Question

What is the law of conservation of mass? Explain it with example.

Answer 1

Answer:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

Answer 2

According to law of conservation of mass,

mass can neither be created nor be destroyed

Example:

2H2 + O2 --> 2H2O

4gm + 32gm = 2(18)gm

36gm = 36gm
