The chemical equation Al + H2SO4 -> Al2(SO4)3 + H2

1. Detailed information about the Al + H₂SO₄ -> Al₂(SO₄)₃ + H₂equation:

This equation describes the reaction between aluminum (Al) and concentrated, hot sulfuric acid (H₂SO₄) to produce aluminum sulfate (Al₂(SO₄)₃) and hydrogen gas (H₂).

However, this equation is not yet balanced. The balanced equation would be:

2Al + 3H₂SO₄ -> Al₂(SO₄)₃ + 3H₂

2. Reaction conditions:
   This reaction occurs when aluminum comes into contact with concentrated and hot sulfuric acid.

3. The reaction process:

When aluminum comes into contact with concentrated, hot sulfuric acid, it reacts with the acid to form aluminum sulfate (a type of salt) and hydrogen gas. The hydrogen gas will escape from the solution.

4. Observations:
   When aluminum is placed in concentrated, hot sulfuric acid, you will see bubbles start to escape from the solution. This is the hydrogen gas produced during the reaction. Simultaneously, the aluminum gradually gets consumed until it is completely dissolved in the solution.
