• Sceptical Chymist
  • Chemistry as a body of knowledge distinct from alchemy began to emerge when a clear differentiation was made between them by Robert Boyle in his work The Sceptical Chymist (1661). (wikipedia.org)
  • The Sceptical Chymist - Robert Boyle 1661 Description: Boyle, in the form of a dialogue, argued that chemical theories should be firmly grounded in experiment before their acceptance, and for the foundation of chemistry as a science separate from medicine and alchemy. (wikipedia.org)
  • Questions
  • It is often seen as linked to the quest to turn lead or another common starting material into gold, though in ancient times the study encompassed many of the questions of modern chemistry being defined as the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies by the early 4th century Greek-Egyptian alchemist Zosimos. (wikipedia.org)
  • process
  • It is an oxidation followed by a reduction process. (rsc.org)
  • One small but illustrative use is its use in the walls of self-cleaning ovens as a hydrocarbon oxidation catalyst during the high-temperature cleaning process. (wikipedia.org)
  • Process chemistry is distinguished from medicinal chemistry, which is the arm of pharmaceutical chemistry tasked with designing and synthesizing molecules on small scale in the early drug discovery phase. (wikipedia.org)
  • Oftentimes, in searching for the shortest, most efficient synthetic route, process chemists must devise creative synthetic solutions that eliminate costly functional group manipulations and oxidation/reduction steps. (wikipedia.org)
  • Cost efficiency is of paramount importance in process chemistry and, consequently, is a focus in the consideration of pilot plant synthetic routes. (wikipedia.org)
  • Most large pharmaceutical process chemistry and manufacturing divisions have devised weighted quantitative schemes to measure the overall attractiveness of a given synthetic route over another. (wikipedia.org)
  • Auto-oxidation is a process responsible for deterioration of paints and food and lab hazards such as diethyl ether peroxide. (wikipedia.org)
  • modern chemistry
  • It was unsuccessful in explaining the nature of matter and its transformations, but, by performing experiments and recording the results, alchemists set the stage for modern chemistry. (wikipedia.org)
  • The book was one of the first to describe a modern atomic theory, a theory that lies at the basis of modern chemistry. (wikipedia.org)
  • Science
  • This blog will cover and explain the specification for Edexcel triple science course 2013 Chemistry. (blogspot.co.uk)
  • Consequently, the emphasis in soil chemistry has shifted from pedology and agricultural soil science to an emphasis on environmental soil science. (wikipedia.org)
  • Chemistry is considered to have become an established science with the work of Antoine Lavoisier, who developed a law of conservation of mass that demanded careful measurement and quantitative observations of chemical phenomena. (wikipedia.org)
  • state
  • The reactants are free state elements, so their oxidation numbers are each zero. (chemistry-reference.com)
  • Aside from being one of the first chemistry textbooks, the book was one of the first to state the Law of conservation of mass, define a chemical element, and contain a list of known elements. (wikipedia.org)
  • alchemy
  • Chemistry was preceded by its protoscience, alchemy, which is an intuitive but non-scientific approach to understanding the constituents of matter and their interactions. (wikipedia.org)
  • While both alchemy and chemistry are concerned with matter and its transformations, the crucial difference was given by the scientific method that chemists employed in their work. (wikipedia.org)
  • The word chemistry comes from alchemy, which referred to an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine. (wikipedia.org)
  • paramount
  • A knowledge of environmental soil chemistry is paramount to predicting the fate of contaminants, as well as the processes by which they are initially released into the soil. (wikipedia.org)
  • course
  • It was also during this time that he developed an experimental technique for measuring intramolecular electron transfer rates in proteins, work that would shape the course of Gray lab chemistry for the coming decades. (wikipedia.org)
