  1. Year 10 C Pathway Mr. D. Patterson Introductory chemistry

  2. Outcomes • Use the coefficients in a balanced chemical equation to write the mole relationship for the molar amounts of any two substances appearing in a balanced chemical equation.

  3. Baking a cake • My Gran’s wonderful chocolate cake requires 2 eggs, 1 milk and 2 flour to make 1 cake. • As a chemical reaction? 2 Egg + Milk + 2 Flour -> Cake

  4. Baking a cake 2 Egg + Milk + 2 Flour -> Cake • How many eggs do I need for 3 cakes? • How many cakes could I make from 3 milk if I had enough of the other ingredients? • How did you answer these questions?

  5. Stoichiometry 2 Egg + Milk + 2 Flour -> Cake • How many eggs do I need for 3 cakes?

  6. Stoichiometry • To find the number of moles of an unknown product or reactant from a chemical equation:

  7. Example Problem • How many moles of HCl are required to produce 4.5 moles of hydrogen gas?

  8. Example Problem • How many moles of MgCl are produced when 8 moles of Mg are used?

  9. Outcomes • Use the coefficients in a balanced chemical equation to write the mole relationship for the molar amounts of any two substances appearing in a balanced chemical equation. • Checkpoint 10.3 • Set 21
