Объяснение:
1. Ca(OH)2, NaOH, Al(OH)3, KOH, Fe(OH)2, Ba(OH)2, Cu(OH)2
2. RbOH, KOH, LiOH
Cu(NO₃)₂ + 2RbOH = Cu(OH)₂↓ + 2RbNO₃
Cu(NO₃)₂ + 2KOH = Cu(OH)₂↓ + 2KNO₃
Cu(NO₃)₂ + 2LiOH = Cu(OH)₂↓ + 2LiNO₃
3. Ba(OH)₂ + H₂SO₄ = BaSO₄↓ + 2H₂O
Ba(OH)₂ + KOH≠
Ba(OH)₂ + BaO≠
Ba(OH)₂ + Fe≠
Ba(OH)₂ + Fe(NO₃)₂ = Fe(OH)₂↓ + BaNO₃
