Nguwuphi umahluko phakathi kwe-zinc kunye ne-magnesium?

Umahluko ophambili phakathi kwe-zinc kunye ne-signesium kukuba i-zinc yintsimbi yeposi yeposi, ngelixa i-magnesium yintsimbi ye-alkaline yomhlaba.
I-zinc kunye ne-magnesium zizinto zekhemikhali zetafile yexesha. Ezi zinto zekhemikhali zenzeka ikakhulu njengeentsimbi. Nangona kunjalo, banepropathi eyahlukeneyo yemichiza kunye nezamzimba ngenxa yokuHlanganelwa kombane okwahlukileyo.

Yintoni i-zinc?

I-Zinc yinto yekhemikhali enenombolo ye-atomic 30 kunye nophawu lweekhemikhali ze-zn. Eli nqaku lekhemikhali lifana ne-magnesium xa sijonga iipropathi zekhemikhali. Oku kungenxa yokuba zombini ezi zinto zibonisa imeko ye-AIMIDOTION ye-A +2 njengendawo ezinzileyo ye-oxido, kunye ne-MG + 2 kunye neZN + 2 ii-cutions zobukhulu obufanayo. Ngapha koko, le yi-24 ka-24 kaninzi kakhulu ikhemikhali lekhemikhali emhlabeni.

Ubunzima be-atomic esemgangathweni ye-zinc yi-65.38, kwaye ibonakala njengesilivere-grey eqinileyo. Kukwiqela le-12 kunye nexesha le-4 letafile yexesha. Eli nqaku lekhemikhali leli block yezinto, kwaye iza phantsi kodidi lwentsimbi ye-post. Ngapha koko, i-zinc iqinile kubushushu obuqhelekileyo kunye noxinzelelo. Inesakhiwo sekristali ye-shexagonal sheat.

I-winc intsimbi yentsimbi ye-dieamagnetic kwaye inembonakalo emhlophe emhlophe. Kubushushu obuninzi, le ntsimbi inzima kwaye ibrittle. Nangona kunjalo, kuya kuba lula, phakathi kwe-100 ne-150 ° C. Ngapha koko, lo ngumqhubi ofanelekileyo wombane. Nangona kunjalo, inezinyibilikisi eziphantsi kwaye zibilayo xa kuthelekiswa nezinye izinyithi.

Xa ujonga ukuvela kwesinyithi, i-rust yomhlaba inama-0.0075% ye-zinc. Singayifumana le nto kumhlaba, amanzi olwandle, ubhedu, kunye ne-ores ekhokelayo, njl. Ukongeza, le nto inokwenzeka ifumaneka ngokudibeneyo ne-sulfure.

Yintoni i-magnesium?

I-magnesiyom yindawo yemichiza enenombolo ye-atomic 12 kunye nophawu lwekhemikhali mg. Eli nqaku lekhemikhali lenzekile njenge-grey-finy uqinile kubushushu begumbi. Kukwiqela 2, i-3, kwitafile yexesha elidlulileyo. Ke ngoko, sinokuyibiza njengento ye-S-block. Ngapha koko, i-magnesium yintsimbi ye-alkali ene-alkali Ukucwangciswa kwe-Elerron kwale ntsimbi [ne] 3s2.

I-Magnesium yentsimbi yindawo enkulu yekhemikhali kwindalo iphela. Ngokwemvelo, le ntsimbi yenzeka ngokudibeneyo nezinye izinto zekhemikhali. Ngaphandle koko, imeko ye-oxidation ye-magnesium ngu- +2. Intsimbi yasimahla isebenza kakhulu, kodwa sinokuyivelisa njengezinto zokwenziwa. Inokuvutha, ivelise ukukhanya okuqaqambileyo. Siyibiza ngokuba sisibane esimhlophe esimhlophe. Singafumana i-magnesium ngokutsala i-electrolysis ye-magnesium ye-magnesium. Ezi zitya ze-magnesium zinokufumaneka kwi-brine.

I-magnesium sisinyithi esikhanyayo, kwaye inamaxabiso asezantsi okunyibilika kunye namanqaku abilayo phakathi kweZinyithi zaseAlkaline. Esi sinyithi sikwaBrittle kwaye silula phantsi kwenziwe iqhekeza kunye neebhendi zamachiza. Xa yabelwe i-aluminium, i-alloy iba yigun.

Ukuphendula phakathi kwe-magnesium kunye namanzi abukhawulezile njenge-calcium kunye nezinye izinyithi zomhlaba zase-Alkaline. Xa sisenza isiqwenga se-magnesium emanzini, sinokujonga amaqabu e-hydrogen avele kumphezulu wensimbi. Nangona kunjalo, impendulo isantya ngamanzi ashushu. Ngapha koko, le ntsimbi inokusabela nge-asidi, umzekelo, i-hydrochloric acid (i-HCL).

I-zinc kunye ne-magnesium zizinto zekhemikhali zetafile yexesha. I-Zinc yindawo yekhemikhali enenombolo ye-atomic 30 kunye nophawu lwekhemikhali lwe-zn, ngelixa i-magnesium yindawo yemichiza enenombolo ye-atomic enenombolo ye-12 kunye nekhemikhali mg. Umahluko ophambili phakathi kwe-zinc kunye ne-signesium kukuba i-zinc yintsimbi yeposi yeposi, ngelixa i-magnesium yintsimbi ye-alkaline yomhlaba. Ngaphaya koko, i-zinc isetyenziswa kwimveliso ye-alloys, i-GATVANIF, i-AFOSMOBILE, izinto zombane, njl njl, ngelixa i-magnesium isetyenziswa njengenxalenye ye-allomium alloys. Oku kubandakanya izabelo ezisetyenzisiweyo kwi-Aluminium ye-Alumnum. I-magnesium, yabelwe i-zinc, isetyenziswa ekuphoseni.
