They are central to the economic growth of the United States in the rubber, plastics, fuel.

The history of the chemical bond. When discussing the history of chemistry it’s always dangerous to point to the specific origin of an idea, since by its very definition, the scientific process relies upon the gradual refinement of ideas that came before. However, as is the case with a number of such ideas, one can point to certain seminal moments, and in the case of chemical bonding, a.

In fact, chemistry is known as the central science because it touches all other natural sciences, like biology, physics, geology, and more. Chemistry is a physical science, and it is the study of the properties of and interactions between matter and energy. In other words, chemistry is a.
