Answers

When aluminum (Al) reacts with water (H₂O), especially in the presence of an acid or heat, it typically produces aluminum hydroxide (Al(OH)₃) and hydrogen gas (H₂). The balanced equation for this reaction is:
\[
2 \, \text{Al} + 6 \, \text{H}_2\text{O} \rightarrow 2 \, \text{Al(OH)}_3 + 3 \, \text{H}_2
\]
In most cases, however, aluminum is protected by a thin layer of aluminum oxide (Al₂O₃) that prevents it from reacting vigorously with water at room temperature. Under certain conditions (e.g., with heat or in alkaline solutions), the reaction can occur more readily.
