Vedclass · Answer

(A) Sodium peroxide $(Na_2O_2)$ reacts with carbon dioxide $(CO_2)$ to produce sodium carbonate $(Na_2CO_3)$ and oxygen gas $(O_2)$.The chemical reaction is: $2Na_2O_2(s) + 2CO_2(g) \rightarrow 2Na_2CO_3(s) + O_2(g)$.This property makes it useful for regenerating oxygen and removing carbon dioxide in confined spaces like submarines.
