Given the cell notation of \( \mathrm{Cu}_{(\mathrm{s})}{\mathrm{e} C u^{2+}}_{(\mathrm{aq})}(1 \mathrm{M}) \hat{\mathrm{e} e } \mathrm{Zn}^{2+}{ }_{(\mathrm{aq})}(1 \mathrm{M}) \hat{\mathrm{e} Z \mathrm{Zn}}(\mathrm{s}) \), as the reaction in this cell takes place, the mass of the copper electrode Increases Decreases then increases Increases then decreases Stays the same Decreases
