Answer:
The law of conservation of mass states that during in a physical or chemical change, the mass of products remains equal to the total of reactants.
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.
