CaCO3–CaCl2–Ca–CaO–Ca(OH)2–CaCO3–Ca(HCO3)2–CaCO3

Question

CaCO3–CaCl2–Ca–CaO–Ca(OH)2–CaCO3–Ca(HCO3)2–CaCO3

Answer 1

1. CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O
2. CaCl₂ + 2Li = 2LiCl + Ca
3. 2Ca + O₂ = 2CaO
4. CaO + H₂O = Ca(OH)₂
5. Ca(OH)₂ + H₂CO₃ = CaCO₃ + 2H₂O
6. CaCO₃ + H₂CO₃ = Ca(HCO₃)₂
7. Ca(HCO₃)₂ + 2LiOH = CaCO₃↓ + Li₂CO₃ + 2H₂O
