Lern More About Mole

Polychloride :: Polychloride (n.) A chloride containing more than one atom of chlorine in the molecule.
Tripalmitate :: Tripalmitate (n.) A palmitate derived from three molecules of palmitic acid.
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..
Molested :: Molested (imp. & p. p.) of Moles.
Tetrol :: Tetrol (n.) A hypothetical hydrocarbon, C4H4, analogous to benzene; -- so called from the four carbon atoms in the molecule..
Swanskin :: Swans-down (n.) A fine, soft, thick cloth of wool mixed with silk or cotton; a sort of twilled fustian, like moleskin..
Dicalcic :: Dicalcic (a.) Having two atoms or equivalents of calcium to the molecule.
Necrosis :: Necrosis (n.) Mortification or gangrene of bone, or the death of a bone or portion of a bone in mass, as opposed to its death by molecular disintegration. See Caries..
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..
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
Molecule :: Molecule (n.) A group of atoms so united and combined by chemical affinity that they form a complete, integrated whole, being the smallest portion of any particular compound that can exist in a free state; as, a molecule of water consists of two atoms of hydrogen and one of oxygen. Cf. Atom..
Invertin :: Invertin (n.) An unorganized ferment which causes cane sugar to take up a molecule of water and be converted into invert sugar.
Myrmicine :: Myrmicine (a.) Of or pertaining to Myrmica, a genus of ants including the small house ant (M. molesta), and many others..
Polyatomic :: Polyatomic (a.) Having more than one atom in the molecule; consisting of several atoms.
Microcrith :: Microcrith (n.) The weight of the half hydrogen molecule, or of the hydrogen atom, taken as the standard in comparing the atomic weights of the elements; thus, an atom of oxygen weighs sixteen microcriths. See Crith..
Infesttation :: Infesttation (n.) The act of infesting or state of being infested; molestation; vexation; annoyance.
Hexeikosane :: Hexeikosane (n.) A hydrocarbon, C26H54, resembling paraffine; -- so called because each molecule has twenty-six atoms of carbon..
Osmose :: Osmose (n.) The tendency in fluids to mix, or become equably diffused, when in contact. It was first observed between fluids of differing densities, and as taking place through a membrane or an intervening porous structure. The more rapid flow from the thinner to the thicker fluid was then called endosmose, and the opposite, slower current, exosmose. Both are, however, results of the same force. Osmose may be regarded as a form of molecular attraction, allied to that of adhesion..
Disulphuric :: Disulphuric (a.) Applied to an acid having in each molecule two atoms of sulphur in the higher state of oxidation.
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..
