Chemistry 108 - Review Sheet for Exam #1

As a guide for studying, you should be familiar with the concepts listed below.

Chapter 2: Measurements and Calculations
  • matter & states of matter (solids, liquids & gases)
  • physical & chemical properties (what is the difference? give examples)
  • physical & chemical changes (what is the difference? give examples)
  • element, molecule, compound & mixtures (how do these differ?)
  • pure substance & solutions (definitions & examples)
  • homogeneous & heterogenous mixtures (give example)
  • distillation & filtration (differences & definitions)
  • energy - calorie, joule & specific heat capacity (values & definitions)
  • measurements, units, SI units (what are these units?)
