Law of Conservation of Mass

The Law of Conservation of Mass states that matter can be changed from one form to another, mixtures can be separated or made, and pure substances can be decomposed, but the total amount of mass has to remain the same.

Reactant and Product

  • Reactant: A substance that takes part in and undergoes change during a reaction.

  • Product: The substances that result from this recombination of atoms


Oxygen combines with a hydrocarbon to form carbon dioxide and water.
  • CXHY + O2 ---> CO2 + H2O


Two or more compounds combine to form one compound.

  • A + B ---> AB


One or compound produces two or more products.

  • AB ---> A + B


An element and a compound form a new element and a compound.

  • A + BC ---> A + B


Two compounds form two new compounds.

  • AC + BD ---> AD + BC

Acid/Base Reaction

An acid and Base react to form water and salt.

  • acid + base ---> water + salt
