1) CaCl2 + Na2CO3 = CaCO3 + 2 NaCl (calcium carbonate).
2) CaCO3 + H2CO3 = Ca (HCO3) 2 (calcium bicarbonate).
3) Ca (HCO3) 2 = CaCO3 + CO2 + H2O (conditions: temperature; calcium carbonate, carbon dioxide (carbon monoxide (4)).
4) CaCO3 + H2SiO3 = CaSiO3 + CO2 + H2O (calcium silicate, carbon dioxide (carbon monoxide (4)).
