Question

The above reaction is an example of a: \[ \text{Zn} + \text{CuSO}_4 \rightarrow \text{ZnSO}_4 + \text{Cu} \]

• A. Combination reaction
• B. Displacement reaction
• C. Double displacement reaction
• D. Decomposition reaction

Hint:

A displacement reaction occurs when a more reactive metal replaces a less reactive metal in a compound.

Answer 1

The Correct Option is B

Step 1: Understanding displacement reactions. In a displacement reaction, a more reactive element replaces a less reactive element from its compound. Here, zinc (\text{Zn}) is more reactive than copper (\text{Cu}), so it displaces copper from copper sulfate (\text{CuSO}_4) to form zinc sulfate (\text{ZnSO}_4).
Step 2: Explanation of incorrect options.
- Combination reaction: This involves two or more reactants combining to form a single product.
- Double displacement reaction: Involves the exchange of ions between two compounds.
- Decomposition reaction: A single compound breaks down into simpler substances.
