equations for the reaction between potassium superoxide and water giving potassium hydroxide, hydrogen peroxide, and oxygen and reaction between potassium superoxide also reacts with carbon dioxide to form potassium carbonate and oxygen has to be given. Effectiveness of potassium superoxide in breathing equipment has to be commented. Concept Introduction: A balanced equation should be obeying the law of conservation of mass. Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a chemical reaction atoms are neither be created nor be destroyed”.
