Объяснение:
2Al + 3H₂SO₄ = Al₂(SO₄)₃ + 3H₂
Al₂O₃ + 3SO₃ = Al₂(SO₄)₃
2Al(OH)₃ + 3Н₂SO₄ = Al₂(SO₄)₃ + 6H₂О
2)
Fe + 2HCl = FeCl₂ + H₂
FeCl₂ + 2NaOH = Fe(OH)₂ + 2NaCl
4Fe(OH)₂ + 2H₂O + O₂ = 4Fe(OH)₃
2Fe(OH)₃ =(t) = Fe₂O₃ + 3H₂О
Fe₂O₃ + 3H₂ =(t)= 2Fe + 3H₂О
2Fe + 3Cl₂ = 2FeCl₃
FeCl₃ + 3NaOH = Fe(OH)₃ + 3NaCl
2Fe(OH)₃ + 3H₂SO₄ = Fe₂(SO₄)₃ + 6H₂О
Fe₂(SO₄)₃ + 3Ba(NO₃)₂ = 3BaSO₄ + 2Fe(NO₃)₃
