Molendinaceous :: Molendinaceous (a.) Alt. of Molendinariou.

Atomicity :: Atomicity (n.) Degree of atomic attraction; equivalence; valence; also (a later use) the number of atoms in an elementary molecule. See Valence.

Bisulphide :: Bisulphide (n.) A sulphide having two atoms of sulphur in the molecule; a disulphide, as in iron pyrites, FeS2; -- less frequently called bisulphuret..

Absorption :: Absorption (n.) An imbibing or reception by molecular or chemical action; as, the absorption of light, heat, electricity, etc..

Ornithorhynchus :: Ornithorhynchus (n.) See Duck mole, under Duck..

Heptane :: Heptane (n.) Any one of several isometric hydrocarbons, C7H16, of the paraffin series (nine are possible, four are known); -- so called because the molecule has seven carbon atoms. Specifically, a colorless liquid, found as a constituent of petroleum, in the tar oil of cannel coal, etc..

Zokor :: Zokor (n.) An Asiatic burrowing rodent (Siphneus aspalax) resembling the mole rat. It is native of the Altai Mountains.

Septimole :: Septimole (n.) A group of seven notes to be played in the time of four or six.

Tetracid :: Tetracid (a.) Capable of neutralizing four molecules of a monobasic acid; having four hydrogen atoms capable of replacement ba acids or acid atoms; -- said of certain bases; thus, erythrine, C4H6(OH)4, is a tetracid alcohol..

Corpuscle :: Corpuscle (n.) A minute particle; an atom; a molecule.

Alum :: Alum (n.) A double sulphate formed of aluminium and some other element (esp. an alkali metal) or of aluminium. It has twenty-four molecules of water of crystallization.

Annicut :: Annicut (n.) A dam or mole made in the course of a stream for the purpose of regulating the flow of a system of irrigation.

Palmitin :: Palmitin (n.) A solid crystallizable fat, found abundantly in animals and in vegetables. It occurs mixed with stearin and olein in the fat of animal tissues, with olein and butyrin in butter, with olein in olive oil, etc. Chemically, it is a glyceride of palmitic acid, three molecules of palmitic acid being united to one molecule of glyceryl, and hence it is technically called tripalmitin, or glyceryl tripalmitate..

Ozone :: Ozone (n.) A colorless gaseous substance (O/) obtained (as by the silent discharge of electricity in oxygen) as an allotropic form of oxygen, containing three atoms in the molecule. It is a streng oxidizer, and probably exists in the air, though by he ordinary tests it is liable to be confused with certain other substances, as hydrogen dioxide, or certain oxides of nitrogen. It derives its name from its peculiar odor, which resembles that of weak chlorine..

Mole :: Mole (n.) A spot, mark, or small permanent protuberance on the human body; esp., a spot which is dark-colored, from which commonly issue one or more hairs..

Chemistry :: Chemistry (n.) That branch of science which treats of the composition of substances, and of the changes which they undergo in consequence of alterations in the constitution of the molecules, which depend upon variations of the number, kind, or mode of arrangement, of the constituent atoms. These atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained. Chemistry deals with the changes in the composition and constitution of molecules. See Atom, Molecul

Repulsion :: Repulsion (n.) The power, either inherent or due to some physical action, by which bodies, or the particles of bodies, are made to recede from each other, or to resist each other's nearer approach; as, molecular repulsion; electrical repulsion..
