Kodi Kusiyanitsa Pakati pa Zinc ndi Magnesium Ndi Chiyani?

Kusiyana kwakukulu pakati pa zinki ndi magnesium ndikuti zinki ndi chitsulo chapambuyo pakusintha, pomwe magnesium ndi chitsulo chamchere.
Zinc ndi magnesium ndi zinthu zamagulu a tebulo la periodic.Mankhwalawa amapezeka makamaka ngati zitsulo.Komabe, ali ndi mankhwala osiyanasiyana komanso thupi chifukwa cha ma elekitironi osiyanasiyana.

Zinc ndi chiyani?

Zinc ndi mankhwala omwe ali ndi nambala ya atomiki 30 ndi chizindikiro cha mankhwala Zn.Mankhwalawa amafanana ndi magnesium tikaganizira za mankhwala ake.Izi makamaka chifukwa zinthu zonsezi zimasonyeza +2 oxidation state monga stable oxidation state, ndi Mg + 2 ndi Zn + 2 cations ndi ofanana kukula.Komanso, iyi ndi nambala 24 pa nambala 24 yomwe ili ndi makemikolo ambiri padziko lapansi.

Kulemera kwa atomiki kwa zinki ndi 65.38, ndipo kumawoneka ngati kulimba kwa silver-grey.Ili mu gulu 12 ndi periodic 4 ya tebulo la periodic.Mankhwalawa ndi a d block of element, ndipo amabwera pansi pa gulu lachitsulo la post-transition.Komanso, zinc ndi olimba pa kutentha wamba ndi kuthamanga.Ili ndi mawonekedwe a kristalo a hexagonal pafupi-odzaza.

Zinc chitsulo ndi diamagnetic chitsulo ndipo ali ndi bluish-woyera kuwala.Kutentha kwambiri, chitsulo ichi chimakhala cholimba komanso chophwanyika.Komabe, imakhala yosalala, pakati pa 100 ndi 150 ° C.Kuphatikiza apo, iyi ndi kondakitala wabwino wamagetsi.Komabe, ili ndi malo otsika osungunuka ndi otentha poyerekeza ndi zitsulo zina zambiri.

Poganizira za kupezeka kwa chitsulo ichi, kutumphuka kwa dziko lapansi kumakhala pafupifupi 0.0075% ya zinki.Tikhoza kupeza chinthu ichi m'nthaka, m'madzi a m'nyanja, mkuwa, ndi miyala yamchere, ndi zina zotero. Kuphatikiza apo, chinthu ichi chikhoza kupezeka pamodzi ndi sulfure.

Magnesium ndi chiyani?

Magnesium ndi chinthu chomwe chili ndi atomiki nambala 12 ndi chizindikiro cha mankhwala Mg.Mankhwalawa amapezeka ngati chotuwa-chonyezimira cholimba ndi kutentha kwapakati.Ili mu gulu 2, periodic 3, mu periodic table.Chifukwa chake, titha kuyitcha ngati s-block element.Kuphatikiza apo, magnesiamu ndi zitsulo zamchere zamchere (gulu la 2 lamankhwala limatchedwa zitsulo zamchere zamchere).Kusintha kwa ma elekitironi kwachitsulo ichi ndi [Ne]3s2.

Magnesium chitsulo ndi mankhwala ochuluka m'chilengedwe chonse.Mwachibadwa, chitsulo ichi chimapezeka pamodzi ndi zinthu zina za mankhwala.Kupatula apo, mkhalidwe wa okosijeni wa magnesium ndi +2.Chitsulo chaulere chimakhala chokhazikika, koma titha kuchipanga ngati chinthu chopangira.Ikhoza kuyaka, kutulutsa kuwala kowala kwambiri.Timachitcha kuwala koyera kowala.Titha kupeza magnesium ndi electrolysis ya mchere wa magnesium.Mchere wa magnesiumwu umapezeka kuchokera ku brine.

Magnesium ndi chitsulo chopepuka, ndipo chimakhala ndi zinthu zotsika kwambiri pakusungunuka ndi kuwira pakati pa zitsulo zamchere zamchere.Chitsulochi chimakhalanso chophwanyika ndipo chimasweka mosavuta pamodzi ndi zometa ubweya.Akaphatikizidwa ndi aluminiyamu, aloyiyo imakhala ductile kwambiri.

Zomwe zimachitika pakati pa magnesium ndi madzi sizofulumira ngati calcium ndi zitsulo zina zamchere zamchere.Tikamiza chidutswa cha magnesiamu m'madzi, timatha kuwona ming'alu ya haidrojeni ikutuluka pamwamba pazitsulo.Komabe, zomwe zimachitika zimathamanga ndi madzi otentha.Komanso, chitsulo ichi amatha kuchita ndi zidulo exothermally, mwachitsanzo, hydrochloric acid (HCl).

Kodi Kusiyanitsa Pakati pa Zinc ndi Magnesium ndi Chiyani?

Zinc ndi magnesium ndi zinthu zamagulu a tebulo la periodic.Zinc ndi mankhwala okhala ndi nambala ya atomiki 30 ndi chizindikiro cha mankhwala Zn, pamene magnesiamu ndi mankhwala okhala ndi atomiki nambala 12 ndi chizindikiro cha mankhwala Mg.Kusiyana kwakukulu pakati pa zinki ndi magnesium ndikuti zinki ndi chitsulo chapambuyo pakusintha, pomwe magnesium ndi chitsulo chamchere.Kuphatikiza apo, zinc imagwiritsidwa ntchito popanga ma alloys, galvanizing, zida zamagalimoto, zida zamagetsi, ndi zina zambiri, pomwe magnesium imagwiritsidwa ntchito ngati gawo la ma aluminiyamu.Izi zikuphatikizapo ma alloys omwe amagwiritsidwa ntchito muzitini zakumwa za aluminium.Magnesium, yopangidwa ndi zinc, imagwiritsidwa ntchito poponya kufa.
