The chemical reaction of calcium reacting with carbon dioxide can be represented in steps as follows:
2Ca + O2 → 2CaO
CaO + CO2 → CaCO3
CaCO3 + H2CO3 → Ca(HCO3)2
Ca(HCO3)2 → CaCO3 + CO2
Overall reaction:
2Ca + O2 + 2CO2 + 2H2O → 2CaCO3 + 2CO2
This demonstrates the pathway of calcium reacting with carbon dioxide to form calcium carbonate and carbon dioxide gas.
The chemical reaction of calcium reacting with carbon dioxide can be represented in steps as follows:
Calcium (Ca) reacts with oxygen (O) to form calcium oxide (CaO):2Ca + O2 → 2CaO
Calcium oxide (CaO) reacts with carbon dioxide (CO2) to form calcium carbonate (CaCO3):CaO + CO2 → CaCO3
Calcium carbonate (CaCO3) reacts with carbonic acid (H2CO3) to form calcium bicarbonate (Ca(HCO3)2):CaCO3 + H2CO3 → Ca(HCO3)2
Calcium bicarbonate (Ca(HCO3)2) decomposes into calcium carbonate (CaCO3) and carbon dioxide (CO2):Ca(HCO3)2 → CaCO3 + CO2
Overall reaction:
2Ca + O2 + 2CO2 + 2H2O → 2CaCO3 + 2CO2
This demonstrates the pathway of calcium reacting with carbon dioxide to form calcium carbonate and carbon dioxide gas.
