Watch Episode #12:

                11. The Mole
                 Using Avogadro's law, the mass of a substance can be related to the number of particles contained in that mass
                 13. The Driving Forces

                  Endothermic and exothermic reactions are investigated and the role of entropy is revealed.

                 VOD14. Molecules in Action
                 Observing molecules during chemical reactions helps explain the role of catalysts. Dynamic equilibrium is also demonstrated
