H3O.Hydrogen trioxide. Mono-1di di- 1. Prefix meaning two, twice. 2. chemistry Often used in place of bis- when not likely to be confusing; e.g., dichloro compounds. Definition for di (6 of 9) a prefix occurring in loanwords from Greek, where it meant “two,” “twice,” “double” (diphthong); on this model, freely used in the formation of compound words (dicotyledon; dipolar) and in chemical terms (diatomic; disulfide).

Due to its implications for both dose level and frequency, clearance rate is one of the most important pharmacokinetic parameters to consider in the design of drug candidates. Clearance can be classified into three general categories, namely, metabolic transformation, renal excretion, and hepatobiliary excretion. Within each category, there are a host of biochemical and physiological What is chemistry? Simply put, chemistry is the study of the interactions of matter with other matter and with energy. This seems straightforward enough.

Ortho, meta, and para historically carried different meanings, but in 1879 the American Chemical Society settled upon the following definitions, which remain in use today. Small functional siloxane units have gained great interest as molecular model systems for mimicking more complex silicate structures both in nature and in materials chemistry.

Being able to describe the ingredients in a cake and how they change when the cake is baked is called chemistry. iv) If there are two or more same type of simple substituents they should be prefixed by di, tri, tetra, penta etc. E.g. The number of methyl groups are indicated by di and tri in the following cases. v) If the side chains themselves contain terms like di, tri, tetra etc., the multiplying prefixes like bis, tris, tetrakis etc., should be used. E.g. Chemistry Meta your communities .
