Enter electrons as e-. A voltaic cell is constructed from a standard Al3+ | Al half cell (EĀ°red = -1.660V) and a standard Fe3+ | Fe2+ half cell (EĀ°red = 0.771V). (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.

Enter electrons as e-. Use smallest possible integer coefficients. If a box is not needed, leave it blank. Use the table 'Standard Reduction Potentials' located in the 'Tables', to predict if a reaction will occur when Zn metal is put into a 1M aqueous Al3+ solution. If a reaction will occur, write a balanced net ionic equation for the reaction. If no reaction will occur, leave all boxes blank.

Enter electrons as e-. Use smallest possible integer coefficients. If a box is not needed, leave it blank. Use the table 'Standard Reduction Potentials' located in the 'Tables', to predict if a reaction will occur between Hg metal and I2(s), when the two are brought in contact via half-cells in a voltaic cell. If a reaction will occur, write a balanced net ionic equation for the reaction, assuming that the product ions are in aqueous solution. If no reaction will occur, leave all boxes blank.

Enter electrons as e-. Use smallest possible integer coefficients for ALL reactions. If a box is not needed, leave it blank. A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge. Co2+(aq) + 2Cr2+(aq) -> Co(s) + 2Cr3+(aq) The anode reaction is: The cathode reaction is: In the external circuit, electrons migrate the Cr2+|Cr3+ electrode the Co|Co2+ electrode. In the salt bridge, anions migrate the Co|Co2+ compartment the Cr2+|Cr3+ compartment.
