Write the reaction equation: C = CO = CO2 = Na2CO3 = NaHCO3

1) 2C + O2 = 2CO (when carbon interacts with oxygen, carbon monoxide is formed);

2) 2CO + O2 = 2CO2 (when carbon monoxide interacts with oxygen, carbon dioxide is formed);

3) CO2 + 2NaOH = Na2CO3 + H2O (when carbon dioxide interacts with sodium hydroxide, sodium carbonate and water are formed);

4) Na2CO3 + CO2 + H2O = 2NaHCO3 (sodium bicarbonate is formed when sodium carbonate interacts with carbon dioxide and water).
