Measuring the weights of Products and Reactants

Explanation:

  • The amount of matter is conserved before and after the completion of the reaction.
  • When matter changes from one form to another it is not destroyed that is the amount remains the same.
  • We can check this by going through a reaction and measuring their masses before and after the completion of the reaction.
  • If the weight is equal, it proves the conservation of mass.
