Объяснение:
1)
AgNO₃+ HCI = AgCI↓ + HNO₃
Ag⁺ + NO₃⁻ + H⁺ + CI⁻ = AgCI↓ + H⁺ + NO₃⁻
Ag⁺ + CI⁻ = AgCI↓
2)
H₂SO₄ + 2NaOH = Na₂SO₄ + 2H₂O
2H⁺ + SO₄²⁻ + 2Na⁺ + 2OH⁻ = 2Na⁺ + SO₄²⁻ + 2H₂O
OH⁻ + H⁺ = H2O
3)
CuSO₄ + 2NaOH = Cu(OH)₂ + Na₂SO₄
Cu²⁺ + SO₄²⁻ + 2Na⁺ + 2OH⁻ = Cu(OH)₂↓ + 2Na⁺ +SO₄²⁻
Cu²⁺ + 2OH⁻ = Cu(OH)₂↓
4)
K₂SO₃ + 2HNO₃ = 2KNO₃ + H₂O + SO₂
2K⁺ + SO₃²⁻+ 2H⁺ + 2NO₃⁻ = 2K⁺ + 2NO₃⁻ + H₂O + SO₂
SO₃²⁻ + 2H⁺ = H₂O + SO₂
5)
CaCl₂ + Na₂CO₃ = CaCO₃↓ + 2NaCl
Ca²⁺ + 2Cl⁻ + 2Na⁺ + CO₃²⁻ = CaCO₃↓ + 2Na⁺ + 2Cl⁻
Ca²⁺ + CO₃²⁻ = CaCO₃↓
6)
Ва(NO₃)₂ + K₂SO₄ = BaSO₄↓ + 2KNO₃
Ba²⁺ + 2NO₃⁻ + 2K⁺ + SO₄²⁻ = BaSO₄ ↓+ 2K⁺ + 2NO₃⁻
Ba²⁺ + SO₄²⁻ = BaSO₄↓
