Summary – Law of Conservation of Mass
The Law of Conservation of Mass is a fundamental concept in chemistry and physics, articulating that mass cannot be created or destroyed in an isolated system during chemical or physical transformations. Essentially, it means that the total mass before and after a reaction remains unchanged. This principle was pivotal in advancing chemistry, revealing that substances transform rather than vanish.
The law applies to both physical changes, like ice melting into water without mass alteration, and chemical changes, such as the reaction between sodium hydroxide and hydrochloric acid to produce sodium chloride and water, where the mass of the products equals the mass of the reactants. It’s symbolized in equations as the mass of reactants equaling the mass of products.
However, it’s noted that during nuclear reactions, this law does not hold because mass can be converted into energy, demonstrating a limitation of the law in certain scenarios.
Law of Conservation of Mass
Law of Conservation of Mass: The law of conservation of mass states that the mass can neither be created nor destroyed in a chemical reaction. This implies, in a closed system the mass of the elements involved initially in a chemical reaction is equal to the mass of the product obtained by the reaction.
Hence, for any type of chemical reaction, the total mass of the reactants and the products involved is conserved. This concept of mass conservation is widely used in chemistry and other fields like mechanics, dynamics, etc.
