Name one metal in following fitting the given description. Also, write the equation of the reaction.
A metal which is used for galvanising iron.

Explanation

### Step-by-Step Solution:

1. **Identify the Metal Used for Galvanizing Iron**:
- The metal commonly used for galvanizing iron is **Zinc**. Galvanization is a process that involves applying a protective layer of zinc to iron to prevent rusting.

2. **Explain the Process of Galvanization**:
- Galvanization is primarily done to protect iron from corrosion (rusting). The protective layer of zinc acts as a barrier between the iron and the environment, preventing moisture and oxygen from reaching the iron surface.
