Zn+Ag2O = ZnO+Ag Write both half reactions in basic environment and find Eo from silver and Zn half cells by looking up Eocell. Write out Nerst equation for both half cells (find E)Predict how the voltage of the battery will change as the starting concentrations decrease. Draw the galvonic cell for the reaction. Thank you.

Answer #1

Overall equation = . Zinc is the anode and silver oxide is the cathode.

As the starting concentrations, tend to decrease, silver will start getting deposited and the concentration of zinc ions will increase.
