Enter electrons as e Use smallest possible integer coefficients for ALL reactions. If a box is not needed, leave it blank. A voltaic electrochemical cell is constructed in which the anode is a Mg2+1 Mg half cell and the cathode is a Cl2 ci half cell. The half-cell compartments are connected by a salt bridge. Write the anode reaction. + + Write the cathode reaction. + Write the net cell reaction. + + In the external circuit, electrons migrate the Mg2+ Mg electrode the Cl2lci electrode. In the salt bridge, anions migrate the Mg2+1 Mg compartment the cl2lci compartment
