Write one chemical equation that conc. `H_2SO_4` is a strong oxidising agent.

Explanation

To demonstrate that concentrated sulfuric acid (H₂SO₄) acts as a strong oxidizing agent, we can write the following chemical equation involving carbon (C) as a reactant:

### Step-by-Step Solution:

1. **Identify the Reactants**: We will use carbon (C) as the element that will be oxidized by concentrated sulfuric acid (H₂SO₄).

2. **Understand the Reaction**: When carbon reacts with concentrated sulfuric acid, it gets oxidized to carbon dioxide (CO₂). The sulfuric acid, in turn, is reduced to sulfur dioxide (SO₂) and water (H₂O).
