Answer 2

The given chemical equation is:

MnO₂ + H² → Al + Cl₂ → KOH + H₂SO₄ → Al₂S₃ → Ba + O₂

Let's break down the equation step by step:

1. MnO₂ + H² → Al + Cl₂: - In this step, manganese dioxide (MnO₂) reacts with hydrogen gas (H²) to produce aluminum (Al) and chlorine gas (Cl₂). - The balanced equation for this reaction is: 2MnO₂ + 4H² → 2Al + 2Cl₂. - This reaction involves the reduction of MnO₂ and the oxidation of H².

2. Al + Cl₂ → KOH + H₂SO₄: - In this step, aluminum (Al) reacts with chlorine gas (Cl₂) to produce potassium hydroxide (KOH) and sulfuric acid (H₂SO₄). - The balanced equation for this reaction is: 2Al + 3Cl₂ → 2KOH + H₂SO₄. - This reaction involves the displacement of chlorine by aluminum.

3. KOH + H₂SO₄ → Al₂S₃: - In this step, potassium hydroxide (KOH) reacts with sulfuric acid (H₂SO₄) to produce aluminum sulfide (Al₂S₃). - The balanced equation for this reaction is: 6KOH + 3H₂SO₄ → Al₂S₃ + 3H₂O + 3K₂SO₄. - This reaction involves the neutralization of KOH and H₂SO₄.

4. Al₂S₃ → Ba + O₂: - In this step, aluminum sulfide (Al₂S₃) decomposes to produce barium (Ba) and oxygen gas (O₂). - The balanced equation for this reaction is: Al₂S₃ → 2Al + 3S. - This reaction involves the decomposition of Al₂S₃.

Please note that the given chemical equation is a combination of multiple reactions, and it is important to balance each individual reaction to obtain the correct stoichiometry.
