This sulphur again was not ordinary sulphur, but some principle derived from it, which constituted the philosopher's stone or elixir - white for silver and yellow or 1 " Some traditionary knowledge might be secreted in the temples and monasteries of Egypt; much useful experience might have been acquired in the practice of arts and manufactures, but the science of chemistry owes its origin and improvement to the industry of the Saracens. RUTHENIUM [[[symbol]] Ru, atomic weight To' 7 (O = 0)1, in chemistry, a metallic element, found associated with platinum, in platinum ore and in osmiridium. Like most great teachers he published a text-book, and his Traite de Chimie elementaire, theorique et pratique (4 vols., Paris, 1813-16), which served as a standard for a quarter of a century, perhaps did even more for the advance of chemistry than his numerous original discoveries. Experiment definition is - test, trial. - (Dr Bridges.) His attention was specially turned to chemistry by J. Bucquet (1746-1780), the professor of chemistry at the Medical School of Paris, and in 1784 he was chosen to succeed P. J. Macquer (1718-1784) as lecturer in chemistry at the college of the Jardin du Roi, where his lectures attained great popularity. Only first 15 results shown. Four years afterwards he graduated, and immediately became a private lecturer on chemistry in the French capital. It is hardly necessary to say that science has made enormous advance in the chemistry of the universe since these words were written. One of the earliest, if not the earliest, was the investigation, published in 1830, which proved the polymerism of cyanic and cyanuric acid, but the most famous were those on the oil of bitter almonds (benzaldehyde) and the radicle benzoyl (1832), and on uric acid (1837), which are of fundamental importance in the history of organic chemistry. (physical, environmental, organic, theoretical, applied) " He is interested in brain chemistry. Most of his work, however, lay in the domain of inorganic chemistry. green chemistry - branch of chemistry concerned with lessening the environmental effect of chemicals, including development of new materials and processes. Thorpe, Essays in Historical Chemistry (2nd ed., 1902). the; it; i; and; a; which; now; make; mind; had; been; god; astronomy; chemistry; suchlike; alway; eglington; let; amighty; favour; through; done Man's place is not even central, as he appears a temporary inhabitant of a minor planet in one of the lesser stellar systems. Fourcroy at the Ecole Polytechnique, where subsequently (1809) he became professor of chemistry, and from 1808 to 1832 he was professor of physics at the Sorbonne, a post which he only resigned for the chair of chemistry at the Jardin des Plantes. This institution was taken over by the Government in 1853, becoming the Royal College of Chemistry, and incorporated with the Royal School of Mines; in 1881 the names were changed to the Normal School of Science and Royal School of Mines, and again in 1890 to the Royal College of Science. Four years later he was appointed also to the chair of chemistry. It is a powerful reducing agent, and is frequently employed for this purpose in organic chemistry; thus hydroxy acids are readily reduced on heating with the concentrated acid, and nitro compounds are reduced to amino compounds, &c. It is preferable to use the acid in the presence of amorphous phosphorus, for the iodine liberated during the reduction is then utilized in forming more hydriodic acid, and consequently the original amount of acid goes much further. He also studied the chemistry of combustion and of respiration, and made experiments in physiology, where, however, he was hampered by the "tenderness of his nature" which kept him from anatomical dissections, especially of living animals, though he knew them to be "most instructing.". I think it's something about my body chemistry that they don't like. Especially prominent is the fact that polymerism and metamerism are mainly reserved to the domain of organic chemistry, or the chemistry of carbon, both being discovered there; and, more especially, the phenomenon of metamerism in organic chemistry has largely developed our notions concerning the structure of matter. In chemistry the term salt is given to a compound formed by substituting the hydrogen of an acid by a metal or a radical acting as a metal, or, what comes to the same thing, by eliminating the elements of water between an acid and a base. chemistry definition: 1. the scientific study of the basic characteristics of substances and the ways in which they react….
