Question

Осуществить генетический ряд:
1)Al-Al2(SO4)3-Al(OH)3-Al2O3-AlCl3
2)Mg-MgCl2-Mg(OH)2-MgSO4-MgCO3-MgO
3)Fe-FeCl2-Fe(OH)-FeO-Fe-FeCl3-Fe(OH)3-Fe2O3-Fe​

Answer 1

Ответ:

1)Al→Al2(SO4)3→Al(OH)3→Al2O3→AlCl3

2Al+3H₂SO₄=Al₂(SO₄)₃+3H₂

Al₂(SO₄)₃+6NaOH=2Al(OH)₃+3Na₂SO₄

2Al(OH)₃+t°C=Al₂O₃+3H₂O

Al₂O₃+6HCI=2AlCl₃+3H₂O

2)Mg→MgCl2→Mg(OH)2→MgSO4→MgCO3→MgO

Mg+2HCI=MgCl₂+H₂O

MgCl₂+2NaOH=Mg(OH)₂+2NaCI

Mg(OH)₂+H₂SO₄=MgSO₄+2H₂O

MgSO₄+Na₂CO₃=MgCO₃+Na₂SO₄

MgCO₃+t°C=MgO+CO₂

3)Fe→FeCl2→Fe(OH)2→FeO→Fe→FeCl3→Fe(OH)3→Fe2O3→Fe​

Fe+2HCI=FeCl₂+H₂

FeCl₂+2NaOH=Fe(OH)₂+2NaCI

Fe(OH)₂+t°C=FeO+H₂O

FeO+H₂=Fe+H₂O

2Fe+3CI₂=2FeCl₃

FeCl₃+3NaOH=Fe(OH)₃+3NaCI

2Fe(OH)₃+t°C=Fe₂O₃+3H₂O

2Fe₂O₃+3C=2Fe​+3CO₂
