hao lua sulfide

ʻO ka hao ʻelua Sulfide: He Alakaʻi Kūikawā ʻO ka hao ʻelua sulfide, ʻike ʻia hoʻi ʻo ferrous sulfide, he hui kemika me ke ʻano FeS. Hāʻawi kēia alakaʻi i kahi hiʻohiʻona piha o kāna mau waiwai, synthesis, noi, a me nā noʻonoʻo palekana.

Na waiwai o ka hao elua sulfide

ʻElua sulfide hao Aia i loko o nā ʻano crystalline, ʻo ka mea maʻamau ka mineral pyrrhotite kūlohelohe. Hōʻike pinepine kēia mineral i kahi haku mele ʻole-stoichiometric, ʻo ia hoʻi, hiki ke ʻokoʻa iki ka ratio o ka hao me ka sulfur. Maʻemaʻe hao lua sulfide he paʻa hina ʻeleʻele a ʻeleʻele. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai akā hoʻopili ʻia me nā ʻakika e hana i ke kinoea hydrogen sulfide, kahi mea ʻawaʻawa a hiki ke puhi ʻia. He kiʻekiʻe kona wahi heheʻe, ma kahi o 1195 °C (2183 °F).

Na Waiwai Kino

| Waiwai | Waiwai ||----------------|--------------------------------------|| Hua'ōlelo Kimia | FeS || Molar Mass | 87.91 g/mol || Ka nui | 4.7–5.0 g/cm3 || Lae hehee | 1195 °C (2183 °F) || Ke nana aku | ʻeleʻele hina a ʻeleʻele ʻeleʻele paʻa |

Na Waiwai Kemika

ʻElua sulfide hao hiki ke hoʻololi me nā ʻakika, e like me ka ʻakika hydrochloric (HCl), e hana i ke kinoea hydrogen sulfide (H?S):FeS(s) + 2HCl(aq) → FeCl?(aq) + H?S(g)Hoʻohana pinepine ʻia kēia hopena i ka hoʻomākaukau ʻana o ka hydrogen sulfide. Hiki ke hoʻokō ʻia ka hopena me ka oxygen, e alakaʻi ana i ka hoʻokumu ʻana o ka hao a me ka sulfur dioxide.

Hoʻohui ʻia o ka hao ʻelua Sulfide

ʻElua sulfide hao hiki ke synthesized ma kekahi mau ala. ʻO ke ʻano maʻamau ka hoʻopili pololei ʻana i ka hao me ka sulfur ma nā wela kiʻekiʻe:Fe(s) + S(s) → FeS(s)He exothermic loa kēia hopena a pono e hoʻomalu pono e pale i ka hoʻomehana ʻole ʻia. ʻO kekahi ʻano hana ʻē aʻe e pili ana i ka hopena o ka ua ma waena o ka paʻakai soluble(II) a me ka paʻakai sulfide hiki ke hoʻoheheʻe ʻia:FeCl?(aq) + Na?S(aq) → FeS(s) + 2NaCl(aq)Hiki kēia ʻano i kahi ea o hao lua sulfide a laila hiki ke kānana a maloʻo.

No ka Hao Elua Sulfide

ʻElua sulfide hao loaʻa nā noi ma nā ʻoihana like ʻole. ʻO kekahi noi koʻikoʻi i ka hana ʻana i ke kinoea hydrogen sulfide, i hoʻohana ʻia i nā kaʻina hana ʻoihana like ʻole a ma ke ʻano he reagent i ka synthesis kemika. He hana hoʻi ʻo ia i ka metallurgy o ka hao a me ke kila, e hana ana i kumu o ka sulfur. Eia kekahi, he mea ia i loko o kekahi mau puaʻa. Eia nō naʻe, ma muli o ka ʻawaʻawa o nā kinoea i hana ʻia e ia, pono ka hoʻohana ʻana i ka mālama palekana nui.

Nā Manaʻo palekana

He mea nui e lawelawe hao lua sulfide me ka akahele ma muli o kona hiki ke hana me nā ʻakika e hana i ke kinoea hydrogen sulfide ʻona loa. Pono e hoʻohana mau ʻia nā lako pale pilikino (PPE), e like me nā mīkina lima, ka pale maka, a me ka pale hanu i ka wā e lawelawe ai i kēia pūhui. Pono ka ea ea kūpono e pale ai i ke kūkulu ʻia ʻana o nā kinoea ʻona. Inā ʻike ʻia, pono e ʻimi koke i ka lāʻau lapaʻau.

Noi hou aku

No ka ʻike kikoʻī e pili ana i nā waiwai, synthesis, a me nā noi o hao lua sulfide, e ʻimi i nā palapala ʻepekema a me nā ʻikepili e like me nā mea i hāʻawi ʻia e ka National Institute of Standards and Technology (NIST) https://www.nist.gov/. E hoʻomanaʻo he mea nui nā kaʻina hana palekana i ka wā e hana ai me kēia pūhui kemika.
