Write balanced chemical equations for the following reaction
Reaction of aluminium powder with hot and concentrated caustic soda solution

Explanation

To write the balanced chemical equation for the reaction of aluminum powder with hot and concentrated caustic soda solution, follow these steps:

### Step 1: Identify the Reactants
- The reactants in this reaction are aluminum powder (Al) and caustic soda (sodium hydroxide, NaOH). Since the reaction occurs in a hot and concentrated solution, we will also consider water (H2O) as a reactant.

### Step 2: Write the Unbalanced Equation
- The unbalanced equation can be written as:
\[
