Part IV Oxidation Reduction Reaction (Redox reactions)

Answer the following Redox reaction as stated in the following:

• If you have a Redox reaction, then do work to show species that is oxidized, is reduced, and oxidizing agent and reducing agent.
• If you do not have a Redox reaction, show how all oxidation numbers for each species does not change from reactant to product and then write a sentence explaining.
• Balance all the following Redox reaction even if the reaction does not occur.
