For each of the following:
• Assign Oxidation States (Numbers) to each atom in reactants and products
• Identify the species being reduced and the species being oxidized
• Balance each redox reaction using the Half-Reaction method
O2 + ClO-2 --> H2O + ClO2
Al + MnO-4 --> MnO2 + Al(OH)-4
NO2- + Al --> NH3 + AlO2
Also could you please explain how you get the oxidation numbers, i am having trouble with that as well as to how you come up with the added electrons on the half reactions. How do you figure those numbers out?
