clinique 3 step type 3


On heating they yield phosphine and leave a residue of pyrophosphate, or a mixture of metaand pyrophosphates, with a little phosphorus. A year or two later field trials were begun in England, with the final result that basic slag has become recognized as a valuable source of phosphorus for growing crops, and is now in constant demand for application to the soil as a fertilizer. Thorpe's investigation of the products of the slow combustion of phosphorus. (554° F.), it is produced in the form of vapour, which, mingled with carbon monoxide, passes to the condenser, where it is condensed. Phosphate requirement The target index for soil phosphorus is Index 2 (16-25 mg/litre ). The tertiary phosphines are characterized by their readiness to pass into derivatives containing pentavalent phosphorus, and consequently they form addition compounds with sulphur, carbon bisulphide, chlorine, bromine, the halogen acids and the alkyl halides with great readiness. 2. CH:C(CH 3) 2, forms yellow crystals which melt at 28° C. and boil at 197.2° C. When heated with phosphorus pentoxide it yields acetone, water and some pseudocumene. Several allotropic forms of phosphorus have been described, and in recent years much work has been done towards settling their identities. 8 % , using phosphorus oxychloride as the chlorinating agent. Phenyl salicylate, C6H4(OH) C 02C6H5, or salol, is obtained by heating salicylic acid, phenol and phosphorus oxychloride to 120-125° C.; by heating salicylic acid to 2 =0° C.; or by heating salicyl metaphosphoric acid and phenol to 140-150° C. (German Patent 85,565). Phosphorus pentachloride decomposes it into carbon monoxide and dioxide, the reaction being the one generally applied for the purpose of preparing phosphorus oxychloride. In the basic Bessemer process phosphorus is readily removed by oxidation, because the product of its oxidation, phosphoric acid, P 2 O 5, in the presence of an excess of base forms stable phosphates of lime and iron which pass into the slag, making it valuable as an artificial manure. All Rights Reserved. It is the carboxylic acid corresponding to tropine, for it yields the same products on oxidation, and by treatment with phosphorus pentachloride is converted into anhydroecgonine, C9H13N02, which, when heated to 280° C. with hydrochloric acid, splits out carbon dioxide and yields tropidine, C8H13N. Phosphorus containing albumins (nucleo-albumins), caseins, vitellines, nucleo-albumins of the cellprotoplasm, mucoid nucleo-albumins. It combines directly with sulphur and phosphorus, and is readily oxidized when heated with metallic oxides (such as litharge, mercuric oxide, manganese dioxide, &c.). A small quantity of the phosphorus combines with the oxygen in the vessel, and after this the operation is practically conducted in an atmosphere of nitrogen with the additional safety from any risk of explosion. It is decomposed by water, and with a solution of yellow phosphorus in carbon bisulphide it gives a red powder of composition PBI 2, which sublimes in vacuo at 210° C. to red crystals, and when heated in a current of hydrogen loses its iodine and leaves a residue of boron phosphide PB. Phosphorus suboxide, P 4 O, is said to be formed, mixed with the other oxides, when the element is burnt in a limited supply of air or in pure oxygen under reduced pressure (E. The oxide P 2 0 was obtained by Besson (Comptes rendus, 1897, 124, p. 763; 1901, pp. The maize crop was in its second year, weeds were being stopped, and the Inga was recycling nutrients, including phosphorus. Beyond this sulphur and phosphorus can be removed in the electric furnace, whereas in the crucible process they cannot. It does not dissociate on heating as do the pentachloride and pentabromide, thus indicating the existence of pentavalent phosphorus in a gaseous compound; dissociation, however, into the trifluoride and free fluorine may be brought about by induction sparks of 150 to 200 mm. It is the carboxylic acid corresponding to tropine, for it yields the same products on oxidation, and by treatment with phosphorus pentachloride is converted into anhydroecgonine, C9H13N02, which, when heated to 280° C. with hydrochloric acid, splits out carbon dioxide and yields tropidine, C8H13N. Fe2P3 is prepared by the action of phosphorus iodide vapour on reduced iron. As the iron oxide is stirred into the molten metal laboriously by the workman or "puddler " with his hook or "rabble," it oxidizes the silicon to silica and the phosphorus to phosphoric acid, and unites with both these products, forming with them a basic iron silicate rich in phosphorus, called " puddling " or " tap cinder.". Examples of 'phosphorus' in a sentence phosphorus. by the addition of sulphuretted