Question

State the law of conservation of mass

Answer 1

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 + O 2 In this case mass of reactant =100g
