Answer:

BEACUSE COPPER LESS REACTIVE THAN ZINC

Explanation:

One familiar reaction is that of zinc and copper sulfate. Zinc metal is above copper in the activity series and therefore, zinc will replace copper in solution. The zinc metal is being oxidized as it loses electrons, and the copper(II) ions are reduced to copper metal as they acquire electrons.
