Given below is a redox reaction. Which of the following types the reaction belong to? \( \boldsymbol{C u}^{+\mathbf{2 + 6 - 2}} \boldsymbol{O}_{4(a q)}+\boldsymbol{Z} \boldsymbol{n}_{(s)} \rightarrow \boldsymbol{C u}_{(s)}+ \) \( \underset{Z n S O_{4(a q)}}{+2+6+-2} \)

1. Combination reaction
2. Decomposition reaction
3. Metal displacement reaction
4. Non-metal displacement reaction

Correct answer: Metal displacement reaction

Solution

Zinc displaces copper from copper sulfate, forming zinc sulfate and copper metal. Since one metal replaces another metal in a compound, this is a metal displacement reaction.
