3. A galvanic displacement is now happening between Zn?*/Zn (E°=-0.76V) and Cu2+/Cu (E°=0.34V). Which one is dissolved and which one is deposited? If 30g of Zn is reacting during 1min, how much mole of Cu is responding? How much of current (in mA) is flowing? (mass number : Zn 65.41amu, Cu 63.55amu)
