Объяснение:
а) Fe → FeCl₃ → Fe(OH₃ → F₂O₃ → Fe(NO₃)₃
2Fe+3CI₂= 2FeCl₃
FeCl₃+3NaOH= Fe(OH)₃↓+3NaCO
2Fe(OH)₃+t°C = F₂O₃+3H₂O
F₂O₃+6HNO₃= 2Fe(NO₃)₃++3H₂O
б) Fe → FeCl₂ → Fe(OH)₂ → Fe(OH)₃ → Fe₂(SO₄)₃
Fe+2HCI= FeCl₂+H₂↑
FeCl₂ +2NaOH= Fe(OH)₂↓+2NaCI
4Fe(OH)₂ + 2H₂O + O₂ = 4Fe(OH)₃↓
2Fe(OH)₃+3H₂SO₄ = Fe₂(SO₄)₃+6H₂O
