Ответ:
2Al + 3H₂SO₄ = Al₂(SO₄)₃ + 3H₂
Al₂(SO₄)₃ + 6KOH = 2Al(OH)₃ + 3K₂SO₄
2Al(OH)₃ + 3H₂SO₄ = Al₂(SO₄)₃ + 6H₂O
K₂O + H₂O = 2KOH
2KOH + SO₃ = K₂SO₄ + H₂O
K₂SO₄ + BaCl₂ = 2KCl + BaSO₄
S + O₂ = SO₂
SO₂ + 2KOH= K₂SO₃ + H₂O
K₂SO₃ + Fe(NO₃)₂ = 2KNO₃ + FeSO₃
FeSO₃ + 2NaOH = Fe(OH)₂ + Na₂SO₃
Fe(OH)₂ = FeO + H₂O
