Metathesis (linguistics), alteration of the order of phonemes within a word Quantitative metathesis , exchange of long and short roles, without changing order of vowel sounds Chemical change in which a pair of molecules exchange electronic patterns of bonding
The likely cause for metathesis in the word "hospital" is that the result resembles a common word pattern familiar to Arabic speakers (namely a Form X verbal noun). Perhaps the clearest example of metathesis in Egyptian Arabic is the modern name of the city of Alexandria : ( Al- ) Iskandariya ( الإسكندرية ).
A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species which results in the creation of products with similar or identical bonding affiliations. [1] This reaction is represented by the general scheme: + +
Certain words in Proto-Indo-European had two vowels separated by the consonant s or y (esu "good"). In Greek, this consonant changed to h ( ehu ), and was lost between vowels ( eu ). In Homer , the two vowels were sometimes pronounced separately (diaeresis: ἐΰ ) and sometimes together (synaeresis: εὖ ).
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 ...
In organic chemistry, olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. [ 1 ] [ 2 ] Because of the relative simplicity of olefin metathesis, it often creates fewer undesired by-products and hazardous wastes than alternative ...
The word aqueous (which comes from aqua) means pertaining to, related to, similar to, or dissolved in, water. [1] [2] As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry. Since water is frequently used as the solvent in experiments, the word solution refers to an aqueous solution, unless the ...
I think the mention of the meaning of metathesis in chemistry is redundant due to the fact that it is mentioned in the disambiguation. The statement in the article ought to be deleted. The first sentence of the linked scientific paper is plausibly useful -- and on-point: "Derived from the Greek words meta (change) and thesis (position ...
