Problem: Potassium superoxide, KO2, is often used in oxygen masks (such as those used by firefighters) because KO2 reacts with CO2 to release molecular oxygen. Experiments indicate that 2 mol of KO2 (s) react with each mole of CO2(g).The products of the reaction are K2CO3(s) and O2(g). Write a balanced equation for the reaction between KO2 (s) and CO2 (g).

FREE Expert Solution

We have to write a balanced equation for the reaction of potassium superoxide (KO2) with carbon dioxide (CO2).


The reaction between KO2 and CO2 produces K2CO3 and O2.

KO2(s) + CO2(g) → K2CO3(s) + O2(g)
