KO_(2) ( potassium super oxide ) is used in space and submarines because it :

Potassium superoxide KO_(2) , is utillised in closed system breathing apparatus. Exhaled air contains CO_(2) and H_(2)O , both of which are removed and the removal of water generates oxygen for breathing by the reaction 4KO_(2(s))+2H_(2)O_((l))rarr 3O_(2(g))+ 4KOH_((s)) The potassium hydroxide removes CO_(2) from the apparatus by the reaction: KOH_((s))+CO_(2(g))rarr KHCO_(3(s)) (a) What mass of KO_(2) generates 20 gm of oxygen? (b) What mass of CO_(2) can br removed from the apparatus by CO_(2) can be removed from the apparatus by 100gm of KO_(2) ?
