Hydrogen is a good reducing agent. It reduces metallic oxides into metals. (True / False)

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement we need to evaluate is whether hydrogen is a good reducing agent and if it can reduce metallic oxides into metals.

2. **Definition of Reducing Agent**: A reducing agent is a substance that donates electrons to another substance, causing the other substance to be reduced. In the process, the reducing agent itself is oxidized.

3. **Example of Reduction**: Let's consider a specific example: copper(II) oxide (CuO). When hydrogen gas (H₂) reacts with copper(II) oxide, it can reduce CuO to copper (Cu) by removing the oxygen from the oxide.
