2Ca + O₂ = 2CaO
CaO + 3C = CaC₂ + CO (t)
CaC₂ + 2H₂O = Ca(OH)₂ + C₂H₂
Ca(OH)₂ + CO₂ = CaCO₃ + H₂O
CaO + H₂O = Ca(OH)₂
CaCO₃ + H₂O + CO₂ = Ca(HCO₃)₂
Ca(HCO₃) = CaCO₃ + CO₂ + H₂O (t)
CaCO₃ = CO₂ + H₂O (t)
CaO + CO₂ = CaCO₃
CaO + 2HCl = CaCL₂ + H₂O
Ca + 2HCL = CaCl₂ + H₂
Ca + H₂ = CaH₂
CaCl₂ + Ba = BaCl₂ + Ca
Ca + 2C = CaC₂ (t)
