(A) For each half-reaction, indicate whether the reaction occurs at the cathode or the anode. Assume it is a voltaic (galvanic) cell.
(1) Sn -> Sn+2 + 2e-
(2) Cu+2 + 2e- -> Cu
(3) Zn -> Zn+2 + 2e-
(B) Indicate whether the item in the list describes a voltaic cell or a electrolytic cell.
(1) measured potential (voltage) is negative
(2) electrons flow from anode to cathode
(3) reaction is spontaneous
(4) in order to proceed as written, an external electrical current must be supplied
(5) cell potential (Ecell) is positive
