A. Role of Chemistry in Society
Applications of chemical science have contributed significantly to the advancement of human civilization (1, 2, 3). With a growing understanding and ability to manipulate chemical molecules, the post-World War II chemist was considered a societal problem solver. They synthesized crop-enhancing agricultural chemicals to ensure a constant and viable food supply. They played a significant role in the eradication of deadly diseases by developing life-saving pharmaceuticals and chemical pesticides. Chemists also developed innovative plastics and synthetic fibers for use in a both industrial and consumer products (1, 2, 3). The chemical industry has been a vital sector of the modern industrialized economy (2, 3). The chemical and allied manufacturing sectors in the United States employ over two million individuals. This accounts for approximately 11% of our nations manufacturing and industrial workers (4). The chemical manufacturing sector of the U.S. Role Of Chemistry In Human Welfare

Chemistry is the science of matter and the changes it undergoes. The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned with the composition, behavior (or reaction), structure, and properties of matter, as well as the changes it undergoes during chemical reactions. It is a physical science which studies various substances, atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, and which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes. Disciplines within chemistry are traditionally grouped by the type of matter being studied or the kind of study. These include inorganic chemistry, the study ofinorganic matter; organic chemistry, the study of organic (carbon based) matter; biochemistry, the study of substances found in biological organisms;physical...
