Объяснение:
1) Аl→ AlCl₃→ Al(NO₃)₂ → Al(OH)₃→ Al₂O₃ → Al₂(SO₃)₃
2Аl+3CI₂= 2AlCl₃
AlCl₃+3AgNO₃= Al(NO₃)₃+ 3AgCI↓
2Al(OH)₃+t°C= Al₂O₃ +3H₂O
Al₂O₃ +3H₂SO₄= Al₂(SO₃)₃ +3H₂O
2) Ba(NO₃)₂ → HNO₃ → Mg(NO₃)₂→- Mg(OH)₂→ MgO → MgCl₂
Ba(NO₃)₂+ H₂SO₄ = 2HNO₃+BaSO₄↓
2HNO₃+MgO = Mg(NO₃)₂+H₂O
Mg(NO₃)₂+2NaOH= Mg(OH)₂↓+2NaNO₃
Mg(OH)₂+t°C= MgO+H₂O
MgO +2HCI= MgCl₂+H₂O
