This is a series of chemical reactions involving carbon dioxide (CO2) and calcium carbonate (CaCO3) that result in the formation of calcium bicarbonate (Ca(HCO3)2):

CO2 combines with water (H2O) to form carbonic acid (H2CO3):
CO2 + H2O -> H2CO3

Carbonic acid (H2CO3) then reacts with calcium carbonate (CaCO3) to form calcium bicarbonate (Ca(HCO3)2) and calcium oxide (CaO):
H2CO3 + CaCO3 -> Ca(HCO3)2 + CaO

Therefore, the overall reaction is:
CO2 + CaCO3 -> Ca(HCO3)2
