Name one metal in following fitting the given description. Also, write the equation of the reaction.
The metal reacts slowly with dil. HCl and dil. `H_2SO_4` to produce hydrogen but the salts formed by the reaction are insoluble and thus form a coating over the metal that prevents the contact between the metal and the acid and the reaction stops.

Explanation

To solve the question, we need to identify a metal that reacts slowly with dilute hydrochloric acid (HCl) and dilute sulfuric acid (H2SO4) to produce hydrogen gas, while also forming insoluble salts that coat the metal and stop the reaction.

### Step-by-Step Solution:

1. **Identify the Metal**:
- The metal that fits the description is **Lead (Pb)**. Lead reacts slowly with both dilute HCl and dilute H2SO4.

2. **Write the Reaction with Dilute HCl**:
