Question 11
5.3 g of sodium carbonate and 6.0 g of acetic acid react to produce 2.2 g of carbon dioxide, 0.9 g of water, and 8.2 g of sodium acetate. Verify whether the law of conservation of mass is valid.
View Answer Hide Answer
  • Reactants = 5.3 + 6.0 = 11.3 g .
  • Products = 2.2 + 0.9 + 8.2 = 11.3 g .
  • Reactants = products → the law is valid .
Verify Conservation of Mass Reactants equal 11.3 g Products equal 11.3 g So the law is valid
