After determining the composition of a mixture of KClO3 and KCl, it is found that the calculated amount of KCl is incorrectly high. The most likely cause of the this is that A) KCl also decomposed during the reaction. B) some of the sample powder was spilled after weighing. C) a small amount of KClO3 did not decompose, resulting in a smaller mass loss than should have occurred. D) KClO3 also released Cl2 gas during the reaction.