hydrogen to the nitriles, or by the action of phosphorus pentasulphide on the acid-amides. The " phospho-glyco-proteids " resemble the mucins and mucoids in containing a carbohydrate residue, but differ in containing phosphorus. The removal of phosphorus, a very important duty of the puddling process, requires that the cinder shall be " basic," i.e. Moissan); it has been liquefied, the liquid also being of a yellow colour and boiling at - 187° C. It is the most active of all the chemical elements; in contact with hydrogen combination takes place between the two gases with explosive violence, even in the dark, and at as low a temperature as - 210 C.; finely divided carbon burns in the gas, forming carbon tetrafluoride; water is decomposed even at ordinary temperatures, with the formation of hydrofluoric acid and "ozonised" oxygen; iodine, sulphur and phosphorus melt and then inflame in the gas; it liberates chlorine from chlorides, and combines with most metals instantaneously to form fluorides; it does not, however, combine with oxygen. Translations of the phrase ELEMENTAL PHOSPHORUS from english to spanish and examples of the use of "ELEMENTAL PHOSPHORUS" in a sentence with their translations: Elemental phosphorus is a highly reactive substance. The specific effect of phosphorus is to make the metal cold-short, i.e. Numerous hydrides are known; heated with red phosphorus and hydriodic acid the hydrocarbon yields mixtures of hydrides of composition C10H10 to C10H20. Annuals, as a general rule , are very responsive to phosphorus fertilization. The Curies showed that oxygen was convertible into ozone, and Sudborough that yellow phosphorus gave the red modification when submitted to their influence. He applied himself more particularly to the oxygen compounds, and determined with a fair degree of accuracy the ratio of carbon to oxygen in carbon dioxide, but his values for the ratio of hydrogen to oxygen in water, and of phosphorus to oxygen in phosphoric acid, are only approximate; he introduced no new methods either for the estimation or separation of the metals. 761), and also when a solution of phosphorus in the trichloride or tribromide is exposed to light. Arsenic trichloride, AsCl3, is prepared by distilling white arsenic with concentrated sulphuric acid and common salt, or by the direct union of arsenic with chlorine, or from the action of phosphorus pentachloride on white arsenic. Thiophosphoryl chloride, PSC1 3, may be obtained by the direct combination of sulphur with the trichloride; from sulphuretted hydrogen and the pentachloride; from antimony trisulphide and the pentachloride; by heating the pentasulphide with the pentachloride; and by dissolving phosphorus in sulphur chloride and distilling the solution: 2P+3S 2 C1 2 = 4S+2PSC1 3. It is comparatively stable up to 200°, but when heated in a sealed tube to 440° it gives phosphorus and the tetroxide P204. It combines readily with fluorine, chlorine and bromine, and also with sulphur, selenium, phosphorus, &c. Reduction by means of hydriodic acid and phosphorus at 140° C. gives toluene, whilst on distillation with alcoholic potash, toluene and benzoic acid are formed. Copyright © 2020 LoveToKnow. Taking as types hydrogen, hydrochloric acid, water and ammonia, he postulated that all organic compounds were referable to these four forms: the hydrogen type included hydrocarbons, aldehydes and ketones; the hydrochloric acid type, the chlorides, bromides and iodides; the water type, the alcohols, ethers, monobasic acids, acid anhydrides, and the analogous sulphur compounds; and the ammonia type, the amines, acid-amides, and the analogous phosphorus and arsenic compounds. By the action of sodium amalgam on an alcoholic solution of anthracene, an anthracene dihydride, C14H12, is obtained, whilst by the use of stronger reducing agents, such as hydriodic acid and amorphous phosphorus, hydrides of composition C14H16 and C14H24 are produced. Stock (Ber., 1909, 42, 4510), who points out that ordinary red phosphorus melts at 605°-610°, whilst Hittorf's melts at 620°; moreover, the latter is less reactive than the former at high temperatures. Thus workers in lead suffer from the effects of this substance as a poison, those who work in phosphorus are liable to necrosis of bone and fatty degeneration of the blood vessels and organs, and the many occupations in which dust is inhaled (coalmining, stone-dressing, steel-polishing, &c.; fig. 132, 1556) by heating a mixture of phosphonium bromide and phosphorus oxychoride in sealed tubes to 50°. Similarly, phosphorus can be burned under water by covering it with a little potassium chlorate and running in a thin stream of concentrated sulphuric acid (see papers by Bray, Zeit. Translations of