In a chemistry lab, as an exercise, you must plate a layer of copper over a piece of metal having an area of . To do the job you connect a battery between a copper anode and the piece of metal to be coated which sits in a copper sulfate bath. Each Cu ion has a deficit of 2 electrons. Assuming a current of 3 ?A is measured for 1 hour. How thick is the copper coating? Picture diagram would be greatly appreciated.
