For each of the following equations, determine the oxidationnumber for each atom in the equation and identify whether thereaction is a redox reaction or not. If the reaction is redox,identify what is oxidized, what is reduced, the oxidizing agent,and the reducing agent. (Enter your answer using the format +1 and-2. Enter NONE in any unused answer blanks.)
