This video defines what a chemical reaction is and explains how chemical reactions obey the law of conservation of matter. Students will see real world examples of chemical reactions and come to understand that no matter is created or destroyed in a chemical reaction and that all the atoms in the reactants must be in the products. Viewers will also learn how chemical reactions are shown through the use of chemical formulas.
