Question

After the chemical reaction takes place, the mass of product is always:

  1. More than reactant
  2. Equal to reactant
  3. Less than reactant
  4. Depends on conditions

hintHint:

The mass of the reactant follows the law of conservation of mass.

The correct answer is: Equal to reactant


    The mass of reactants is always equal to the mass of reactants. This is called the law of conservation of mass. It was given by Antoine Lavoisier in 1789.
