• Usual sequence: General chemistry  Organic chemistry  Physical chemistry or Analytical chemistry  Biochemistry or inorganic chemistry or organometallic chemistry

• Substances come in three forms
• Substances can be pure or mixtures
• Pure substances can be elements or compounds
• Measurements use the SI units; conversion factors allow unit conversions
• Scientific notation allows easy comparison of numbers
