Answer 2

The balanced chemical equation for the reaction between aluminum (Al) and water (H2O) to form aluminum hydroxide (Al(OH)3) and hydrogen gas (H2) is as follows:

2 Al + 6 H2O -> 2 Al(OH)3 + 3 H2

In this balanced equation:

• On the left side, we have 2 moles of aluminum (Al) reacting with 6 moles of water (H2O).
• On the right side, we get 2 moles of aluminum hydroxide (Al(OH)3) and 3 moles of hydrogen gas (H2).

The equation is balanced as the number of atoms of each element on both sides of the reaction arrow is the same.
