1.	4.9 g of KClO_(3) when heated produced 1.92 g of oxygen and the residue of KCl left was found to weigh 2.96 g. Show that the data illustrates the law of conservation of mass.
Answer» Solution :`2KClO_(3)rarr2KCl+3O_(2)` MASS of reactants =4.9 G , Mass of products`= (1.92 + 2.96) = 4.88 g` As the mass of the products is nearly same as that of the reactants, this illustrates the Law of conservation of mass.
