Question

Define Law of conservation of mass.​

Answer 1

Answer:

➡The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy.

➡The mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Answer 2

Required Answer :-

$\bf \large\underline{Law \:of \:Conservation\: of\: mass\: :-}$

Proposed by the French chemist Antoine Lavoisier (1774) .

Mass can neither be created nor destroyed in a chemical reaction.

⠀⠀⠀⠀⠀⠀⠀⠀⠀Or

For any chemical process in a closed system, the mass of the reactants must be equal to the mass of the products.

Example:

⠀⠀⠀⠀ C + O2 = CO2

⠀⠀⠀⠀ 12g + 32g = 44g

“To satisfy the Law of conservation of mass the chemical equation should be balanced.”
