Specify which of the following are oxidation-reduction reactions, and identify the oxidizing agent, the reducing agent, the substance being oxidized, and the substance being reduced. (Type your answer using the format [Ca]2+ for Ca2+. If the reaction is not an oxidation-reduction reaction, type none in the answer boxes for the oxidizing agent, the reducing agent, the substance being oxidized, and the substance being reduced.)
