I completed the experiment. I just need help with the "Determinations." Thanks

DATA ANALYSIS & DISCUSSION DETERMINATIONS For each observed reaction, identify the products. Determine the oxidation numbers. From the change in oxidation numbers, identify the species being reduced, the species being oxidized, the oxidizing agent, and the reducing agent. Produce a Summary Table similar to the one that follows with two of the reactions started. This will help you figure out what is being oxidized and reduced, and also what the oxidizing and reducing agents are.
