Qhov sib txawv tseem ceeb ntawm NF3 thiab NH3 yog tias NF3 muaj peb lub fluorine atoms khi rau lub hauv paus nitrogen atom, thaum NH3 muaj peb hydrogen atoms khi rau lub hauv paus nitrogen atom.
NF3 yog nitrogen trifluoride thaum NH3 yog ammonia. Ob leeg yog inorganic compounds, thiab ob lub tebchaw muaj tib lub molecular geometry. Txawm li cas los xij, lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv vim muaj cov atomic sib txawv.
NF3 yog dab tsi?
NF3 yog nitrogen trifluoride. Nws lub npe yog trifluoramine. Nws muaj peb lub fluorine atoms khi rau tib lub nitrogen atom ntawm covalent tshuaj bonding. Txij li thaum nitrogen muaj tsib valence electrons thiab peb fluorine atoms siv tsuas yog peb ntawm cov electrons los ua tshuaj bonds, muaj ib leeg electron khub ntawm lub nitrogen atom. Cov khub electron thiab peb covalent bonds ua rau NF3 molecule kom muaj trigonal pyramidal geometry. Tus qauv yog raws li nram no:
Daim duab 01: Cov qauv ntawm Nitrogen Trifluoride
Cov molar loj ntawm nitrogen trifluoride yog 71 g / mol. Nws zoo nkaus li tsis muaj xim tsis muaj roj, thiab nws muaj ntxhiab tsw ntxhiab. Tsis tas li ntawd, nws yog ib qho tsis-flammable gas. Txawm li cas los xij, cov pa roj no yog lub tsev cog khoom muaj zog. Thaum muaj hluav taws xob tawm, peb tuaj yeem npaj qhov sib xyaw no siv nws cov tshuaj lom neeg; Yog li, nws yog qhov tsis tshua muaj qhov sib xyaw uas peb tuaj yeem npaj ncaj qha siv nws cov tshuaj (nitrogen thiab fluorine atoms).
Dhau li ntawm, qhov sib xyaw no qhia txog kev solubility hauv dej. Tsis tas li ntawd, nitrogen trifluoride tsis yog qhov tseem ceeb, thiab nws muaj lub sijhawm tsis tshua muaj dipole vim tias cov fluorine atoms ua raws li pawg electron rho tawm; Yog li, lawv tuaj yeem nyiam ib leeg electron khub ntawm nitrogen atom. Tsis tas li ntawd, qhov sib xyaw no yog lub zog oxidizer zoo li. Thaum xav txog kev siv cov tshuaj no, nws muaj txiaj ntsig zoo hauv plasma etching ntawm silicon wafers hauv cov ntawv thov electrochemical.
NH3 yog dab tsi?
NH3 yog ammonia. Nws muaj peb hydrogen atoms khi rau tib lub nitrogen atom. Zoo li nitrogen trifluoride, qhov sib xyaw no kuj muaj ib khub electron. Nws yog binary halide. Tsis tas li ntawd, qhov sib xyaw no tshwm sim raws li cov pa tsis muaj xim, thiab nws muaj pungent, irritating tsw. Lub geometry ntawm no compound yog trigonal pyramidal.
Daim duab 02: Cov qauv ntawm Ammonia Molecule
Cov molar loj ntawm ammonia yog 17 g / mol. Hauv qhov xwm txheej, peb tuaj yeem pom cov pa roj no ua cov kab sib txuas tsim los ntawm nitrogenous pov tseg thiab nitrogenous tsiaj thiab nroj tsuag teeb meem. Thaum xav txog nws cov kev siv, kwv yees li 88% ntawm ammonia yog siv rau kev tsim cov chiv. Nws kuj tseem siv tau los ua ib qho precursor rau nitrogenous tebchaw. Hauv cov txheej txheem fermentation, ammonia muaj txiaj ntsig zoo li nitrogen qhov chaw rau cov kab mob. Aqueous ammonia kuj tseem ceeb raws li kev siv tshuaj ntxuav hauv tsev.
Dab tsi zoo sib xws ntawm NF3 thiab NH3?
- NF3 thiab NH3 yog binary compounds.
- Lawv muaj tib lub geometry - trigonal pyramidal
- Ntxiv mus, ob qho tib si tshwm sim ua tsis muaj xim tsis muaj roj
- Ntxiv rau qhov no, ob lub molecules muaj ib leeg electron khub ntawm nitrogen atoms.
Qhov txawv ntawm NF3 thiab NH3 yog dab tsi?
NF3 yog nitrogen trifluoride thaum NH3 yog ammonia. Qhov sib txawv tseem ceeb ntawm NF3 thiab NH3 yog tias NF3 muaj peb lub fluorine atoms khi rau lub hauv paus nitrogen atom, thaum NH3 muaj peb hydrogen atoms khi rau lub hauv paus nitrogen atom. Cov molar loj ntawm nitrogen trifluoride yog 71 g / mol thaum molar loj ntawm ammonia nws yog 17 g / mol. Ntxiv mus, NF3 yog nonbasic thaum NH3 yog ib qho yooj yim compound; NF3 muaj lub sijhawm dipole tsawg, tab sis NH3 muaj lub sijhawm dipole siab. NF3 yog qhov tseem ceeb hauv plasma etching ntawm silicon wafers hauv kev siv electrochemical. Nyob rau hauv sib piv, NH3 yog pab tau rau chiv ntau lawm, rau fermentation raws li lub nitrogen qhov chaw, raws li ib tug huv tsev neeg daim ntaub ntawv, thiab lwm yam.
Cov duab hauv qab no qhia txog qhov sib txawv ntawm NF3 thiab NH3.
Summary – NF3 vs NH3
NF3 yog nitrogen trifluoride thaum NH3 yog ammonia. Ob leeg yog inorganic compounds. Qhov sib txawv tseem ceeb ntawm NF3 thiab NH3 yog tias NF3 muaj peb lub fluorine atoms khi rau lub hauv paus nitrogen atom, thaum NH3 muaj peb hydrogen atoms khi rau lub hauv paus nitrogen atom.
