					CONSERVING CHEMICAL RESOURCES
Upon completion of this unit, you will be able to:
1. Compare and contrast science and technology. (Introduction)
2. State the law of conservation of matter, and apply the law by determining whether a given chemical
   equation is balanced. (A.2, A.3)
3. Describe the Spaceship Earth analogy, and apply it to the terms "throwaway" and "using up." (A.5, A.6,
   A.7)
4. List common types and sources of municipal waste, and describe attempts to reuse and recycle waste.
   (A.5, A.6, C.4, C.5)
5. Define and give examples of renewable and nonrenewable resources. (A.5, A7)
6. Distinguish between chemical and physical changes and/or properties when given specific examples of
   each. (B.1)
7. Classify selected elements as metals, nonmetals, or metalloids based on observations of their chemical and
   physical properties. (B.2, B.3)
8. Use the periodic table to (a) predict physical and chemical properties of an element; (b) write formulas for
   various compounds; (c) identify elements by their atomic masses and atomic numbers; and (d) locate
   periods and groups (families) of elements. (B.A, B.6)
9. Construct a workable periodic table and explain its organization, given chemical and physical properties of
   a set of elements. (B.5)
10. Compare the reactivities of selected elements, and explain the results in terms of the structure of their
   atoms. (B.7-B.9)
11. Discuss the development of new materials as substitutes for dwindling resources. (D.6)
12. Explain from a chemical viewpoint the problems and solutions involved in restoring the Statue of
   Liberty. (B.11)
13. List the three primary layers of our planet and some resources that are "mined" from each region. (C.1)
14. Write balanced chemical equations and relate them to the law of conservation of matter. (C.2)
15. Define the term mole, and calculate the molar mass of a compound when provided with its formula and
   the atomic masses of its elements. (C.3)
16. Outline the production of a metal from its ore (using copper as an example) and list four factors which
   determine the profitability of mining. (D.1)
17. Calculate the percent composition by mass of a specified element in a given compound. (D.2)
18. Define oxidation and reduction, and compare the three most common redox-reaction methods for
   separating metals from their ores. (D.4)
19. Use the concepts of the properties of materials to develop a currency for a new country. (E.1)
