In this segment I did a number of problems from a past Exam #2. I began by doing a problem where the products of several reactions had to be predicted. The second problem the ionic and net ionic equation was written for two of the reactions discussed in the first problem. Next we did one of my favorite problems converting from grams to mol using molar mass and finding the number of molecules or formula units using Avogadro's Number. Then we looked at a challenging combustion analysis problem for determining empirical formulas. An interesting problem that combined stoichiometry and concentration. The last problem was a limiting reagent problem.
