For the following chemical reaction, do the following:
Show all the oxidation of each "atom" above it.
Make the appropriate brackets with Reactant oxidation number ---> product oxidation number, then "lose or gain e- and (actual number and the ( ) showing # of electron lost/gain to whole substance for balancing purposes)
Make sure that one bracket is above chemical equation and another below
Then write down (as described in notes) what is oxidized, reduced, oxidizing agent, reducing agent.
If no oxidation numbers are changing from reactant to product, write NOT REDOX RXN (but must show oxidization numbers)
Balance the chemical reaction (show the initial coefficient for electron to balance and then cross out if need more reactant to balance atoms
