It is a bluish-black powder which at high temperatures decomposes into the metal, dioxide and oxygen.
It decomposes steam at a red heat, and slowly dissolves in dilute hydrochloric and sulphuric acids, but more readily in nitric acid.
Hot concentrated sulphuric acid also decomposes allantoin, with production of ammonia, and carbon monoxide and dioxide.
This body is being continually formed in the yeast cell, and decomposes the sugar which has diffused into the cell.
The Bacterium acidi lacti described by Pasteur decomposes milk sugar into lactic acid.
Bacillus amylobacter usually accompanies the lactic acid organism, and decomposes lactic and other higher acids with formation of butyric acid.
It dissolves readily in water and the aqueous solution decomposes on standing; a dark-brown flocculent precipitate of azulmic acid, C 4 H 5 N 5 0, separating whilst ammonium oxalate, urea and hydrocyanic acid are found in the solution.
Decomposes them, with elimination of nitrogen and the formation of the corresponding acid, RCOï¿½NH 2 +[[Onoh = Rï¿½Cooh]]+N2-f-H20.
It reduces many metallic oxides, such as lead monoxide and cupric oxide, and decomposes water at a red heat.
A saturated solution of the gas, in water, is a colourless, oily, strongly fuming liquid which after a time decomposes, with separation of metaboric acid, leaving hydrofluoboric acid HF BF3 in solution.
It is insoluble in water and unaffected by most reagents, but when heated in a current of steam or boiled for some time with a caustic alkali, slowly decomposes with evolution of ammonia and the formation of boron trioxide or an alkaline borate; it dissolves slowly in hydrofluoric acid.
Borimide B 2 (NH) 3 is obtained on long heating of the compound B 2 S 3.6NH 3 in a stream of hydrogen, or ammonia gas at 115-120° C. It is a white solid which decomposes on heating into boron nitride and ammonia.
Long-continued heating with water also decomposes it slowly.
A pentasulphide B2S5 is prepared, in an impure condition, by heating a solution of sulphur in carbon bisulphide with boron iodide, and forms a white crystalline powder which decomposes under the influence of water into sulphur, sulphuretted hydrogen and boric acid.
It decomposes water slowly in the cold, and more rapidly on heating.
On fusion with solid potash at 250° C. it completely decomposes, giving potassium oxalate and hydrogen, C2H602-1-2KHO =K2C204+4H2.
Cadmium vapour decomposes water at a red heat, with liberation of hydrogen, and formation of the oxide of the metal.
Concentrated sulphuric acid also decomposes it: H 2 SO 4 +H 2 S = 2H 2 0 +S02+S.
It combines with many metals to form sulphides, and also decomposes many metallic salts with consequent production of sulphides, a property which renders it extremely useful in chemical analysis.
It may be condensed and yields a solid which melts at - 55° C. Sulphuretted hydrogen decomposes it with formation of hydrofluoric acid and liberation of sulphur.
Water decomposes it violently with formation of hydrochloric and sulphurous acids.
Water decomposes it into hydrochloric and sulphurous acids.
It is a colourless fuming liquid which boils at 152-153° C. When heated under pressure it decomposes, forming sulphuric acid, sulphuryl chloride, &c. (Ruff, Ber., 1901, 34, p. 35 0 9).
It is unstable at ordinary temperatures and rapidly decomposes into its generators on warming.
It slowly decomposes on exposure or on heating.
The historian evidently decomposes Alexander's power into the components: Talleyrand, Chateaubriand, and the rest--but the sum of the components, that is, the interactions of Chateaubriand, Talleyrand, Madame de Stael, and the others, evidently does not equal the resultant, namely the phenomenon of millions of Frenchmen submitting to the Bourbons.
