Question

KO2 is use of
in closed-system
breathing apparatus.It removes
CO2 and H2O from exhaled air. The
water is removed by following reaction
KO₂ + H₂O - KOH + 02. The
use KOH remove CO2 as
follow KOH + CO2--KHCO3
What mass of H2O can be removed
by 235g of KO2​

Answer 1

Explanation:

Potassium superoxide, KO2, is utilised in closed system breathing apparatus. Exhaled air contains CO2 and H2O both of which are removed and the removal of water generates oxygen for breathing by the reaction: 4KO2(s)+2H2O(l)→3O2(g)+4KOH(s).
