  • Chemistry 12.1
  • The Arithmetic of Equations
    • More than 3000 cocoons are needed to produce enough silk to make just one elegant Japanese kimono. Like silk manufacturers, chemists must know how much reactant they need to make a certain amount of product. Determining the quantities of reactants and products in a reaction requires a balanced chemical equation.

    • Using Everyday Equations
      • How is a balanced equation like a recipe?
    12.1
  • Using Everyday Equations
        • A balanced chemical equation provides the same kind of quantitative information that a recipe does.

  • Using Balanced Chemical Equations
    • Using Balanced Chemical Equations
      • How do chemists use balanced chemical equations?
    12.1
  • Using Balanced Chemical Equations
        • Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction.
        • The calculation of quantities in chemical reactions is a subject of chemistry called stoichiometry .
