1. A voltaic cell is constructed in which the anode is a Mn|Mn2+ half cell and the cathode is a Cu|Cu2+ half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: (aq)(s)(l)(g) + (aq)(s)(l)(g) ----> (aq)(s)(l)(g) + (aq)(s)(l)(g) The cathode reaction is: (aq)(s)(l)(g) + (aq)(s)(l)(g) -----> (aq)(s)(l)(g) + (aq)(s)(l)(g)...
