Chemistry is the study of the composition, structure, and properties of matter and the changes it undergoes.
Chemistry includes many different branches of study and research.  The following are six main branches of study.
  1. Organic chemistry - the study of most carbon-containing compounds.
  2. Inorganic chemistry - the study of all substances not classified as organic, mainly those compounds that do not contain carbon.
  3. Physical chemistry - the study of the properties, changes, and relationships between energy and matter.
  4. Analytical chemistry - the identification of the components and composition of materials.
  5. Biochemistry - the study of substances and processes occurring in living things.
  6. Theoretical chemistry - the use of mathematics and computers to design and predict thte properties of new compounds.

A chemical is any substance that has a definite composition.

Basic Research - Basic research is carried out for the sake of increasing knowledge, such as how and why a specific reaction occurs and what the properties of a substance are.

Applied Research - Applied research is generally carried out to solve a problem.

Technological Development - Technological development typically involves the production and use of products that improve our quality of life.
