help me answer these questions in the last picture

Taken from: Laboratory Experiments: Chemistry The Central Science, Twelfth Edition Experiment 8 Chemical Reactions To observe typical chemical reactions, identify some of the products and OBJECTIVE summarize the chemical changes in terms of balanced chemical equations.

Before an equation can be written for a reaction, someone must establish what the products are. How does that person decide what these products are? Products are identified by their chemical and physical properties as well as by analyses. That oxygen rather than chlorine gas is produced in the above reaction can be established by the fact that oxygen is a colorless, odorless gas. Chlorine, on the other hand, is a pale yellow-green gas with an irritating odor. In this experiment, you will observe that in some cases, gases are produced, precipitates are formed, or color changes occur during the reactions. These are all indications that a chemical reaction has occurred. To identify some of the products of the reactions, consult Table 8.1, which lists some of the properties of the substances that can be formed in these reactions. Reagent bottle may be labeled 6 MNHOH
