  • Inorganic chemistry: the study of non-carbon-based compounds

  • Physical chemistry: the study of the properties and behavior of matter

  • Analytical chemistry: the study of the composition and structure of matter

  • Biochemistry: the study of chemical processes in living organisms



States of Matter
