A voltaic cell is constructed from a standard Cu2+Cu half cell (E red =0.337V) and a standard Al3+Al3 half cell (E red = 1.660V) (Use the lowest possible coefficients. Be sure 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 spontaneous cell reaction is: The cell voltage is V. A voltaic cell is constructed from a standard Cu2+Cu half cell ( E red =0.337V ) and a standard Cl2Clhalf cell (E red =1.360 V). (Use the lowest possible coefficients, Be sure 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 spontaneous cell reaction is: The cell voltage is V. A voltaic cell is constructed from a standard H+H2 half cell (E red =0.000V) and a standard F2Fhalf cell ( E red =2.870V ). (Use the lowest possible coefficients. Be sure to specify states such as (aq) or ( ( ). If a box is not needed, leave it blank.) The anode reaction is: The cathode reaction is: The spontaneous cell reaction is
