What element is undergoing oxidation (if any) in the following reaction?

2 MnO^-4 (aq) + 3 NO^2- (aq) + H2O(l) ? 2 MnO^2 (s) + 3 NO^3- (aq) + 2 OH^- (aq)

These are the answer choices:

1) H

2) Mn

3) O

4) N

5) This is not an oxidation-reduction reaction

Also I need help with this one too, and I need the net Ionic equation not the complete ionic equation

Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of MgSO3 and HI are mixed.
