PERFORMANCE OBJECTIVES / Chem. 11 - Dr. Daniel (Introduction to General, Organic, and Biochemistry by Bettelheim, Brown, and March, 8th Edition, 2007).

PERFORMANCE OBJECTIVES - Chapter 1

 At the end of this unit you should be able to:

  1. Define chemistry and matter and describe the two types of changes matter can undergo.  Classify any change as either a physical or a chemical change.
  2. When given a chemical equation or a word description, state if the reaction is a chemical or physical reaction.  
  3. Describe the difference between chemical properties and physical properties.  If given a property of a substance, determine if the property is a chemical or physical property.  
  4. Explain the relationship between a hypothesis, a theory, a law, and experimental facts and data in the use of the scientific method.
  5. Discuss the difference between physical changes and chemical changes, and classify any change as either a physical or a chemical change.
  6. Determine the number of significant figures in a numerical value, and indicate the uncertainty in the number.
  7. Be able to add, subtract, multiply, and divide numbers and express the answer with the correct significant figures and rounded correctly.
  8. Convert any number written in normal decimal notation to scientific notation, and vice versa.
  9. State the two parts of a measurement.
  10. Explain why we use the metric system.  State the metric units and abbreviations used to measure length, volume, mass, time, and temperature.
  11. Given the abbreviation of a metric prefix with a unit of measurement, state the name of measurement and the numeric value of the prefix.  Convert from one unit of measurement to a another measurement using the value of the prefixes.
  12. Be able to write the name of the following Greek prefixes used with SI and metric units, and write the abbreviation and numerical value of the prefix; kilo, deci, centi, milli, and micro.
  13. Perform conversions between units, including conversions within the metric system using the Greek prefixes, conversions within the English system, and conversions between the English and metric systems when given the conversion factor(s) or one of the above Greek metric prefixes.  Show how the unit cancel in converting from one measurement to another.
  14. Describe the Celsius (centigrade), Fahrenheit, and Kelvin temperature scales in terms of the freezing and boiling points of water, and perform conversions between the three temperature scales.
  15. Explain what is meant by state of matter, and indicate the three most common states of matter.  Describe the shape and volume of gases, liquids, and solids.
  16. Define density and specific gravity in your own words, and express it as an algebraic equation (formula).
  17. Use the density definition to solve for the density, mass, or volume when the other two quantities in the definition are known.
  18. Describe an experimental way to determine the density of a regularly shaped or an irregularly shaped object.
  19. Define energy, potential energy, and kinetic energy when given an example, describe how potential and kinetic energy are converted in to each other.  State the law of conservation of energy.
  20. Define heat energy and describe how it is related to temperature.
  21. Define specific heat.  When given the specific heat of two substances, describe which substance require more heat to change its temperature.
  22. Identify from a drawing or when shown the equipment, the following items: beaker, graduated cylinder, evaporating dish, Erlenmeyer flask, forceps, funnel, pipet, test tube, and watch glass.