the phrase INCLUDING PHOSPHORUS from english to spanish and examples of the use of "INCLUDING PHOSPHORUS" in a sentence with their translations: Better nutrient uptake including phosphorus , copper, zinc and manganese. Oxidation with ferric chloride converts it into dicarvacrol, whilst phosphorus pentachloride transforms it into chlorcymol. Long digestion of the acid with excess of phosphorus pentachloride results in the formation of the acid chloride, C 6 (0001),, which crystallizes in needles, melting at 190° C. By heating the ammonium salt of the acid to 150-160° C. as long as ammonia is evolved, a mixture of CO paramide (mellimide), C6 (CO > NH) 3, and ammonium euchroate is obtained. It may also be obtained by distilling nitric acid over phosphorus pentoxide. total phosphorus in a sentence - Use "total phosphorus" in a sentence 1. The quantity of phosphorus in the pig iron is usually known accurately, and the dephosphorization takes place so regularly that the quantity of air which it needs can be foretold closely. radioactive phosphorus (32P) may be used to treat ET. Sodium and boiling amyl alcohol reduce it to a tetrahydroretene, - t whilst if it be heated with phosphorus and hydriodic acid to 260° C. a dodecahydride is formed. At a relatively low temperature, say 1300° C., the phosphorus of cast iron oxidizes and is removed much faster than its carbon, while at a higher temperature, say 1500° C., carbon oxidizes in preference to phosphorus. When heated with hydriodic acid and phosphorus it forms phenylacetic acid; whilst concentrated hydrobromic acid and hydrochloric acid at moderate temperatures convert it into phenylbromand phenylchlor-acetic acids. Succinyl chloride, obtained by the action of phosphorus pentachloride on succinic acid, is a colourless liquid which boils at 190° C. In many respects it behaves as though it were dichlorbutyro-lactone, /CC12 C 2 He >O; e.g. In the first stage the phosphorus is removed from the molten steel by oxidizing it to phosphoric acid, P205, by means of iron oxide contained in a molten slag very rich in lime, and hence very basic and retentive of that phosphoric acid. Nearly all the ore is magnetite, and in the midlands it is almost wholly free of phosphorus. 2. Considerable interest is attached to the remarkable series of hydrocarbons obtained by Gomberg (Ber., 1900, 33, p. 3150, et seq.) The discovery of phosphorus by Brand, a Hamburg alchemist, in 1669 excited chemists to an unwonted degree; it was also independently prepared by Robert Boyle and J. Retardex materials can be recycled and the PP compounds containing phosphorus flame retardants retain their flame retardant properties. Of other phosphorus compounds we may here notice Gengembre's discovery of phosphuretted hydrogen (phosphine) in 1783, the analogy of which to ammonia was first pointed out by Davy and supported at a later date by H. By the action of phosphorus pentachloride, the hydroxyl group is replaced by chlorine. The olefines may be synthetically prepared by eliminating water from the alcohols of the general formula CnH2n+1 OH, using sulphuric acid or zinc chloride generally as the dehydrating agent, although phosphorus pentoxide, syrupy phosphoric acid and anhydrous oxalic acid may frequently be substituted. Translations of the phrase TOTAL PHOSPHORUS from english to spanish and examples of the use of "TOTAL PHOSPHORUS" in a sentence with their translations: Total phosphorus : organic and inorganic. Phosphorus chlorides give acid chlorides, R�CO�C1, the hydroxyl group being replaced by chlorine, and acid anhydrides, (R�CO) 2 0, a molecule of water being split off between two carboxyl groups. Alloys prepared in this way, and known as phosphor bronze, may contain only about 1% of phosphorus in the ingot, reduced to a mere trace after casting, but their value is nevertheless enhanced for purposes in which a hard strong metal is required, as for pump plungers, valves, the bushes of bearings, &c. Bronze again is improved by the presence of manganese in small quantity, and various grades of manganese bronze, in some of which there is little or no tin but a considerable percentage of zinc, are extensively used in mechanical engineering. They glow with some kind of phosphorus. Phosphorus pentasulphide at 140 - I 50° C. converts it into xanthion by transformation of > CO to > CS (R. His terminology was vague and provoked caustic criticism from Berzelius; he assumed that all molecules contained two atoms, and consequently the atomic weights deduced from vapour density determinations of sulphur, mercury, arsenic, and phosphorus were quite different from those established by gravimetric and other methods. Disulphuryl chloride, S 2 O 5 C1 2, corresponding to pyrosulphuric acid, is