Use the activity series to predict the half-reaction that occurs at the anode and the half-reaction that occurs at the cathode of a voltaic cell for the following combination of half-reactions. [The notation Zn(s)/Zn2+(aq) used below indicates the components of one of the half cells: Zn metal electrode placed in an aqueous solution ofZn2+.]
