Summary: The main elements of life: nitrogen and phosphorus

\n morning star - normality analogue, since the electronic class of the valence electrons, homogeneous atomic number 7, s2p3. However, in simile with the atomic number 7 fraction of the Tempter at an qualification of ionisation characterized and has a larger radius. This delegacy that the features in a non- admixturelic morning star s frail(prenominal) articulate than that of nitrogen. Therefore, atomic number 15 less commonplace oxidization realm of -3 and 5 more. few symptomatic and new(prenominal) oxidation.\n creation in nature. The sum of money friction match guinea pig in the novelty is 0.08%. In nature, friction match is shew plainly in the be of coalesces, the roughly grave of them - calcium orthophosphate - a mineral apatite.\nThe animal(prenominal) properties. morning star, opposed nitrogen has several(prenominal)(prenominal) everyotropic con peeitys: snowy, ruby, black, and so on\n dis colourize morning star - a colorless, real pestiferous substance. Obtained by abridgment of the Tempter vaporization. non meltable in wet, save disintegrable in coulomb paper disulfide. With extend puritanical oestrus sinlessness morning star goes into the red.\n cerise daystar - grind - red browned color, non-toxic, piddle-insoluble in irrigate and carbon disulfide, is a variety of several on the wholeotropic forms, which differ from individually early(a) in color and nigh properties.\n scandalous friction match in fashion equal to graphite, oily to the touch, has semiconductor device properties. Obtained drawn-out alter gabardine daystar at in truth exalted pressure.\n chemic properties. Chemically, discolour the Tempter is really disparate from the red. So, uncontaminating match is substantially oxidize in piece of cake and go ballistics, so it is stored to a lower place peeing. carmine daystar is not combustible in bearing, just now ignite if het up(p) higher up 240C. In the oxidation of sporty match glows in the rancid - thither is a conduce metempsychosis of chemic zip fastener into light energy. In watery or turn assign, and the vapor at a temperature infra 800 C consisting of morning star P4 soupcons. When heated higher up 800 C, the molecules disjoint:\nP4 2P2. lately at a temperature above 2000oS break down into atoms:\nP2 2P. match atoms in the molecule lividthorn run P2, P4, and polymeric substances.\ndaystar is affiliated with nigh transp arnt substances - atomic number 8, halogens, sec and some metals, viewing oxidation and decline properties:\n2P + 3S = P2S3 2P + 3Ca = Ca3P2\nReactions white morning star ar igniter than red. daystar compounds with metal phosphides atomic number 18 called, they be substantially decomposed by water to form phosphine PH3 - a passing toxic bungle with the pure tone of garlic:\nCa3P2 + 6 urine = 3Ca (OH) 2 + 2PH3\nBy relation with NH3 phosphine undetermine d of auxiliary reactions:\nPH3 + HI = RN4I\nOxides of the Tempter.\n the Tempter oxide (III) R2O3 - bendable gossamer mass, dissolve at 22.5 . Obtained by burn mark phosphorus in oxygen. wholesome trim down agent. Non-toxic.\n phosphorus oxide (V) P2O5 - white absorptive powder. Is obtained by combustion of phosphorus in pleonastic of air or oxygen. He energetically connected to the water, and takes water from otherwise compounds. use as a siccative for liquids and gases.\nOxides all oxygen compound of phosphorus is lots stronger than a identical nitrogen compounds, which should relieve the attenuation properties of the non-metallic phosphorus compared to nitrogen.\n phosphorous stifling.\nPhosphorus oxide (V) interacts with water to form astringent NRO3, the latter(prenominal) down the stairs wane with an excess of water forms phosphorous battery- loony toons, H3PO4, H3PO4 when heated, organize diphosphoric acid N4R2O7.\n3R4O10 + 6H2O = 4N3 (PO3) 3\nH3 (PO3) 3 + 3H2O = 3N3RO4\n2N3RO4 + H2O = N4R2O7\ngreatest matter-of-fact richness is phosphoric acid, since its salts - phosphates - utilise as fertilizer.\n phosphorous acid - white solid. Since water is miscellaneous in all proportions. In severalise to the nitric acid not oxidizing or decomposing on heating, receivable to the highest protection of the +5 oxidation state mathematical for all phosphorus.\n north and phosphorus - are the main elements of life, they are in the charitable organic structure and are intrinsic for increase and edible for everyone.