obtained by the action of sulphur trioxide on sulphur dichloride, phosphorus oxychloride, sulphuryl chloride or dry sodium chloride: 650 3- + 2POC1 3 = P 2 O 5 + 3S 2 O 5 C1 2; S2C12+ 5503 = S 2 0 5 C1 2 + 550 2; SO 3 + SO 2 C1 2 = S 2 0 5 C1 2; 2NaC1 + 3SO 3 = S 2 0 5 C1 2 -1 Na 2 SO 4. It is well to remove this latter element early, so that when the carbon shall have fallen to the proportion which the steel is to contain, the steel shall already be free from phosphorus, and so ready to cast. Phosphorus tribromide, PBr 3, prepared by mixing solutions of its elements in carbon disulphide and distilling, is a transparent, mobile liquid, boiling at 173° and resembling the trichloride chemically. Since conhydrine is dehydrated by phosphorus pentoxide into a mixture of a and f3 coniceines, it may be considered an oxyconine. in a sealed tube pentamethylene dichloride is obtained, and this on treatment with potassium phthalimide gives a condensation product of composition, C 6 H 4 [CO] 2 N(CH 2) 5 N[CO] 2 C 6 H 4, which is finally hydrolysed by hydrochloric acid. Phenyl salicylate, C6H4(OH) C 02C6H5, or salol, is obtained by heating salicylic acid, phenol and phosphorus oxychloride to 120-125° C.; by heating salicylic acid to 2 =0° C.; or by heating salicyl metaphosphoric acid and phenol to 140-150° C. (German Patent 85,565). When heated with phosphorus pentoxide it yields cyanogen. 2. Phosphorus quickly illuminated the space, but they saw. Most people chose this as the best definition of phosphorus: Phosphorus is a poisonous... See the dictionary meaning, pronunciation, and sentence examples. The pentabromide, PBr 5, which results from phosphorus and an excess of bromine, is a yellow solid, and closely resembles the pentachloride. As phosphorus boils at 2 9 0°C. It is not reduced by hydriodic acid and phosphorus, but sodium in the presence of amyl alcohol reduces it to tetrahydrodiphenyl C12H14. OH(3), is formed when thymol (paraisopropyl-meta-cresol) is heated with phosphorus pentoxide. It may be prepared by distilling fuming sulphuric acid, or concentrated sulphuric acid over phosphorus pentoxide, or by the direct union of sulphur dioxide with oxygen in the presence of a catalyst, such as platinized asbestos (see Sulphuric Acid). It has no action on glass in the cold, but when heated it gives phosphorus and silicon tetrafluoride. Calcium and phosphorus in milk serve to feed nanobacteria, causing calcification and cancer. The oxidation with nitric acid in sealed tubes at a temperature of 150° to 200° for aliphatic compounds, and 250° to 260° for aromatic compounds, is in common use, for both the sulphur and phosphorus can be estimated, the former being oxidized to sulphuric acid and the latter to phosphoric acid. Iron and phosphorus unite to form a solid solution which breaks up on cooling into a pearlite. More important is the so-called " red phosphorus," which is produced by heating yellow phosphorus to about 230 for 24 hours in an inert atmosphere, or in closed vessels to 300°, when the change is effected in a few minutes. It is a thick oil which sets at - 20° C. to a mass of crystals of melting point o C, and boiling point 236-237°C. Theoretical speculations were revived by Lavoisier, who, having explained the nature of combustion and determined methods for analysing compounds, concluded that vegetable substances ordinarily contained carbon, hydrogen and oxygen, while animal substances generally contained, in addition to these elements, nitrogen, and sometimes phosphorus and sulphur. He explained and simplified the process of obtaining phosphorus from urine, and made some admirable observations on phosphoric acid; but though he noted the increase in weight that attends the conversion of phosphorus into phosphoric acid he was content to remain an adherent of the phlogistic doctrine. When taken by the mouth phosphorus is an irritant poison in large doses; in small doses the only effects noticeable consist in an increased formation of bony and connective tissue, although it is also supposed to exert a gently stimulating effect upon the nervous system. The action of bromine is sometimes accelerated by the use of compounds which behave catalytically, the more important of these substances being iodine, iron, ferric chloride, ferric bromide, aluminium bromide and phosphorus. In the United States a committee of the American Society of Civil Engineers, appointed to consider the question of rail manufacture in consequence of an increase in the number of rail-failures, issued an interim report in 1907 in which it suggested a range of carbon from 0-55 to 0-65% for the heaviest sections of Bessemer steel flange rails, with a phosphorus maximum of 0.085%; while the specifications of the American