Now You Know

After completing this tutorial, you will be able to complete the following:

  • Apply the law of conservation of matter to changes in a system.
  • Explain that the total mass in a chemical reaction remains constant
  • Quantify the relationships between reactants and products in chemical reactions.

Everything You'll Have Covered

Chemical reactions occur when the atoms in the reactants rearrange themselves into new combinations to form products. During a chemical reaction, the state of matter may change between solids, liquids and gases. The total mass of the atoms involved in the reaction will not change. The sum of the reactants mass will be the same as the sum of the products mass.
