Detailed explanation-1: -Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change-none is created or destroyed. This concept is called the Law of Conservation of Mass.
Detailed explanation-2: -According to the ‘Law of conservation of mass’, mass is neither created nor destroyed in a chemical reaction.
Detailed explanation-3: -A given compound always contains exactly the same proportion of elements by weight can be explained by the Law of Constant Proportion. Hence this is an incorrect statement about the Law of Conservation of Mass.
Detailed explanation-4: -The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
