Pоtаssium chlоrаte decоmposes upon slight heаting in the presence of a catalyst, according to the reaction below. 2KClO3(s) → 2KCl(s) + 3O2(g) In a certain experiment, 40.0g KClO3 is heated until it completely decomposes. First, you need to calculate the theoretical yield of oxygen gas. The experiment is performed, the oxygen gas is collected, and its mass is found to be 14.9g. What is the percent yield for the reaction?