Society for Testing Materials, current at the same period, put the carbon limits at o 45 to 0-55%, and the phosphorus limit at o io. Phosphorus tribromide, PBr 3, prepared by mixing solutions of its elements in carbon disulphide and distilling, is a transparent, mobile liquid, boiling at 173° and resembling the trichloride chemically. Ann., 1832, 24, p. 151) from phosphine and hydrobromic acid; it also results when phosphorus is heated with hydrobromic acid to 100120° C. in sealed tubes (Damoiseau, Bull. Phthalyl chloride with phosphorus pentachloride gives two phthalylene tetrachlorides, one melting at 88° and the other at 47°. Examples of amount of phosphorus in a sentence, how to use it. Phosphorus trifluorodichloride, PF3C12, prepared from chlorine and the trifluoride, is a pungentsmelling gas, which at 250° gives the pentachloride and fluoride. Braun (Ber., 1904, 37, p. 35 8 3) has prepared pentamethylene derivatives from piperidine by the action of phosphorus pentachloride. phosphorus, the absorbing bulb has a tubulure at the bottom. phosphorus used in many matches made the factory workers who produced them ill. Plants use the sunâs energy to fix carbon by photosynthesis and dissolved phosphorus and nitrogen to help build proteins. The first is formed when 30% hydrogen peroxide reacts with phosphorus pentoxide or metaor pyrophosphoric acids at low temperatures and the mixture diluted with ice-cold water. Phosphoryl trifluoride, POF3, may be obtained by exploding 2 volumes of phosphorus trifluoride with 1 volume of oxygen (Moissan, 1886); by heating 2 parts of finely-divided cryolite and 3 parts of phosphorus pentoxide (Thorpe and Hambly, Jour. The ebullition from the formation of carbonic oxide puffs up the resultant phosphoric slag enough to make most of it run out of the furnace, thus both removing the phosphorus permanently from danger of being later deoxidized and returned to the steel, and partly freeing the bath of metal from the heat-insulating blanket of slag. His perception of the analogy between it and ammonia led to his famous work on the amines and ammonium bases and the allied organic phosphorus compounds, while his researches on rosaniline, which he first prepared in 1858, formed the first of a series of investigations on colouring matters which only ended with quinoline red in 1887. They did not necessarily establish phosphorus as a new element. Phosphorus and boron act as glass flow temperature modifiers. Calcium carbide, graphite, phosphorus and carborundum are now extensively manufactured by the operations outlined above. He burned phosphorus in air standing over mercury, and showed that (1) there was a limit to the amount of phosphorus which could be burned in the confined air, (2) that when no more phosphorus could be burned, one-fifth of the air had disappeared, (3) that the weight of the air lost was nearly equal to the difference in the weights of the white solid produced and the phosphorus burned, (4) that the density … Sodium amalgam reduces them to secondary alcohols; phosphorus pentachloride replaces the carbonyl oxygen by chlorine, forming the ketone chlorides. According to Abel, the most favourable effect is produced by from I to 12% of phosphorus. Over 100,000 German translations of English words and phrases. In the former the silicon and part of the carbon are moved rapidly, in the latter the rest of the carbon and the phosphorus are removed slowly, and the metal is brought accurately to the proper temperature and composition. The atomic weight of phosphorus was determined by Berzelius, Pelouze, Jacquelin, Dumas, Schrotter, Brodie and van der Plaats. It slowly reacts with cold water to form phosphorous acid; but with hot water it is energetically decomposed, giving much red phosphorus or the suboxide being formed with an explosive evolution of spontaneously inflammable phosphoretted hydrogen; phosphoric acid is also formed. The reason for this is that in it the slag, by means of which all the purification must needs be done, is not heated effectively; that hence it is not readily made thoroughly liquid; that hence the removal of the phosphoric slag made in the early dephosphorizing stage of the process is liable to be incomplete; and that hence, finally, the phosphorus of any of this slag which is left in the furnace becomes deoxidized during the second or deoxidizing stage, and is thereby returned to befoul the underlying steel. The old French oil of turpentine is the best antidote to use in phosphorus poisoning, delaying the toxic effects; but ordinary oils are not only useless but harmful. When heated with hydriodic acid and phosphorus to 200° C. it yields a hexahydride. phosphorus is a nutrient used in fertilizer that helps plants grow: 