Synthesis thiab reactivity
Tom qab thawj zaug sim cov synthesis hauv 1903, Otto Ruff tau npaj nitrogen trifluoride los ntawm electrolysis ntawm ib tug molten sib tov ntawm ammonium fluoride thiab hydrogen fluoride.
Ntxiv rau qhov no, nitrogen trifluoride ua li cas?
NF3 Ntau Lawm los ntawm Electrolysis hauv Molten Fluorides Piv txwv li, nitrogen trifluoride (NF3) yog cov pa ruaj khov ntawm chav tsev kub thiab muaj zog oxidation zog ntawm qhov kub siab dua [3-5]. Txog li 200 ° C, nws cov reactivity piv rau oxygen. Tshaj 400 ° C, lub reactivity ntawm NF3 ua zoo li fluorine.
Ib tug kuj yuav nug, hom ntawv cog lus twg yog nitrogen trifluoride? Lub molecule muaj ib tug trigonal pyramidal qauv, zoo li ammonia. Cov daim ntawv cog lus lub kaum sab xis yog txo los ntawm 107 ° hauv ammonia rau 101.9 ° hauv NF3, vim tias cov fluorine electronegative heev rub cov electrons hauv N-F daim ntawv cog lus ntawm lawv tus kheej, txo qis interelectronic repulsions, kom NF3 'umbrella' kaw.
Ntxiv mus, dab tsi yog cov tshuaj formula rau nitrogen trifluoride?
NF3
Puas yog nf3 yog oxidizer?
Nitrogen Trifluoride ( NF3 ) yog kev txaus siab raws li ib tug oxidizer ntawm cov roj hluav taws xob siab, rau kev npaj ntawm tetrafluorohydrazine, thiab rau fluorination ntawm fluorocarbon olefins. Ib qho tsis muaj xim, tsis muaj hluav taws xob, cov roj liquefied nrog cov ntxhiab tsw. Muaj tshuaj lom; Irritates cov huab cua. Ib tug muaj zog oxidizer.

Vim li cas nitrogen tsev neeg hu ua Pnictogens?
Kuj Paub Raws Li: Cov ntsiab lus ntawm pawg no tseem hu ua pnictogens, ntawm lub sij hawm muab los ntawm Greek lo lus pnigein, uas txhais tau hais tias 'kom choke'. Qhov no yog hais txog cov khoom choking ntawm cov pa nitrogen (tsis yog cua, uas muaj cov pa oxygen thiab nitrogen)
Nitrogen teb li cas nrog hydrogen?
Nitrogen gas (N 2) reacts nrog hydrogen gas (H 2) tsim ammonia gas (NH 3). Koj muaj nitrogen thiab hydrogen gases nyob rau hauv 15.0-L thawv haum nrog lub piston txav tau (lub piston tso cai rau lub ntim ntim hloov thiaj li ua kom lub siab tsis tu ncua hauv lub thawv)
Lub mole ntawm diatomic nitrogen n2 hnyav npaum li cas?
1 mole yog sib npaug rau 1 moles N2, los yog 28.0134 grams
Yuav ua li cas thaum nitrogen rhuab nrog hydrogen?
Thaum nitrogen reacts nrog hydrogen nyob rau hauv kub thiab siab, ammonia, uas kuj yog ib tug gas yog tsim
Cov pa roj carbon thiab nitrogen cycles txuas li cas?
Kev ua kom sov hauv ntiaj teb no yog qhov tshwm sim ntawm cov pa roj carbon dioxide ntau ntxiv thiab lwm lub tsev cog khoom hauv huab cua. Lub voj voog nitrogen pib nrog cov pa nitrogen hauv cov huab cua ces dhau los ntawm nitrogen-kho cov kab mob mus rau cov nroj tsuag, tsiaj txhu, decomposers, thiab mus rau hauv av
