have deposited somewhere else in the electroplating apparatus c)
have radioactively decayed d) a) or b)
7. If the other metal gains more mass than the Cu metal loses,
the extra mass of Cu could a) have come from the CuSO4(aq) solution
b) have been created from electrical energy c) both of these d)
none of these