8. It behaves as a strong acid and on treatment with phosphorus pentachloride at high temperatures gives triazole. On oxidation it gives triphenylcarbinol, (C 6 H 5) 3 C OH, and reduction with hydriodic acid and red phosphorus gives benzene and toluene. They do not represent the opinions of YourDictionary.com. in a sealed tube pentamethylene dichloride is obtained, and this on treatment with potassium phthalimide gives a condensation product of composition, C 6 H 4 [CO] 2 N(CH 2) 5 N[CO] 2 C 6 H 4, which is finally hydrolysed by hydrochloric acid. (14) A thousand smells, of sausages and sweat, (18) Nitrate, Nitrite, Ammonia, Chloride, Orthophosphate, Total, (19) Immobilization of nitrogen occurs in both types in both sites but, (20) Case studies show that there is a reciprocal relationship between calcium and. On distillation with phosphorus sulphide it gives cymene. 230 sentence examples: 1. It contains, however, more nickel and also phosphorus. peak phosphorus in a sentence - Use "peak phosphorus" in a sentence 1. The triamide, PO(NH2)3, results from ammonia and phosphorus oxychloride. around Lexington is especially rich; outside of this area the Blue Grass soil is less rich in phosphorus and contains a larger mixture of sand. But not only is the combining power or valency (atomicity) of the elements different, it is also observed that one element may combine with another in several proportions, or that its valency may vary; for example, phosphorus forms two chlorides represented by the formulae PC1 3 and PC1 51 nitrogen the series of oxides represented by the formulae N 2 0, NO, (N203), N 2 O 4, N205, molybdenum forms the chlorides MoC1 2, MoC1 3, MoC1 4, MoC1 5, MoCls(? When heated with hydriodic acid and phosphorus to 200° C. it yields a hexahydride. In soils containing little phosphorus, plants with mycorrhizae have been shown to grow up to 20 times faster than those without. ), forming a deep red vapour, which exerts an irritating and directly poisonous action on the respiratory organs. The important reducing agents include hydrogen, hydrides such as those of iodine, sulphur, phosphorus, &c., carbon, many metals, potassium, sodium, aluminium, magnesium, &c., salts of lower oxyacids, lower salts of metals and lower oxides. It may be conveniently prepared by passing a rapid current of air over burning phosphorus contained in a combustion tube, and condensing the product in a metal condenser, from which it may be removed by heating the condenser to 50 0 -60° (Thorpe and Tutton, Jour. Bernthsen); by the action of ammonium chloride or hydrochlorides of amines on nitriles; by condensing amines and amides in presence of phosphorus trichloride; by the action of hydrochloric acid on acid-amides (0. It is reduced by sodium amalgam to benzhydrol or diphenyl carbinol C 6 H 5 [[Choh C 6 H]] 5; a stronger reducing agent, such as hydriodic acid in the presence of amorphous phosphorus converts it into diphenylmethane (C6H5)2. Phosphorus is obtained as a soluble phosphate (which can be examined in the usual way) by lixiviating the product obtained when the substance is ignited with potassium nitrate and carbonate. The anhydrous nitrate, obtained by heating the crystallized salt, is very phosphorescent, and constitutes "Baldwin's phosphorus.". orthorhombic black phosphorus is shown below. The sky skipped like chips of phosphorus in a bowl of water and oil seeped through cracked earth to the watertable: 10. Stock (Ber., 1909, 42, 4510), who points out that ordinary red phosphorus melts at 605°-610°, whilst Hittorf's melts at 620°; moreover, the latter is less reactive than the former at high temperatures. Examples of phosphorus in a sentence: 1. Red-phosphorus sentence examples When heated to 250° C. with red phosphorus and hydriodic acid it gives a hydride It is nitrated by nitric acid and sulphonated by sulphuric acid. He also investigated the oxygen compounds of phosphorus and nitrogen, and was ' The names of the musical instruments in those verses of the Book of Daniel have formed the basis of a controversy as to the authenticity of the book. Beside this their chief and easy work of oxidizing carbon, silicon and phosphorus, the conversion processes have the harder task of removing sulphur, chiefly by converting it into calcium sulphide, CaS, or manganous sulphide, MnS, which rise to the top of the molten metal and there enter the overlying slag, from which the sulphur may escape by oxidizing to the gaseous compound, sulphurous acid, S02. The parameter includes all forms of phosphorus ie total phosphorus. Phosphoric oxide, or phosphorus pentoxide, P4010, formed when phosphorus is burned in an excess of air or oxygen, or from dry phosphorus and oxygen at atmospheric pressure (Jungfleisch, loc.
