Question

Law of conservation of mass is also applicable in chemical equation.explain 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.

Explanation:

example.

Combustion process: Burning of wood is a conservation of mass as the burning of wood involves Oxygen, Carbon dioxide, water vapor and ashes.

Chemical reactions: To get one molecule of H2O (water) with the molecular weight of 10, Hydrogen with molecular weight 2 is added with Oxygen whose molecular weight is 8, thereby conserving the mass.

Answer 2

Answer:

Law of conservation of mass-mass can't be created nor be destroyed.

so when we balanced the equation we got LHS=RHS

e.g.2Mg+O2gives 2MgO
