Объяснение:
Сu(NO₃)₂ + 2NaOH = Cu(OH)₂↓ + 2NaNO₃
Cu²⁺+2NO₃⁻ + 2Na⁺+2OH⁻ = Cu(OH)₂↓ + 2Na + 2NO₃⁻
Cu²⁺ + 2OH⁻ = Cu(OH)₂↓
Cu(OH)₂ + H₂SO₄ = CuSO₄ + 2H₂O
Cu(OH)₂ + 2H⁺ + SO₄²⁻ = Cu²⁺ + SO₄²⁻ + 2H₂O
Cu(OH)₂ + 2H⁺ = Cu²⁺ + 2H₂O
CuSO₄ + BaCl₂ = CuCl₂ + BaSO₄↓
Cu²⁺ + SO₄²⁻ + Ba²⁺ + 2Cl⁻ = Cu²⁺ + 2Cl⁻ + BaSO₄↓
Ba²⁺ + SO₄²⁻ = BaSO₄↓
