Chapter 7, Problem 7.111(choose chapter or problem)
Potassium superoxide, KOz, is often used in oxygen masks (such as those used by firefighters) because K02 reacts with C02 to release molecular oxygen. Experiments indicate that 2 mol of K02(s) react with each mole of C02{g). (a) The products of the reaction are K2C03(s) and 02{g). Write a balanced equation for the reaction between K02(s) and COz(g). (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 K02(s) is needed to consume 18.0 g C02(g)? What mass of 02{g) is produced during this reaction?
