Give the chemical reaction in which dihydrogen acts as an oxidising agent.

Explanation

To determine a chemical reaction in which dihydrogen (H₂) acts as an oxidizing agent, we can follow these steps:

### Step 1: Understand the Definitions
- **Dihydrogen (H₂)**: This is the molecular form of hydrogen, consisting of two hydrogen atoms.
- **Oxidizing Agent**: An oxidizing agent is a substance that causes another substance to be oxidized (lose electrons) while itself being reduced (gaining electrons).

### Step 2: Identify the Reaction
We need to find a chemical reaction where dihydrogen acts as an oxidizing agent. A well-known reaction is:
