Qhov sib txawv tseem ceeb ntawm rhombic thiab monoclinic sulfur yog tias rhombic sulfur yog qhov ruaj khov tshaj plaws allotropic daim ntawv ntawm leej faj uas muaj xws li rhombic octahedral crystals whereas monoclinic sulfur muaj nyob ntev, koob-puab prisms tab sis, nws yog ruaj khov xwb. ntawm qhov kub ntawm 96◦C thiab 119◦C.
Sulphur, kuj sau nws li "sulfur", yog cov khoom siv tshuaj lom neeg muaj cov cim tshuaj S thiab atomic naj npawb 16. Nws yog nonmetal thiab tshwm sim nyob rau hauv cov xwm txheej nyob rau hauv ntau hom allotropic. Tsis tas li ntawd, nyob rau hauv chav tsev kub, nws yog yooj yim muaj raws li ci daj xim muaju. Qhov loj ntawm Sulfur muaj xws li cov pa roj carbon monoxide, rho tawm hauv qab lub ntiaj teb crust thiab raws li cov khoom lag luam ntawm lwm cov txheej txheem tshuaj. Rhombic thiab monoclinic Sulfur yog ob hom allotropic; allotropes yog cov ntaub ntawv sib txawv ntawm tib cov tshuaj lom neeg uas muaj nyob hauv tib lub cev lub cev, piv txwv li kev hloov kho cov qauv. Tsis tsuas yog cov qauv tab sis kuj yog txoj kev npaj ntawm cov allotropes kuj txawv ntawm ib leeg.
Rhombic Sulphur yog dab tsi?
Rhombic Sulphur, lossis alpha-Sulphur, yog crystalline allotropic daim ntawv ntawm Sulfur uas muaj rhombic octahedral crystals. Nws yog daim ntawv ruaj khov tshaj plaws ntawm allotrope ntawm lwm cov allotropes ntawm Sulphur. Yog li ntawd, yuav luag tag nrho lwm cov allotropes nws thiaj li hloov mus rau hauv daim ntawv rhombic.
Daim duab 01: Crystals ntawm Rhombi Sulphur
Thaum xav txog txoj kev npaj, ua ntej peb yuav tsum yaj cov hmoov sulfur hauv carbon disulphide (ntawm chav tsev kub); nws yog insoluble hauv dej. Tom qab ntawd peb tuaj yeem lim cov sib tov siv cov ntawv lim. Tom qab kev pom, peb yuav tsum khaws cov filtrate nyob rau hauv lub beaker, npog nrog ib daim ntawv lim. Qhov no tso cai rau cov carbon disulphide evaporate maj mam, tawm hauv alpha sulfur crystals. Qhov ceev ntawm cov crystals yog nyob ib ncig ntawm 2.06 g / mL, thiab lub melting point ntawm 112.8◦C. Yog tias peb sov rhombic sulfur mus txog 96◦C maj mam, nws hloov mus rau hauv daim ntawv monoclinic.
Monoclinic Sulphur yog dab tsi?
Monoclinic sulfur yog crystalline allotropic daim ntawv ntawm leej faj uas muaj koob zoo li, ntev muaju. Cov crystals zoo li prisms; yog li peb tuaj yeem hu cov crystals li prismatic sulfur. Nws tsis ruaj khov npaum li rhombic sulphur, yog li ntawd, nws hloov mus rau hauv daim ntawv rhombic thaum rhuab mus txog 94.5◦C maj mam. Daim ntawv monoclinic ruaj khov tshaj 96◦C.
Daim duab 02: Monoclinic Sulfur Crystals
Qhov ntom ntawm daim ntawv allotropic no yog kwv yees li 1.98 g / mL, thiab qhov melting point yog 119◦C. Thaum kub qis dua 96◦C, nws hloov mus rau hauv daim ntawv rhombic. Thaum xav txog cov txheej txheem ntawm kev npaj ntawm daim ntawv no, ua ntej peb yuav tsum sov sulfur hmoov rau ntawm ib lub tais evaporating, kom txog rau thaum cov hmoov sulfur melts. Tom qab ntawd peb yuav tsum cia nws txias kom txog thaum muaj cov khoom crusts saum npoo. Tom qab tsim cov crust no, peb yuav tsum ua ob qhov ntawm lub crust thiab ncuav tawm cov molten sulfur tawm ntawm nws. Nyob rau sab qis ntawm lub pob zeb, peb tuaj yeem pom monoclinic sulfur crystals.
Qhov txawv ntawm Rhombic thiab Monoclinic Sulphur yog dab tsi?
Rhombic Sulfur yog ib daim ntawv crystalline allotropic ntawm Sulfur uas muaj rhombic octahedral crystals. Nws yog daim ntawv ruaj khov tshaj plaws ntawm allotrope ntawm lwm cov ntaub ntawv allotropic ntawm sulfur. Yog li ntawd, lwm cov allotropes kuj nyiam hloov mus rau hauv daim ntawv rhombic. Monoclinic sulfur yog crystalline allotropic daim ntawv ntawm leej faj uas muaj koob zoo li, ntev muaju. Nws ruaj khov ntawm qhov kub ntawm 96◦C thiab 119◦C. Qhov no yog qhov sib txawv tseem ceeb ntawm rhombic thiab monoclinic sulfur. Ntxiv rau qhov sib txawv ntawm cov qauv ntawm rhombic thiab monoclinic sulfur, lawv kuj txawv me ntsis hauv qee cov khoom raws li hauv txoj kev npaj.
Summary – Rhombic vs Monoclinic Sulphur
Sulphur yog ib yam khoom tsis muaj sia uas muaj ntau hom allotropic uas muaj nyob hauv tib lub cev. Rhombic daim ntawv thiab monoclinic daim ntawv yog xws li ob allotropes. Qhov sib txawv ntawm rhombic thiab monoclinic sulfur yog tias rhombic sulfur muaj xws li rhombic octahedral crystals whereas monoclinic sulfur muaj nyob ntev, koob-puab prisms.
