Question

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). 
Express your answer as a chemical equation. Identify all of the phases in your answer. 
Indicate the oxidation number for each atom involved in the reaction in part A. Before the reaction: Enter your answers numerically separated by commas.
