You're on a roll —
Zinc metal reacts with copper sulfate solution because zinc is more reactive than copper. In the reactivity series, zinc is placed above copper. This means zinc has a greater tendency to lose electrons and form positive ions compared to copper. When zinc metal is added to copper sulfate solution, the more reactive zinc displaces the less reactive copper from its salt solution.
The reaction forms zinc sulfate (which remains in solution) and solid copper metal (which precipitates out).
