1) CaO + CO₂ = CaCO₃
2) CaCO₃ + H₂O + CO₂ = Ca(HCO₃)₂
CaCO₃ + H₂O + CO₂ = Ca²⁺ + 2HCO₃⁻
3) Ca(HCO₃)₂ = CaCO₃ + H₂O + CO₂
4) CaCO₃ + HCl = H₂O + CO₂ + CaCl₂
CaCO₃ + 2H⁺ + 2Cl⁻ = H₂O + CO₂ + Ca²⁺ + 2Cl⁻
CaCO₃ + 2H⁺ + 2Cl⁻ = H₂O + CO₂ + Ca²⁺
5) CaCl₂ + 2AgNO₃ = 2AgCl + Ca(NO₃)₂
Ca²⁺ + 2Cl⁻ + 2Ag⁺ + 2NO₃⁻ = 2AgCl + Ca²⁺ + 2NO₃⁻
Cl⁻ + Ag⁺ = AgCl
