Please help me solve this step by step -
Half Reactions -
NO3^-+ 4H^+ + 3e^- ---- NO + 2H2O
Fe^2+ + 2e^- ------ Fe

The equation is
NO3^-+ 4H^+ + Fe ----- NO + H2O + Fe^2+

I understand some things, but not knowing if I can add H+, should I add the electrons from the half reactions in from the start or leave until the end? As if we include from the start it unbalances the overall charge.
Also in this both the NO and Fe are being oxidised right?

In this it adds in electrons, but in mine i already have preset ones in my half reactions?
