Объяснение:
1)
Na₂CO₃ + 2HCl = 2NaCl + H₂O + CO₂↑
2Na⁺ + CO3²⁻ + 2H⁺ + 2Cl⁻ = 2Na⁺ + 2Cl⁻ + H₂O + CO₂↑
CO3²⁻ + 2H⁺ = H₂O + CO₂↑
2)
FeCl₃ + 3NaOH → Fe(OH)₃↓ + 3NaCl
Fe³⁺ + 3Cl− + 3Na⁺ + 3OH⁻ = Fe(OH)₃↓ + 3Na⁺ + 3Cl⁻
Fe³⁺ + 3OH⁻ = Fe(OH)₃↓
3)
H₂SO₄ + 2LiOH = Li₂SO₄ + 2H₂O
2H⁺ + SO₄²⁻ + 2Li⁺ + 2OH⁻ = 2Li⁺ + SO₄²⁻+ 2H₂O
H⁺ + OH⁻ = H₂O
