Nitrogen gaws mass

Nitrogen la xidhiidha group 15 (soocidda hore - in koox hoosaadka ugu weyn ee kooxda shanaad) ee muddada 2-dii at 7 tirada qaaradda ee System wakhtiyeysan ee Arimaha, iyo sida calaamad oo la nitrogen N. gaws mass waa 14 kg / mol.

Nitrogen sida walax fudud xaaladaha caadiga ah waa gaas dihydric inert aan lahayn midab lahayn, dhadhan lahayn, urta lahayn. gaaska Tani waxay qayb ka kooban yahay dhulka jawi. Miisaanka uu leeyahay kelli of nitrogen waa loo siman yahay si 28. Ereyga "nitrogen" Giriigga macnaheedu yahay "Noolayn".

In dabiiciga ah, u taagoo gaaska ka kooban yihiin isotopes deggan, taas oo mass ka gaws of nitrogen waa 14kg / mol (99.635%) iyo 15 kg / mol (0.365%). Ka baxsan jawi dhulka ee waxaa la helay in kooban of Nebulae gaseous, in jawiga qoraxda, meel interstellar on meerayaasha Neptune, Uranus, iyo wixii la mid ah. Waa afaraad ee nidaamka qoraxda si ay u faafiyaan ka dib markii xubno ka ah sida hydrogen, helium, ogsijiin. Kiimikaysan soo saaray isotopes shucaaca, taas oo mass ka gaws of nitrogen - laga bilaabo 10 kg / mol iyo ilaa 13kg / mol, iyo 16 kg / mol ilaa 25 kg / mol. Kulligood waxay ka tirsan tahay waxyaalaha-gaaban. The ugu xasiloon isotopes taas oo mass ka gaws of nitrogen waa 13kg / mol, waxay leedahay toban daqiiqo qeybtii nolosha.

Doorka noolaha ee gaaska this waa weyn, sababtoo ah waa mid ka mid ah waxyaabaha asaasiga ah oo ka kaas oo acids nucleic waxaa lagu daray, borotiinada, nucleoproteins, chlorophyll, hemoglobin, iyo waxyaabaha kale ee muhiimka ah. Labada isotope xasiloon oo nitrogen, iyo mass ka gaws waa 14kg / mol iyo 15 kg / bar ku lug-shiid nitrogen. Sababtan awgeed, aad u weyn nitrogen go'an jira noolaha, "ku dhintay" organic iyo particulate arrinta oo ka mid ah badaha iyo badaha. Oo weliba, iyada oo sababtu tahay hababka kala daatay iyo putrefaction ah, lacag dhigaal ah organic nitrogen-ka kooban nitrogen-ka kooban organic loo sameeyay sida, tus, amooniyam.

Nitrogen ka jawiga ay awoodaan in ay ku xidhaan oo u celi qaab digestible, tusaale ahaan, xeryahooda ammonium, oo ku saabsan 160 nooc oo sheyga, inta badan ka kooban in xiriir siman oo leh dhirta sare, kuwaas oo la siinayo bacrimin nitrogen, oo dheeraad ah oo ay la socdaan silsiladda cuntada helo in geedo daaq iyo carnivores.

Under xaaladaha shaybaarka, nitrogen waa la helay by ficil daatay nitrite ammonium. Natiijadu waxay tahay isku dar ah gaaska la ammonia, ogsijiin iyo xabagta nitrogen (I). Its nadiifiskeeda u soo saaray maraya ey isku keentay iyada oo xal acid koowaad sulfuric, ka dibna sulfate birta (II), ka dibna ka badan copper kulul. Hab kale oo ay u hesho shaybaarka ka kooban yahay maraya ee xabagta copper ammonia (II), heerkulka ah oo ku saabsan 700 degrees Celsius.

In qiyaasta warshadaha nitrogen helay maraya hawada ka badan coke kulul, laakiin ma sheyga saafi ah sameeyay, iyo mar kale isku dar ah, laakiin la gaasas sharaf iyo carbon dioxide, a ee loo yaqaan "hawada" ama "regenerative" gaaska. Waa qalab dihin oo Avv kiimikada iyo shidaalka. Sidoo kale, ka "matoor" gaaska nitrogen la soo kabsaday laga yaabaa, waayo nuugista waxaa loo sameeyay carbon monoxide. Habka labaad ee soo saara nitrogen in industry ee - muxaadaro jajab hawada oo dareere ah.

Sidoo kale waxaa jira farsamooyin sida xuub-soociddiisa gaaska iyo adsorption. Reception of nitrogen qaaradda, waxay wax badan oo firfircoon ka badan kelli, oo awood u leh, tusaale ahaan, in fal ku hoos jira xaalad caadi ah fosfooraska, baaruud, arsenic, biraha. xeryahooda nitrogen hubkaas ayaa loo isticmaalaa in industry ee ay qabanayaan Bacriminta, waxyaabaha qarxa, daawooyinka, formaldehyde iyo wixii la mid ah. In warshadaha kiimikada waxaa la nadiifiyey khadadka, hubi shaqadooda cadaadis. In adag macdanta ay gargaar ka abuuraan gudahood deegaanka qarax-caddeynta anigaa iska leh, inay Cadha daraadeed iyaga rock qaababka. In korontada ay Suurka kiniisadood, taas oo aan waxba ka jirin lagu qayilo yar by oxygen ku jira hawada.
