Zvivakwa zveNitrojeni: Maonero Akadzama eGasi Rakakosha Muindasitiri Yemakemikari
Seyakajairwa inert gasi muindasitiri yemakemikari, nitrogen inoshandiswa zvakanyanya mukugadzirwa kwakasiyana-siyana uye maitiro ekuyedza nekuda kwekusiyana kwayo kwemuviri nemakemikari zvimiro. Muchikamu chino, tichakurukura zvimiro zve nitrogen zvakadzama kuti tikubatsire kunzwisisa zviri nani kukosha kwegasi iri muindasitiri.
I. Basic Physical Properties yeNitrogen
Nitrogen (N₂) igasi risina ruvara, risinganhuhwi uye risiri muchetura patembiricha yepakamuri nekumanikidzwa. Huremu hwayo ndeye 28.0134 g/mol uye density i1.2506 kg/m³, inoreruka zvishoma pane mweya. Mukugadzirwa kwemakemikari, nitrogen inowanzo shandiswa kugadzira nharaunda dzine tembiricha yakaderera nekuda kwekudzika kwayo kuvira (-195.8°C), uye mvura nitrogen inowanzo shandiswa sechinhu chinotonhodza. Iyo yakaderera solubility uye yakaderera magetsi conductivity yenitrogen inoita kuti ibatsire zvakanyanya mune dzimwe nzvimbo dzakakosha.
Chechipiri, iyo makemikari inertness yenitrogen
Imwe yeakakosha maitiro enitrogen ikemikari inertness. Pamatembiricha akajairwa uye kumanikidzwa, iyo nitrogen molecule (N₂) yakagadzikana nekuti ine maviri maatomu enitrogen akabatana nekatatu bond, izvo zvinoita kuti isashande mukuita kwakawanda kwemakemikari. Ichi chemikemikari inertness inobatsira mune dzakawanda maindasitiri ekushandisa, semuenzaniso, kana ichishandiswa mukupisa, kuchengetedza chikafu uye segasi rinodzivirira mukuitika kwemakemikari, nitrogen inodzivirira kudzivirira oxidation, kupisa uye mamwe maitiro asingadiwe emakemikari.
III. Kuchengetedzeka uye kukanganisa kwezvakatipoteredza kwenitrogen
Kunyangwe nitrogen inoshandiswa zvakanyanya muindasitiri yemakemikari, kuchengetedzwa kwayo kuchiri nyaya yakakosha. Kunyange zvazvo nitrogen pachayo isiri chepfu, kubuda kwehuwandu hwenitrogen munzvimbo yakavharirwa kunogona kukonzera kudzikiswa kweokisijeni, izvo zvinozoita kuti pave nengozi yekufemerwa. Saka zvakakosha kuve nechokwadi chekufefetera kwakanaka uye maitiro akasimba ekuchengetedza kana uchishandisa nitrogen. Sezvo nitrogen isingaiti pamwe nezvimwe zvikamu mumhepo, haina ngozi kune zvakatipoteredza uye haitungamiri kune greenhouse effect kana kuparadza ozone layer.
IV. Indasitiri Kushandiswa kweNitrogen
Nitrogen ine huwandu hwakawanda hwekushandisa muindasitiri yemakemikari nekuda kweiyo yakasarudzika midziyo. Semuenzaniso, mukugadzirisa kwemakemikari, nitrogen inowanzoshandiswa seinert gasi kudzivirira oxidation kana hydrolysis ye reactants; muindasitiri yezvekudya, nitrogen inoshandiswa kurongedza uye kuchengetedza kuwedzera hupenyu hwesherufu yechikafu; mukugadzirwa kwemagetsi, nitrogen inoshandiswa kuchengetedza zvinhu zvemagetsi zvine hunyoro kubva kunyoro kana oxidation.
Summary
Nekuongorora maitiro enitrogen zvakadzama, tinogona kuona kuti nitrogen igasi rakakosha uye rakakosha muindasitiri yemakemikari nekuda kwekugadzikana kwayo kwemuviri uye kusagadzikana kwemakemikari. Kunzwisisa uye kugona zvimiro zve nitrogen hazvingobatsiri kushanda kwakachengeteka, asi zvakare kunovandudza kugadzirwa kwemaindasitiri. Mune ramangwana rekuvandudza tekinoroji, mukana wekushandisa wenitrogen ucharamba uchiwedzera, uchipa mamwe mhinduro kumaindasitiri akasiyana.
