What is Matter?

Matter is anything that occupies space and has mass. It is a general term for the substance of which all physical objects consist.

What is Chemistry?

Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties

Five Branches of Chemistry organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry and biochemistry.

Organic Chemistry - the study of carbon and its compounds; the study of the chemistry of life. Inorganic Chemistry - the study of compounds not- covered by organic chemistry; the study of inorganic compounds or compounds which do not contain a C-H bond. Many inorganic compounds are those which contain metals. Analytical Chemistry - the study of the chemistry of matter and the development of tools used to measure properties of matter. Physical Chemistry - the branch of chemistry that applies physics to the study of chemistry. Commonly this includes the applications of thermodynamics and quantum mechanics to chemistry. Biochemistry - the study of chemical processes that occur inside of living organisms.

Pure vs. Applied Chemistry

Pure chemistry refers to pure research - just trying to figure out the properties of existing matter. Applied chemistry means you are using scientific knowledge of chemistry in order to solve a human problem.
