I-nitrogen (N2)

Iiparamitha zobugcisa

I-Nitrojeni (N2) yenza eyona nxalenye ingundoqo yeatmosfera yomhlaba, ibalelwa kuma-78.08% ewonke. Yigesi engenambala, ayinavumba, ayinancasa, ayinatyhefu kwaye iphantse ibe yigesi engasebenziyo ngokupheleleyo. I-nitrojeni ayinakutsha kwaye ithathwa njengegesi efunxayo (oko kukuthi, ukuphefumla i-nitrogen ecocekileyo kuya kuhlutha umzimba womntu oksijini). I-nitrogen ayisebenzi kwiikhemikhali. Iyakwazi ukusabela nge-hydrogen ukwenza i-ammonia phantsi kobushushu obuphezulu, uxinzelelo oluphezulu kunye neemeko ze-catalyst; inokudibanisa neoksijini ukwenza i-nitric oxide phantsi kweemeko zokukhutshwa. I-nitrogen idla ngokubizwa ngokuba yigesi engasebenziyo. Isetyenziswe kwi-atmospheres ye-inert ethile yonyango lwetsimbi kunye nakwii-bulbs ukukhusela i-arcing, kodwa ayiyi-inert ye-chemically. Yinto ebalulekileyo kubomi bezityalo nezilwanyana, kwaye iyinxalenye yezinto ezininzi eziluncedo. I-nitrojeni idityaniswa neentsimbi ezininzi ukwenza i-nitrides eqinile, enokusetyenziswa njengeentsimbi ezingagugiyo. Inani elincinci le-nitrogen kwintsimbi liya kuthintela ukukhula kweenkozo kumaqondo okushisa aphezulu kwaye liya kwandisa amandla eentsimbi ezithile. Ingasetyenziselwa ukuvelisa iindawo ezinzima kwintsimbi. I-nitrogen ingasetyenziselwa ukwenza i-ammonia, i-nitric acid, i-nitrate, i-cyanide, njl. ekwenzeni iziqhushumbisi; ukuzalisa iithemomitha zobushushu obuphezulu, iibhalbhu ze-incandescent; ukwenza izinto ze-inert zokugcina izinto, ezisetyenziselwa kwiibhokisi zokumisa okanye iingxowa zeglavu. Ulwelo lwenitrogen ngexesha lokukhenkceza kokutya; isetyenziswe njengesipholisi kwilabhoratri. I-nitrogen kufuneka igcinwe nkqo kwindawo engenamoya, ekhuselekileyo nengenamozulu, kwaye ubushushu bokugcina akufunekanga bube ngaphezulu kwe 52°C. Akufunekanga kubekho izinto ezinokutsha kwindawo yokugcina kwaye ugcine kude kwiindawo zokungena nokuphuma rhoqo kunye neendawo zokuphuma ngokukhawuleza, kwaye kungabikho tyuwa okanye ezinye izinto ezidliwayo. Kwiisilinda zegesi ezingasetyenziswanga, i-valve cap kunye ne-valve yokuphuma kufuneka ivalwe kakuhle, kwaye iisilinda ezingenanto kufuneka zigcinwe ngokwahlukileyo kwiisilinda ezipheleleyo. Gwema ukugcinwa ngokugqithiseleyo kunye nexesha elide lokugcina, kwaye ugcine iirekhodi ezilungileyo zokugcina.

Isicelo:
