Question

EXPLAIN in DETAIL about the law of conservation of mass.

Answer 1

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

Hey,
Ur answer is here,
The law of conservation of mass states that the mass of a closed system will remain constant in a chemical reaction. In other words, mass can neither be created nor destroyed in a chemical reaction. This law was first formulated by Antoine Laurent Lavoisier in 1789.

For example: When 100g of mercuric oxide is heated, 92.6 g of mercury and 7.4 g of oxygen are obtained as products.

i.e. HgO→ Hg + O2

In this case mass of reactant =100g

Mass of products = Mass of Hg + Mass of O2 = 92.6 + 7.4 = 100g

Thus, we obtain Mass of product = Mass of reactants

This verifies the law of conservation of mass.
