2. Learners will know… The Law of Conservation of Mass as it relates to chemical changes of substances The parts of a chemical reaction Learners will be able to… Write and balance chemical equations Perform stoichiometry calculations

3. Chemical properties Chemical changes Chemical formulas Chemical bonding The MOLE Mole conversions CHEMICAL EQUATIONS Balancing chemical equations Stoichiometry Types of chemical reactions

5. There is no direct way to determine amount (mass) of product from amount (mass) of reactant (or vice versa!!) Once again, the MOLE is our GATEWAY!

6. A method for predicting AMOUNT of Product made in a chemical reaction Reactant used in a chemical reaction MASS (g) PRODUCT MASS (g) REACTANT MOLES REACTANT MOLES PRODUCT MOLE RATIO

7. Mole ratios are

8. Solving FOR on TOP Converting FROM on BOTTOM CONVERSION FACTORS: 2 moles NO 2 1 mole N 2 1 mole N 2 2 moles NO 2

9. What is the mole ratio for magnesium to magnesium oxide? What is the conversion factor to convert to moles of magnesium oxide from moles of magnesium?

10. What is the mole ratio for oxygen (gas) to magnesium oxide? What is the conversion factor to convert to moles of oxygen from moles of magnesium oxide?

11. WORKSHEET: Mole Ratios

12. A method for converting between amounts of products and reactants Used to predict amount of product Used to determine amount of reactant

13. How many grams of oxygen are used to make 10g of magnesium oxide? NEED TO KNOW: Molar mass oxygen Molar mass magnesium oxide Mole ratio oxygen and magnesium oxide Follow MOLE TUNNEL!

14. Hany grams of oxygen are used to make 10g of magnesium oxide?
