Answer
See explanation below.
Work Step by Step
a. Copper is coating the iron.
b. Oxidizing agent is Cu2+ and the reducing agent is Fe.
c. Yes, as the reaction is being spontaneous, this can be made into a voltaic cell.
d. Cu2+(aq) + Fe(s) → Cu(s) + Fe2+(aq)
e. E cell = E°Cu2+ - E°Fe2+
= 0.34 V - (-0.44 V)
= 0.78 V
