Sketch a voltaic cell for the overall reaction given below. On your sketch: (a) Label the anode and cathode. (b) Indicate the half-reaction occurring at each electrode and the species present in each solution. (c) Indicate the direction of electron flow. 2 NO^-_3 (aq) + 8 H^+ (aq) + 3 Cu (s) rightarrow 2 NO (g) + 4 H_2O (l) + 3 Cu^2+ (aq) How would you represent this voltaic cell using line notation?
