Law of Conservation of Mass or Matter
Law of Conservation of Mass or Matter
Law of Conservation of Mass: It states, “mass can neither be created nor be destroyed during a chemical reaction.” This means that in any chemical reaction, the total mass of the reactants is equal to the total mass of the products and there is no change in mass during the chemical reaction. It is also known as law of indestructibility of matter.
Illustration: If 4.0 g of sodium carbonate reacts with 10 g of hydrochloric acid, it results in the formation of 2.5 g of carbon dioxide and 11.5 g of sodium chloride solution. Show that these results are in accordance with the law of conservation of mass.
Here, total mass of reactants = 4.0 + 10 = 14 g
