Write chemical equations for the following reactions:
Manganese dioxide is heated with aluminium powder.

Explanation

To write the chemical equation for the reaction of manganese dioxide (MnO₂) with aluminum powder (Al), we will follow these steps:

### Step 1: Write the Reactants
The reactants in this reaction are manganese dioxide (MnO₂) and aluminum powder (Al). We can represent this as:
\[ \text{MnO}_2 + \text{Al} \]

### Step 2: Identify the Products
When manganese dioxide is heated with aluminum, it undergoes a reduction reaction. The products formed are aluminum oxide (Al₂O₃) and manganese (Mn). Thus, we can represent the products as:
