If more than one compound be formed from the same two elements,, the difference is shown by prefixing such words as mono-, di-, tri-, sesqui-, per-, sub-, &c., to the last part of the name, or the suffixes -ous and -ic may be appended to the name of the first element.
Japan was thus enriched with two works of very high merit, the Genji Mono galari (c. IO04~ and the Makura no Zoshi (about the same date).
The gauge may be regarded as reduced to its narrowest possible dimensions in mono-rail lines, where the weight of the trains is carried on a single rail.
In the Langen mono-rail the cars are hung from a single overhead rail; a line on this system works between Barmen and Elberfeld, about 9 m., the cars for a portion of the distance being suspended over the river Wupper.
Citric acid, being tribasic, forms either acid monometallic, acid dimetallic or neutral trimetallic salts; thus, mono-, diand tri-potassium and sodium citrates are known.
All four mono-hydroxyxanthones are known, and are prepared by heating salicylic acid with either resorcin, pyrocatechin or hydroquinone; they are yellow crystalline solids, which act as dyestuffs.
Group III.: B, trivalent; Al, trivalent, but possibly also tetra-or penta-valent; Ga, divalent and trivalent; In, mono-, diand tri-valent; Tl, monovalent and trivalent..
Substitution of the Benzene Ring.-As a general rule, homologues and mono-derivatives of benzene react more readily with substituting agents than the parent hydrocarbon; for example, phenol is converted into tribromphenol by the action of bromine water, and into the nitrophenols by dilute nitric acid; similar activity characterizes aniline.
Experience has shown that such mono-derivatives as nitro compounds, sulphonic acids, carboxylic acids, aldehydes, and ketones yield as a general rule chiefly the meta-compounds, and this is independent of the nature of the second group introduced; on the other hand, benzene haloids, amino-, homologous-, and hydroxy-benzenes yield principally a mixture of the orthoand para-compounds.
Toluene or mono-methylbenzene results from the pyrocondensation of a mixture of acetylene and allylene.
Ladenburg's prism admits of one mono-substitution derivative and three di-derivatives.
Bamberger opposed Claus' formula on the following grounds: - The molecule of naphthalene is symmetrical, since 2.7 dioxynaphthalene is readily esterified by methyl iodide and sulphuric acid to a dimethyl ether; and no more than two mono-substitution derivatives are known.
CO 2 Na being thus formed; by continuing the heating under pressure this carbonate gradually changes into mono-sodium salicylate.
The mean values of the relative coagulative powers of sulphates of mono-, di-, and tri-valent metals have been shown experimentally to be approximately in the ratios 1 :35:1023.
The mono-nitro compounds are stable and distil without decomposition; they have a pale yellow colour and possess an agreeable odour.
The mono-nuclear cells are ingesting and digesting many of the polymorpho-nuclear leucocytes.
The history of the illustrated book in Japan may be said to begin with the Ise mono gatari, a romance first published in the 10th century, of which an edition adorned with woodcuts appeared in 1608.
Christiansen found, in an investigation of this kind, that the refractivity of the liquid could only be got to match that of the powder for mono-chromatic light, and that, if white light were used, brilliant colour effects were obtained, which varied in a remarkable manner when small changes occurred in the refractive index of the liquid.
On account of its bearing on the history of the mono syllabic languages of eastern Asia, with their so-called " isolation " or absence of form-words and consequently of grammatical forms. Is the Tibetan a monosyllabic language passing to agglutination, or the reverse?
Acetonyl acetone, CH 3 CO CH 2 CH 2 CO -CH a liquid boiling at 194° C., may be obtained by condensing sodium aceto-acetate with mono-chloracetone (C. Paal, Ber., 1885, 18, p. 59), CH3000H2C1+Na CH [[Coch3(Coor) ->Ch3co Ch2 Ch 000h,(Coor) -Ch3co]] CH2 CH2 000H3; or by the hydrolysis of diaceto-succinic ester, prepared by the action of iodine on sodium aceto-acetate (L.
Numerous mono-, diand trisulphonic acids of a-naphthol are employed in the preparation of azo dyes.
3 On the other hand, the mono ' Or Kathenotheism, a term which did not succeed in gaining permanent support, Hibbert Lect., p. 271.
The mono-benzo-derivatives are coumarone, benzothiophene and indole; the dibenzo-derivatives are diphenylene oxide, dibenzothiophene or diphenylene sulphide, and carbazole.
A mono-, di-, and hexa-hydrate; the latter being the form usually obtained by the solution of the oxide or carbonate in hydrochloric acid.
The following empirical formulae for the stiffness of hempen ropes have been deduced by Mono from the experiments of Coulomb: Let F be the stiffness in pounds avoirdupois; d the diameter of the rope In inches, fl = 48d2 for white ropes and 35d2 for tarred ropes; r the effectire radius of the pulley in inches; T the tension in pounds.
Mono-acetyl resorcin, C 6 H 4 (OH) O 000H 3, is used under the name of "euresol."
As regards the isomerism of the pyridine substitution products, three mono-derivatives are known, the different positions being indicated by the Greek, letters a, s and y, as shown in the inset formula.
The mono-oxypyridines are easily soluble in water and possess only feeble basic properties.
If, however, one of the para positions in the hydrazo compound is substituted, then either diphenyl derivatives or azo compounds are formed, or what is known as the semidine change takes place (P. Jacobson, Berichte, 1892, 2 5, p. 99 2; 1893, 26, p. 681; 1896, 29, p. 2680; Annalen, 1895, 287, p. 97; 1898, 3 0 3, p. 290) A para mono substituted hydrazo compound in the presence of a hydrochloric acid solution of stannous chloride gives either a para diphenyl derivative (the substituent group being eliminated), an ortho-semidine, a para-semidine, or a diphenyl base, whilst a decomposition with the formation of amines may also take place.
South and east of the range the country, apart from that watered by the coast streams, drains to the Mono river.
When two organs can be traced along the same line of descent to one primitive form, that is when they are found to be mono phyletic, their homology is complete; when, however, they are traceable to two primitive forms, though these forms belong to the same morphological series, they are polyphyletic and therefore only incompletely homologous.
Nitrogen), the mono-, diand trioxides being basic in character, the tetraand pentoxides being acidic and also feebly basic. The monoxide, V 2 0, is formed when the metal is oxidized slowly in air.
