecture talks about the ideal gas law, PV=nRT, the kinetic theory of gases, and a little bit about the properties of real (non-ideal) gases.

This lecture introduces several different types of energy, including heat and enthalpy. We discuss the First Law of Thermodynamics and how to calculate the enthalpy change for a chemical reaction.
