Question

When you balance a redox equation using the half-reaction method, what do you do after you write the oxidation and reduction half-reactions?

Answer 1

For each half reaction:
>Balance all except O and H
>Balance O using H2O
>balance H using H+
>balance charge using e-
Then multiply the half reactions to balance the e-
Add them back together

Answer 2

Use a coefficient to make the number of electrons lost equal the number of electrons gained
