iron sulfide ezimbili

I-Iron Two Sulfide: Umhlahlandlela OpheleleI-Iron two sulfide, eyaziwa nangokuthi i-ferrous sulfide, iyinhlanganisela yamakhemikhali enefomula i-FeS. Lo mhlahlandlela unikeza umbono obanzi wezakhiwo zawo, ukuhlanganiswa, izinhlelo zokusebenza, nokucatshangelwa kokuphepha.

Izakhiwo ze-Iron Two Sulfidi

Iron sulfide ezimbili ikhona ngezinhlobo eziningana zekristalu, evame kakhulu i-mineral pyrrhotite eyenzeka ngokwemvelo. Le mineral ivame ukubonisa ukwakheka okungeyona i-stoichiometric, okusho ukuthi isilinganiso sensimbi nesulfure singahluka kancane. Okumsulwa iron sulfide ezimbili inombala ompunga okumnyama kuye komnyama. Ayincibiliki emanzini kodwa ihlangana nama-asidi ukuze ikhiqize igesi ye-hydrogen sulfide, into enobuthi obuphezulu futhi evuthayo. Iphuzu layo lokuncibilika liphakeme kakhulu, cishe ku-1195 °C (2183 °F).

Izakhiwo Zomzimba

| Impahla | Inani ||-----------------|--------------------------------------|| Chemical Formula | I-FeS | I-Molar Mass | 87.91 g/mol || Ukuminyana | 4.7–5.0 g/cm3 || Melting Point | 1195 °C (2183 °F) || Ukubukeka | Okumpunga okumnyama kuye komnyama okuqinile |

Chemical Properties

Iron sulfide ezimbili isabela kalula nama-asidi, njenge-hydrochloric acid (HCl), ukukhiqiza igesi ye-hydrogen sulfide (H?S):FeS(s) + 2HCl(aq) → FeCl?(aq) + H?S(g)Lokhu kusabela kuvame ukusetshenziswa lapho kulungiswa ilabhorethri ye-hydrogen sulfide. Ukusabela nge-oxygen nakho kungase kwenzeke, okuholela ekwakhekeni kwe-iron oxides kanye ne-sulfur dioxide.

Ukuhlanganiswa kwe-Iron Two Sulfide

Iron sulfide ezimbili ingahlanganiswa ngezindlela eziningi. Indlela evamile ihilela ukusabela ngokuqondile kwe-iron nesulfure emazingeni okushisa aphakeme:I-Fe(izi) + S(s) → I-FeS(ama)Lokhu kusabela kuyingozi kakhulu futhi kudinga ukulawula ngokucophelela ukuvimbela ukushisa okungalawuleki. Enye indlela ihilela ukusabela kwezulu phakathi kwensimbi encibilikayo(II) usawoti kanye nosawoti we-sulfide oncibilikayo:FeCl?(aq) + Na?S(aq) → FeS(s) + 2NaCl(aq)Le ndlela ikhiqiza imvula iron sulfide ezimbili ezingase zihlungwe futhi zomiswe.

Izicelo ze-Iron Two Sulfidi

Iron sulfide ezimbili ithola izinhlelo zokusebenza ezimbonini ezahlukahlukene. Isicelo esisodwa esibalulekile siwukukhiqizwa kwegesi ye-hydrogen sulfide, esetshenziswa ezinqubweni ezihlukahlukene zezimboni nanjengento evuselelayo ekuhlanganiseni kwamakhemikhali. Iphinde ibambe iqhaza ekusetshenzisweni kwensimbi nensimbi, isebenze njengomthombo wesibabule. Ngaphezu kwalokho, iyingxenye kwezinye izingulube. Nokho, ngenxa yobuthi bamagesi engase iwukhiqize, ukusetshenziswa kwawo kudinga izinyathelo zokuphepha ezibalulekile.

Ukucatshangelwa Kokuphepha

Kubalulekile ukuphatha iron sulfide ezimbili ngokunakekela ngenxa yamandla ayo okusabela nama-asidi ukukhiqiza igesi ye-hydrogen sulfide enobuthi obukhulu. Izisetshenziswa zokuzivikela ezifanelekile (i-PPE), njengamagilavu, ukuvikela amehlo, nokuvikela ukuphefumula, kufanele kusetshenziswe njalo lapho uphatha le nhlanganisela. Ukungena komoya owanele kubalulekile ukuze kuvinjelwe ukunqwabelana kwamagesi anobuthi. Esimeni sokuchayeka, ukunakekelwa kwezempilo ngokushesha kufanele kufunelwe.

Ucwaningo Olwengeziwe

Ukuze uthole ukwaziswa okwengeziwe mayelana izakhiwo, synthesis, kanye nezicelo iron sulfide ezimbili, thintana nemibhalo yesayensi nemininingwane yolwazi efana naleyo enikezwe i-National Institute of Standards and Technology (NIST) https://www.nist.gov/. Khumbula ukuthi izinqubo zokuphatha ngokuphephile zibalulekile uma usebenza nale nhlanganisela yamakhemikhali.
