A galvanic (voltaic) cell contains a copper cathode immersed in a copper(II) chloride solution and a nickel anode immersed in a nickel(II) chloride solution. The two solutions are connected with a salt bridge. 1. Write the balanced equation for the galvanic cell. Phases are optional. 2. A current of 1.61 A is observed flowing through the cell for a period of 1.16 h. Calculate the amount of charge flowing through the circuit during this time. 3.Calculate the number of moles of electrons flowing through the circuit during this time.
