Solved: Potassium superoxide, KO2, is often used in oxygen
Chapter , Problem 7.115(choose chapter or 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 KO21s2 react with each mole of CO21g2. (a) The products of the reaction are K2CO31s2 and O21g2. Write a balanced equation for the reaction between KO21s2 and CO21g2. (b) Indicate the oxidation number for each atom involved in the reaction in part (a). What elements are being oxidized and reduced? (c) What mass of KO21s2 is needed to consume 18.0 g CO21g2? What mass of O21g2 is produced during this reaction?
