Carbon → carbon dioxide → sodium carbonate → calcium carbonate → carbon dioxide

C → CO2 → Na2CO3 → CaCO3 → CO2

1) O2 + C → CO2 ↑ (compound reaction);

2) Na2O + CO2 ↑ → Na2CO3 (compound reaction);

3) Na2CO3 + Ca (OH) 2 ↓ → CaCO3 ↓ + 2NaOH (exchange reaction);

4) CaCO3 ↓ → CaO + CO2 ↑ (decomposition reaction).
