Your classmate is correct because the reaction between zinc (Zn) and copper sulfate (CuSO4) is indeed an example of a redox reaction that can occur in a galvanic cell. In this reaction, zinc is oxidized, losing electrons and forming zinc sulfate (ZnSO4), while copper ions (Cu²⁺) in the copper sulfate solution are reduced, gaining electrons to form solid copper (Cu). This transfer of electrons produces a flow of electric current, which is the fundamental principle behind a galvanic cell. The potential difference between the two half-cells featuring zinc and copper allows for the spontaneous reaction to occur, generating electrical energy as a result.
Zn + CuSO4 > ZnSO4 + Cu.
Zinc reactions with copper sulfate to form zinc sulfate and copper. A classmate tell you this is a reaction in a galvanic cell. In three to five sentences describe how you know your classmate is correct
