What happens when Solid potassium oxide is added to a container of carbon dioxide gas?

When solid potassium oxide (K2O) is added to a container of carbon dioxide (CO2) gas, a chemical reaction occurs. Potassium oxide reacts with carbon dioxide to form potassium carbonate (K2CO3). This reaction is a double displacement reaction, where the potassium from potassium oxide replaces the carbon in carbon dioxide, resulting in the formation of potassium carbonate. The balanced chemical equation for this reaction is: K2O + CO2 → K2CO3.
