Question

Q1. WITH THE HELP OF EXAMPLE EXPLAIN THE LAW OF
Conservation OF Masand LAW OF CONSTANT
COMPOSITION.​

Answer 1

Answer:

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.

Answer 2

Explanation:

Law of Conservation of Mass

This law state that "Mass neither be created nor be destroyed but is converted from one form to another form" in a balanced chemical reaction

For eg. CaCO3 (s) ---------> CaO (s) + CO2 (g)

100g 56g + 44g

Law of Constant Composition

This law states that "a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation".

For eg. Water obtained from any source like river, lake, sea, well, etc contains H20 in H:O 1:8
