  1. General Chemistry Chapters 11, 3, 10, 12, 13, 14, 16 and 19

  2. CHEMICAL REACTIONS INTRODUCING: EQUATIONS, BALANCING EQUATONS, FIVE TYPES OF REACTIONS,

  3. DESCRIBING CHEMICAL REACTIONS 11.1.1 DESCRIBE how to write a word equation. 11.1.2 DESCRIBE how to write a skeleton equation. 11.1.3 DESCRIBE the steps for writing a balanced chemical equation

  4. WRITING CHEMICAL EQUATIONS A chemical equation is composed of three parts: REACTANTS YIELD SIGN PRODUCTS Iron (III) oxide Iron + Oxygen

  5. WRITING CHEMICAL EQUATIONS A yield sign ALWAYS “points” at the REACTANTS YIELD SIGN PRODUCTS Iron (III) oxide Iron + Oxygen

  6. CHEMICAL QUANTITIES INTRODUCING: MOLE, PRESSURE AVOGADRO’S NUMBER, MOLAR MASS & VOLUME, PERCENT COMPOSITION

  7. MEASURING MATTER Substances may be measured by one of three different methods: By count By mass By volume

  8. MEASURING MATTER By count includes a value and key term related to the matter being measured. Examples include: 1 dozen apples = 12 apples 3 for $2.40

  9. MEASURING MATTER By mass includes a value, an unit, and key term related to the matter being measured. Difference between mass and weight. Mass is the same throughout the universe. Weight depends on gravity.

  10. MEASURING MATTER By mass includes a value, an unit, and key term related to the matter being measured. Examples include: 1 dozen apples = 2.0 kg of apples 1 dozen apples = 3.0 lbs of apples

  11. MEASURING MATTER By volume includes a value, an unit, and key term related to the matter being measured. Volume is the amount of space and an object occupies. Examples include: 1 dozen apples = 0.20 bushel of apples

  12. MEASURING MATTER If 0.20 bushel is 1 dozen apples and 12 apples has a mass of 2.0 kg, what is the mass of 0.50 bushel of apples? C.F. : 0.20 bushel = 12 apples 12 apples = 2.0 kg. Given times conversion factor(s) = Resulting unit 0.5 bushel 12 apples/0.20 bushel C.F. Given 2.O kg./12 apples

  13. MEASURING MATTER Assume 2.0 kg of apples is 1 dozen & that each apple has 8 seeds. How many apple seeds are in 14 kg of apples? C.F. : 2.0 kg = 12 apples 1 apple = 8 seeds Given times conversion factor(s) = Resulting unit 14 kg 1 apple/8 seeds C.F. Given 12 apples/2.0 kg

  14. MEASURING MATTER How many bushels of apples are in 1.0 kg of apples? C.F. : 2.0 kg = 12 apples 0.20 bushel = 12 apples Given times conversion factor(s) = Resulting unit 0.20 bushel/12 apples 1.0 kg 12 apples/2.0 kg C.F. Given
