Assume that you want to construct a voltaic cell that uses the following half-reactions:

You begin with the incomplete cell pictured here in which the electrodes are immersed in water.

(a) What additions must you make to the cell for it to generate a standard emf?
(b) Which electrode functions as the cathode?
(c) Which direction do electrons move through the external circuit?
(d) What voltage will the cell generate under standard conditions?
