In organic chemistry, an ethyl group (abbr. Et) is an alkyl substituent with the formula −CH 2 CH 3, derived from ethane (C 2 H 6). Ethyl is used in the International Union of Pure and Applied Chemistry 's nomenclature of organic chemistry for a saturated two-carbon moiety in a molecule, while the prefix " eth- " is used to indicate the ...
The Swiss Federal Laboratories for Materials Science and Technology (Empa; German: Eidgenössische Materialprüfungs- und Forschungsanstalt, [2] French: Laboratoire fédéral d’essai des matériaux et de recherche, Italian: Laboratorio federale di prova dei materiali e di ricerca, Romansh: Institut federal da controlla da material e da perscrutaziun,) is a Swiss research institution for ...
The chlorohydrin process allows to reach 95% conversion of ethylene chlorohydrin. The yield of ethylene oxide is about 80% of the theoretical value; for 1 tonne (0.98 long tons; 1.1 short tons) of ethylene oxide, about 200 kg (440 lb) of ethylene dichloride is produced. [ 68 ]
The process to obtain any of the degrees is very similar, with minor changes. Any PhD holder can submit a habilitation thesis to obtain the degree. For agregação , the thesis is composed by a detailed CV of the achievements obtained after concluding the PhD, a detailed report of an academic course taught at the university (or a proposed ...
Chemistry education An active area of research within both the disciplines of chemistry and education. The main focus of research is on learning and teaching of chemistry in schools, colleges and universities. The practice of chemical education is teaching chemistry to students and the training of teachers to teach chemistry.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics. This article contains the list of certain mnemonics in chemistry.
