Suppose that you carefully weigh pieces of zinc and copper metal and construct a voltaic cell. After allowing the current to flow for some time, you carefully dry the pieces of metal and weigh them again. Do the pieces of metal have the same mass before and after the experiment? If not, which piece of metal gained mass, and which piece of metal lost mass? Explain your reasoning.
