| 1. Combustion of carbon in a stream of oxygen:
C + O2 = CO2.
2. Reaction of carbon dioxide with alkali:
CO2 + 2NaOH = Na2CO3 + H2O.
3. The reaction of decomposition of soda ash at t = 1000 ° C.
Na2CO3 = Na2O + CO2.
4. Precipitation of calcium carbonate when passing carbon dioxide through a solution of calcium hydroxide:
Ca (OH) 2 + CO2 = CaCO3 + H2O.
