Sulfur hexafluoride thiab disulfur tetrafluoride yog cov tshuaj inorganic. Ob leeg muaj sulfur thiab fluorine atoms nyob rau hauv sib txawv kev sib txuas thiab spatial kev npaj. Txawm li cas los xij, tsis yog lawv cov qauv tshuaj xwb tab sis lub cev lub cev thiab lwm yam khoom ntawm ob lub tebchaw no kuj txawv ntawm ib leeg. Piv txwv li, sulfur hexafluoride yog ib qho chaw gaseous ntawm chav tsev kub, tab sis disulfur tetrafluoride yog cov kua.
Sulfur Hexafluoride yog dab tsi?
Sulfur hexafluoride yog ib qho inorganic compound uas muaj cov tshuaj formula SF 6Nws yog ib qho tsis muaj xim thiab tsis muaj ntxhiab tsw ntxhiab uas tsis yog nplaim taws thiab tsis muaj tshuaj lom. Nws yog categorized li lub tsev xog paj. Nws kuj yog ib qho tseem ceeb hluav taws xob insulator. Nws yog ib qho roj uas denser tshaj huab cua.
Lub geometry ntawm qhov chaw no yog octahedral. Daim ntawv cog lus ntev ntawm tag nrho cov S-F daim ntawv cog lus nyob rau hauv no molecule yog sib npaug. Sulfur hexafluoride muaj lub hauv paus sulfur atom txuas rau rau fluorine atoms. Tsis tas li ntawd, cov molecule no suav hais tias yog ib qho hypervalent molecule. Qhov ntawd txhais tau tias; cov molecule no muaj ib pab pawg tseem ceeb uas muaj ntau tshaj yim valence electrons. Nyob rau hauv no molecule, cov sulfur atom muaj kaum ob electrons.
Vim yog kev sib txuas ntawm cov atoms thiab lawv qhov chaw nyob, cov sulfur hexafluoride molecule yog nonpolar thiab yog insoluble hauv dej. Tab sis, nws yog soluble nyob rau hauv nonpolar organic solvents. Peb tuaj yeem tsim cov khoom sib xyaw no siv cov khoom siv ntshiab sulfur thiab fluorine. Ntawm no peb yuav tsum nthuav tawm S8 khoom rau F2 gas.
Muaj ntau daim ntawv thov ntawm sulfur hexafluoride:
- Siv ua hluav taws xob hluav taws xob hluav taws xob kev lag luam
- Nyob rau hauv tshuaj los muab cov tamponade hauv retinal detachments
- Raws li tus neeg sawv cev sib txawv hauv kev kuaj pom ultrasound,
- Raws li cov pa roj hauv kev ntsuas txoj kev huab cua dispersion qauv, thiab lwm yam.
Disulfur Tetrafluoride yog dab tsi?
Disulfur tetrafluoride yog ib qho inorganic compound uas muaj cov tshuaj formula S2F4 Ntau dua, peb tuaj yeem sau cov qauv qauv rau cov khoom sib xyaw no. raws li FSSF3 vim tias nws muaj peb lub fluorine atoms txuas rau ib qho sulfur atom thiab lwm cov sulfur atom muaj cov fluorine atom ntxiv. Daim ntawv cog lus ntev ntawm cov molecule no txawv, uas yog ib qho khoom tsis sib xws ntawm cov khoom siv tsis zoo.
Cov molar loj ntawm cov tshuaj no yog 140 g / mol. Nws muaj nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub. Tsis tas li ntawd, disulfur tetrafluoride yooj yim nkag mus rau hydrolysis nrog dej. Nws kuj spontaneously reacts nrog oxygen los tsim thionyl fluoride. Peb tuaj yeem npaj cov tshuaj disulfur tetrafluoride hauv chav kuaj siv cov tshuaj sulfur chloride uas dhau los ntawm potassium fluoride ntawm qhov tsis tshua muaj siab thiab tsis kub. Cov tshuaj tiv thaiv no, txawm li cas los xij, muab ntau cov khoom lag luam suav nrog ntau cov tshuaj chlorides thiab fluorides ntawm leej faj. Peb tuaj yeem cais qhov xav tau los ntawm qhov ntsuas kub qis.
Qhov txawv ntawm Sulfur Hexafluoride thiab Disulfur Tetrafluoride yog dab tsi?
Sulfur hexafluoride thiab disulfur tetrafluoride yog cov tshuaj inorganic uas muaj sulfur thiab fluorine atoms. Qhov sib txawv tseem ceeb ntawm sulfur hexafluoride thiab disulfur tetrafluoride yog cov sulfur hexafluoride muaj cov tshuaj sib npaug nrog cov nyiaj sib npaug, tab sis disulfur tetrafluoride muaj cov tshuaj sib txuas nrog cov ntawv sib txawv ntev. Tsis tas li ntawd, sulfur hexafluoride yog ib qho chaw gaseous ntawm chav tsev kub, tab sis disulfur tetrafluoride yog cov kua. Yog li, qhov no yog lwm qhov sib txawv tseem ceeb ntawm sulfur hexafluoride thiab disulfur tetrafluoride.
Ntxiv mus, molar pawg ntawm sulfur hexafluoride yog 146 g / mol, thaum molar loj ntawm disulfur tetrafluoride yog 140 g / mol. Tsis tas li ntawd, peb tuaj yeem tsim cov sulfur hexafluoride los ntawm kev siv cov tshuaj dawb huv thiab cov tshuaj fluorine thaum kev npaj ntawm disulfur tetrafluoride yuav tsum tau dhau cov sulfur chloride tshaj cov tshuaj fluoride ntawm qhov tsis tshua muaj siab thiab tsis kub thiab sib cais siv cov distillation qis.
Summary – Sulfur Hexafluoride vs Disulfur Tetrafluoride
Sulfur hexafluoride thiab disulfur tetrafluoride yog cov tshuaj inorganic uas muaj sulfur thiab fluorine atoms. Qhov sib txawv tseem ceeb ntawm sulfur hexafluoride thiab disulfur tetrafluoride yog cov sulfur hexafluoride muaj cov tshuaj sib npaug nrog cov nyiaj sib npaug, thaum disulfur tetrafluoride muaj cov tshuaj sib txuas nrog cov nyiaj sib txawv ntev.
