Pentacid :: Pentacid (a.) Capable of neutralizing, or combining with, five molecules of a monobasic acid; having five hydrogen atoms capable of substitution by acid residues; -- said of certain complex bases..
Tetrabasic :: Tetrabasic (a.) Capable of neutralizing four molecules of a monacid base; having four hydrogen atoms capable of replacement by bases; quadribasic; -- said of certain acids; thus, normal silicic acid, Si(OH)4, is a tetrabasic acid..
Hexane :: Hexane (n.) Any one of five hydrocarbons, C6H14, of the paraffin series. They are colorless, volatile liquids, and are so called because the molecule has six carbon atoms..
Plastidule :: Plastidule (n.) One of the small particles or organic molecules of protoplasm.
Diselenide :: Diselenide (n.) A selenide containing two atoms of selenium in each molecule.
Tetrol :: Tetrol (n.) A hypothetical hydrocarbon, C4H4, analogous to benzene; -- so called from the four carbon atoms in the molecule..
Polybasic :: Polybasic (a.) Capable of neutralizing, or of combining with, several molecules of a monacid base; having several hydrogen atoms capable of being replaced by basic radicals; -- said of certain acids; as, sulphuric acid is polybasic..
Quartane :: Quartane (n.) Butane, each molecule of which has four carbon atoms..
Polysilicic :: Polysilicic (a.) Of or pertaining to compounds formed by the condensation of two or more molecules of silicic acid.
Vacuist :: Vacuist (n.) One who holds the doctrine that the space between the bodies of the universe, or the molecules and atoms of matter., is a vacuum; -- opposed to plenist..
Atomicity :: Atomicity (n.) Degree of atomic attraction; equivalence; valence; also (a later use) the number of atoms in an elementary molecule. See Valence.
Tetratomic :: Tetratomic (a.) Consisting of four atoms; having four atoms in the molecule, as phosphorus and arsenic..
Protosilicate :: Protosilicate (n.) A silicate formed with the lowest proportion of silicic acid, or having but one atom of silicon in the molecule..
Dioxide :: Dioxide (n.) An oxide containing two atoms of oxygen in each molecule; binoxide.
Nonane :: Nonane (n.) One of a group of metameric hydrocarbons C9H20 of the paraffin series; -- so called because of the nine carbon atoms in the molecule. Normal nonane is a colorless volatile liquid, an ingredient of ordinary kerosene..
Corpuscle :: Corpuscle (n.) A minute particle; an atom; a molecule.
Triacid :: Triacid (a.) Capable of neutralizing three molecules of a monobasic acid or the equivalent; having three hydrogen atoms which may be acid radicals; -- said of certain bases; thus, glycerin is a triacid base..
Molecule :: Molecule (n.) One of the very small invisible particles of which all matter is supposed to consist.
Pentatomic :: Pentatomic (a.) Having five atoms in the molecule.
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..
