Ca(OH)₂ = CaO + H₂O
CaO + 2HNO₃ = Ca(NO₃)₂ + H₂O
Ca(NO₃)₂ + K₂CO₃ = CaCO3 + 2KNO₃
CaCO₃ + H₂SO₄ = CaSO₄ + CO₂ + H₂O
CaSO₄ + 2NaOH = Ca(OH)₂ + Na₂SO₄
Ca(OH)₂ + 2HCl = CaCl₂ + 2H₂O
Ca(OH)₂ = CaO + H₂O
CaO + 2HNO₃ = Ca(NO₃)₂ + H₂O
Ca(NO₃)₂ + K₂CO₃ = CaCO3 + 2KNO₃
CaCO₃ + H₂SO₄ = CaSO₄ + CO₂ + H₂O
CaSO₄ + 2NaOH = Ca(OH)₂ + Na₂SO₄
Ca(OH)₂ + 2HCl = CaCl₂ + 2H₂O
