Which metal is used for reducing `Cr_(2)O_(3)` and `Mo_(2)O_(3)` to metal ?

Explanation

To determine which metal is used for reducing \( \text{Cr}_2\text{O}_3 \) and \( \text{Mo}_2\text{O}_3 \) to their respective metals, we can follow these steps:

### Step 1: Identify the Reduction Process
Reduction is a chemical process where a substance gains electrons or decreases its oxidation state. In this context, we are looking for a reducing agent that can convert the metal oxides \( \text{Cr}_2\text{O}_3 \) and \( \text{Mo}_2\text{O}_3 \) into their elemental forms.

**Hint:** Think about common reducing agents used in metallurgy.
