Give examples of few metal oxides which are reduced by aluminium. Why they cannot be reduced by carbon?

Explanation

### Step-by-Step Solution:

1. **Understanding Metal Oxides**: Metal oxides are compounds formed by the reaction of metals with oxygen. Some metal oxides can be reduced to their corresponding metals by using reducing agents.

2. **Examples of Metal Oxides Reduced by Aluminium**:
- **Manganese Dioxide (MnO2)**: When manganese dioxide is heated with aluminium powder, it gets reduced to manganese metal, and aluminium oxide (Al2O3) is formed.
\[
\text{MnO}_2 + 4\text{Al} \rightarrow 2\text{Mn} + 2\text{Al}_2\text{O}_3 + \text{heat}
