  2. Chemical Equations • A chemical equation is a set of chemicals that are involved in a chemical reaction (chemical change). • For example • C6H12O6 + 6O2 6CO2 + 6H2O • The big numbers in front tell us how many of the whole molecule, these are called coefficients. • The little numbers to the right of an atom tell us how many there are of that atom in the whole molecule, these are called subscripts.

  3. Reactants • In the equation • C6H12O6 + 6O2 6CO2 + 6H2O • The C6H12O6 + 6O2 • C6H12O6 is a type of sugar called glucose AND • 6O2 is the oxygen in the air we breath. • Both the oxygen and the sugar are called the reactants. • You can always find the reactants on the left side of the arrow in a chemical equation.

  4. Products • In the equation • C6H12O6 + 6O2 6CO2 + 6H2O • The 6CO2 + 6H2O are the products. • The 6CO2 is 6 carbon dioxide molecules AND • The 6H2O is 6 water molecules. • These are called the products because when you put the reactants together you produce 6 water molecules and 6 carbon dioxide molecules. • Products are ALWAYS on the right in a chemical equation.
