Vedclass · Answer

(D) Potassium superoxide $(KO_2)$ is widely used in submarines and space shuttles for oxygen generation because it reacts with $CO_2$ to produce $O_2$ and removes $CO_2$ simultaneously.The reaction is: $4KO_2 + 2CO_2 \rightarrow 2K_2CO_3 + 3O_2$.Sodium peroxide $(Na_2O_2)$ is also used for the same purpose as it reacts with $CO_2$ to release $O_2$: $2Na_2O_2 + 2CO_2 \rightarrow 2Na_2CO_3 + O_2$.Potassium ozonide $(KO_3)$ also releases oxygen upon reaction with $CO_2$ and moisture,making it useful for similar applications.
