Give few examples of displacement reaction.

Explanation

### Step-by-Step Text Solution

1. **Understanding Displacement Reaction**:
A displacement reaction is a type of chemical reaction where an atom or a set of atoms in a molecule is replaced or displaced by another atom. This typically occurs when a more reactive element displaces a less reactive element from its compound.

2. **Example 1: Zinc and Iron Sulfate**:
- **Reactants**: Zinc (Zn) and Iron(II) sulfate (FeSO₄).
- **Reaction**: Since zinc is more reactive than iron, it displaces iron from iron sulfate.
