Объяснение:
1)
Ba(OH)₂ + 2HNO₃ = Ba(NO₃)₂ + 2H₂O
Ba²⁺ + 2OH⁻ + 2H⁺ + 2NO₃⁻ = Ba²⁺ + 2NO₃⁻ + 2H₂O
H⁺ + OH⁻ = H₂O
2)
2Al(OH)₃+ 3H₂SO₄ = Al₂(SO₄)₃ + 6H2O
2Al(OH)₃ + 6H⁺ + 3SO₄²⁻= 2Al³⁺ + 3SO₄²⁻ + 6H₂O
Al(OH)₃ + 3H⁺ = Al³⁺ + 3H₂O
3)
FeCl₂ + 2KOH = Fe(OH)₂↓ + 2KCl
Fe²⁺ + 2Cl⁻ + 2K⁺ + 2OH⁻ = Fe(OH)₂↓ + 2K⁺ + 2Cl⁻
Fe²⁺ + 2OH⁻ = Fe(OH)₂↓
4)
Na₂CO₃ + 2HCl = 2NaCl + H₂O+ CO₂
2Na⁺ + CO₃²⁻ + 2H⁺ + 2Cl⁻ = 2Na⁺ + 2Cl⁻ + H₂O + CO₂
CO₃²⁻ + 2H⁺ = H₂O+ CO₂
5)
2K₃PO₄ + 3Zn(NO₃)₂ = Zn₃(PO₄)₂ + 6KNO₃
6K⁺ + 2PO₄³⁻ + 3Zn²⁺ + 6NO₃⁻ = Zn₃(PO₄)₂ + 6K⁺ + 6NO₃⁻
3Zn²⁺ + 2PO₄³⁻ = Zn₃(PO₄)₂
