Question

Enter electrons as e A voltaic cell is constructed in which the anode is a Sn Sn2 half cell and the cathode is a Cu Cu compartments are connected by a salt bridge. half cell. The half-cell (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: The cathode reaction is: The net cell reaction is: the Sn Sn2 electrode the Cu Cu electrode In the external circuit, electrons migrate the Cu Cu the Sn Sn In the salt bridge, anions migrate compartment. compartment|
