Solution: Indicate the half-reaction occurring at Anode and the half-reaction occurring at Cathode of the following:  a. Ni2+(aq)+Mg(s) → Ni(s)+Mg2+(aq)b. 2H+(aq)+Fe(s) → H2(g)+Fe2+(aq)c. 2NO3-(aq)+8H+(aq)+3Cu(s) → 2NO(g)+4H2O(l)+3Cu2+(aq)

Solution: Indicate the half-reaction occurring at Anode and the half-reaction occurring at Cathode of the following: a. Ni2+(aq)+Mg(s) → Ni(s)+Mg2+(aq)b. 2H+(aq)+Fe(s) → H2(g)+Fe2+(aq)c. 2NO3-(aq)+8H+(aq)+3Cu(s

Problem
