Give balanced chemical equations for the following reactions :
Hydrogen sulphide treated with concentrated sulphuric acid.

Explanation

To balance the chemical equation for the reaction of hydrogen sulfide (H₂S) with concentrated sulfuric acid (H₂SO₄), we follow these steps:

### Step 1: Write the unbalanced equation
The reactants are hydrogen sulfide (H₂S) and concentrated sulfuric acid (H₂SO₄). The products of the reaction are sulfur (S) and water (H₂O). The unbalanced equation can be written as:
\[ \text{H}_2\text{S} + \text{H}_2\text{SO}_4 \rightarrow \text{S} + \text{H}_2\text{O} \]

### Step 2: Identify the products
From the reaction, we know that hydrogen sulfide reacts with sulfuric acid to produce sulfur (S) and water (H₂O). The balanced equation will also produce sulfur dioxide (SO₂) as a product.
