Question

1. Explain the process and precautions in verifying law of conservation of mass.​

Answer 1

Answer:Precaution: To initiate the chemical reaction tilt the flask efficiently so that barium chloride solution gets mixed with the sodium sulphate solution in the flask. The mass of both of the solution before reaction was found to be same after the product is formed. So, this verifies the law of conservation of mass.

Answer 2

Law of conservation of mass states that “Matter is neither created nor destroys in a chemical reaction. More simply, the mass of products is equal to the mass of reactants in a chemical reaction.
