Question

5. In a reaction 4.6g of barium chloride reacts with 3.4g of sodium sulphate. The products were
2.8g of sodium chloride and 5.2 g of barium sulphate. The reaction takes place as follows.
Barium chloride + Sodium sulphate → Barium sulphate + Sodium chloride.
Show that the above observation is in agreement with the law of conservation of mass. State the
law.

Answer 1

Answer: 4.6+3.4=2.8+5.3 (Barium chloride + Sodium sulphate → Barium sulphate + Sodium chloride)

Explanation: Law of conservation of mass

in a chemical reaction the mass of reactants and products remains conserved
