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. Write the balanced equation for the galvanic cell. Phases are optional. balanced equation: A current of 1.55 A is observed flowing through the cell a period of 1.26 h. Calculate the amount of charge flowing through the circuit during this time. q= C Calculate the number of moles of electrons flowing through the circuit during this time. moles of electrons: Calculate the mass change in grams of the copper and nickel electrodes. mass change of copper electrode: mass change of nickel electrode: g g
