Answer 1

KO₂ (potassium super oxide) is used in oxygen cylinders in space and submarines because it absorbs CO₂ and increases O₂ content.

Explanation:

\[\ce{2KO2 + 2H2O -> 2KOH + H2O2 + O2}\]

As an oxidising agent, KO₂ is utilised. Because it creates oxygen and eliminates carbon dioxide, it is employed as an air purifier in space capsules, submarines, and breathing masks.
