What is Chemistry?
the study of matter
and its changes
Areas of Chemistry
• Organic
• Inorganic
• Analytical
• Physical
• Biochemistry
The study of most carbon-containing compounds
The study of all substances not classified as organic, mainly those compounds that do not contain carbon
The identification of the components and composition of materials
The study of the properties, changes, and relationshipsbetween energy and matter
The study of substances and processes occurring inliving things
Areas of Chemistryorganic physical

everything except
carbon
e.g., compounds
containing metals
the study of carbon-
