Explain what matter is. (Section 1.1; Exercise 1.2) 2. Explain the difference between the terms physical and chemical as they apply to the properties of matter and changes in matter. (Section 1.2; Exercises 1.8 and 1.10) 3. Classify matter as an element, compound, homogenous mixture, or heterogeneous mixture. (Section 1.3; Exercises 1.16, 1.20, and 1.22) 4. Describe four measurement units used in everyday activities. (Section 1.4; Exercise 1.26)) 5. Convert measurements within the metric system into related units. (Section 1.5; Exercises 1.28 and 1.38)) 6. Convert temperatures measured in Fahrenheit to Celsius and vice versa. (Section 1.5; Exercises 1.41 and 1.42) 7. Express numbers using scientific notation. (Section 1.6; Exercises 1.46 and 1.47) 8. Perform calculations with numbers expressed in scientific notation. (Section 1.6; Exercises 1.58 and 1.59) 9. Express measurements and calculations using the correct number of significant figures. (Section 1.7; Exercises 1.62 and 1.64) 10. Use dimensional analysis to solve numerical problems.
