Chemistry is the science which investigates the composition and properties of bodies and by which we are enabled to explain the causes of the natural changes which takes place in material substances. As a science, chemistry is of the highest importance of mankind, since by its investigations the practical arts are constantly improving. All chemical knowledge is founded on analysis and synthesis that is the decomposition of bodies or the separation of compounds into their simple elements or the re-composition of simple bodies into compounds. ![]() |
