Using the half-equation method, balance the following redox half-equations in an acidic solution and state if each halfequation is either oxidation or reduction. To balance a half-equation with polyatomic ions: Step 1: Balance atoms other than oxygen and hydrogen Step 2: Balance oxygen by adding water $$\left({\mathrm{H}}_2\mathrm{O}\right)$$ Step 3: Balance hydrogen by adding $${\mathrm{H}}^{+}(\mathrm{aq})$$ Step 4: Balance the charge by adding $${\mathrm{e}}^{?}$$to the more positive side
