Объяснение:

а)

FeCl₃ + 3KOH = Fe(OH)₃↓ + 3KCl

Fe³⁺ + 3Cl⁻ + 3K⁺ + 3OH⁻ = Fe(OH)₃↓ + 3K⁺ + 3Cl⁻

Fe³⁺ + 3OH⁻ = Fe(OH)₃↓

б)

2HCl + Na₂CO₃ = 2NaCl + CO₂↑ + H₂O

2H⁺ + 2Cl⁻ + 2Na⁺ + CO₃²⁻ = 2Na⁺ + 2Cl⁻ + CO₂↑+ H₂O

2H⁺ + CO₃²⁻ = CO₂↑+ H₂O

в)

Na₂SiO₃ + H₂SO₄ = Na₂SO₄ + H₂SiO₃

2Na⁺ + SIO₃²⁻ + 2H⁺ + SO₄²⁻ = 2Na⁺ + SO₄²⁻ + H₂SiO₃

SiO₃²⁻ + 2H⁺ = H₂SiO₃
