(1) Al₂(SO₄)₃ + 3BaCl₂ → 3BaSO₄ + 2AlCl₃; Type of reaction: Double displacement
(2) Al₂S₃ → 2Al + 3S; Type of reaction: Decomposition
(3) 6NaOH + CuSO₄ → Na₂SO₄ + Cu(OH)₂ (Note: The product Na₃PO₄ is incorrect for this reaction. Assuming typo, corrected to Na₂SO₄); Type of reaction: Double displacement
(4) Fe + H₂SO₄ → FeSO₄ + H₂ (Note: Product Fe₂SO₄ is incorrect. Assuming typo, corrected to FeSO₄); Type of reaction: Single displacement
(5) C₄H₁₂ + O₂ → 4CO₂ + 6H₂O (Note: C₄H₁₂ is not a standard hydrocarbon. Assuming typo for C₄H₁₀ or similar. For C₄H₁₀: 2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O); Type of reaction: Combustion
(6) 2H₂S + 3O₂ → 2SO₂ + 2H₂O; Type of reaction: Combustion
(7) C₅H₉O + O₂ → 5CO₂ + 4.5H₂O (Note: C₅H₉O is unusual. Balanced as written: 2C₅H₉O + 13O₂ → 10CO₂ + 9H₂O); Type of reaction: Combustion
(8) 2Al + 3NiBr₂ → 2AlBr₃ + 3Ni; Type of reaction: Single displacement
(9) 4Al + 3O₂ → 2Al₂O₃; Type of reaction: Synthesis
(10) 2H₂O₂ → 2H₂O + O₂; Type of reaction: Decomposition
(11) 2K + Cl₂ → 2KCl; Type of reaction: Synthesis
(12) 2Na + MgCl₂ → 2NaCl + Mg; Type of reaction: Single displacement
