Answer 1

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

Explanation:

\[\ce{4KO2 + 2CO2 -> 2K2CO3 + 3O2}\]

As an oxidising agent, KO₂ is used. It is used in space capsules as an air purifier. It is used in submarines and breathing masks because it produces oxygen and removes carbon dioxide.
