In this clip I do several problems on a comprehensive final exam. The first is our standard first problem where we must predict the products of a particular chemical reaction, identify the phase of each product and balance the equation. The second problem I write the ionic and net ionic equation for one of the reactions in question 1. The 3rd question is a complicated conversion problem. The final question on this part consists of three essay questions; one on ionization energy, a second on the hydrogen atom and a third on polarity of molecules.
