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?
