Label the anode and cathode, indicate the direction of electron flow and the species present in each solution for each of the following overall redox reactions.
1) Ni2+(aq)+Mg(s)→Ni(s)+Mg2+(aq)
2) 2H+(aq)+Fe(s)→H2(g)+Fe2+(aq)
3) 2NO-3(aq)+8H+(aq)+3Cu(s)→2NO(g)+4H2O(l)+3Cu2+(aq)
Then Indicate the half-reaction occurring at each Anode then cathode , Express your answers as a chemical equation. Identify all of the phases in your answers.
