Chapter 1 - Foundations in Chemistry1. State the Law of Conservation of Matter, the Law of Conservation of Energy, and the Law of Conser-

vation of Matter and Energy. Be able to express these in words other than those used in the text. Give examples of each.

2. Describe and distinguish among the general properties of gases, liquids, and solids. 3. Define, distinguish among, and give examples of a chemical change, a physical change, a chemical

property, a physical property, an intensive property, and an extensive property. 4. Define, distinguish among, and give examples of substances, heterogeneous mixtures, homogene-

ous mixtures, elements, and compounds. 5. Know the names and symbols of the elements. 6. Know the fundamental SI units and the meanings of the prefixes. Know at least one conversion factor

relating metric and English units of mass, length, and volume. 7. Be familiar with conventions regarding exponential notation and significant figures. Apply them prop-

erly when doing mathematical operations. 8. Know how to construct unit factors from equalities. Use these in calculations that involve conversions

from one set of units to another (dimensional analysis). 9. Distinguish between mass and weight; accuracy and precision; density and specific gravity; and heat

and temperature. 10. Carry out calculations relating density, specific gravity, mass, and volume. 11. Identify significant figures and be able to use significant figures in multiplication, division, addition,

and subtraction. 12. Relate the Celsius, Fahrenheit, and Kelvin temperature scales. Convert a specified temperature on

one scale to the corresponding temperature on the other two scales. 13. Distinguish between endothermic and exothermic changes. Be able to carry out calculations that re-

late heat capacity or specific heat to the heat transfer that accompanies temperature changes. 14. Use your understanding of this chapter to recognize and solve a variety of types of questions.
