Uyini umehluko phakathi kwe-zinc ne-magnesium?

Umehluko osemqoka phakathi kwe-zinc ne-magnesium ukuthi i-zinc iyinsimbi ye-post-transition, kanti ama-magnesium yinsimbi yomhlaba we-alkaline.
I-Zinc ne-Magnesium yizinto zamakhemikhali zethebula lesikhathi. Lezi zinto zamakhemikhali zenzeka ikakhulukazi njengezinsimbi. Kodwa-ke, banezindawo ezahlukahlukene zamakhemikhali nezomzimba ngenxa yokucushwa kwe-elekthly ahlukahlukene.

Yini i-zinc?

I-Zinc yinto yamakhemikhali enenombolo ye-athomu 30 nophawu lwamakhemikhali zn. Le nto yamakhemikhali ifana ne-magnesium lapho sibheka izakhiwo zayo zamakhemikhali. Lokhu kungenxa yokuthi zombili lezi zinto zibonisa isimo se-oxidation esibonisa njengezwe elizinzile le-opidation, futhi i-MG + 2 ne-ZN + amaza ka-ZN asayizi afanayo. Ngaphezu kwalokho, le yinto eyi-24th yamakhemikhali enkulu kunazo zonke emhlabeni.

Isisindo esijwayelekile se-athomu se-atomic se-zinc singama-65.38, futhi sivela njengesiliva-grey eliqinile. Kuseqenjini le-12 kanye nenkathi engu-4 yetafula lesikhathi. Le nto yamakhemikhali ingeka-D block of Elements, futhi iza ngaphansi kwesigaba sensimbi ye-post-transition. Ngaphezu kwalokho, i-zinc iqinile ekushiseni okujwayelekile nengcindezi. Inesakhiwo se-crystal sesakhiwo esiseduze se-hexagonal.

I-Zinc Metal iyinsimbi ye-diamagnetic futhi inokubukeka okukhanyayo okumhlophe. Emazingeni okushisa amaningi, le mota ilukhuni futhi i-brittle. Kodwa-ke, iyabaleka, phakathi kuka-100 no-150 ° C. Ngaphezu kwalokho, lokhu kungumqhubi ofanele kagesi. Kodwa-ke, inamaphoyinti aphansi futhi abilayo uma kuqhathaniswa nezinye izinsimbi eziningi.

Lapho ubheka ukuvela kwalesi sinsimbi, i-crust yomhlaba ine-0.0075% ye-zinc. Singathola le nto emhlabathini, amanzi olwandle, ethusi, kanye ne-ores, njll. Ngaphezu kwalokho, le nto kungenzeka ukuthi itholakale ngokuhlanganiswa nesibabule.

Yini i-magnesium?

I-Magnesium yinto yamakhemikhali enenombolo ye-athomu 12 nophawu lwamakhemikhali mg. Le nto yamakhemikhali yenzeka njenge-grey-Shiny-Shiny Shing Card yokushisa yasekamelweni. Kuseqenjini 2, isikhathi 3, etafuleni lesikhathi. Ngakho-ke, singakuqamba njengento ye-S-block. Ngaphezu kwalokho, i-magnesium iyinsimbi yomhlaba we-alkaline yomhlaba (amaqembu 2 amakhemikhali izinto abizwa ngegama elithi Alkaline Earth Metals). Ukucushwa kwe-elektroni kwalesi sinsimbi [nge-3S2.

I-Magnesium Metal iyinto eningi yamakhemikhali endaweni yonke. Ngokwemvelo, le metal yenzeka ngokuhlanganiswa nezinye izinto zamakhemikhali. Ngaphandle kwalokho, isimo se-oxidation se-magnesium singuye +2. Insimbi yamahhala iyasebenza kakhulu, kepha singayikhiqiza njengento yokwenziwa. Kungashisa, kukhiqize ukukhanya okukhanyayo kakhulu. Sikubiza ngokuthi ukukhanya okumhlophe okukhanyayo. Singathola i-magnesium nge-electrolysis yama-magnesium usawoti. Lolu usawoti wama-magnesium lutholakala nge-brine.

I-Magnesium iyinsimbi engasindi, futhi inamanani aphansi kakhulu ngokuncibilika kwamaphoyinti ancibilikayo phakathi kwama-alkaline ndl. Le nsimbi ibuye futhi i-brocture futhi inenkinga kalula kanye namabhendi we-shear. Lapho kuhlanganiswe nge-aluminium, i-alloy iba yi-ductile enkulu.

Ukusabela phakathi kwe-magnesium namanzi akusheshi njenge-calcium nezinye izinsimbi zomhlaba we-alkaline. Lapho sifaka ucezu lwe-magnesium emanzini, singabona ama-bubbles we-hydrogen aqhamuke endaweni yensimbi. Kodwa-ke, ukusabela kusheshisa ngamanzi ashisayo. Ngaphezu kwalokho, le metal ingasabela ngama-acid actherthermy, isib, i-hydrochloric acid (hcl).

Uyini umehluko phakathi kwe-zinc ne-magnesium?

I-Zinc ne-Magnesium yizinto zamakhemikhali zethebula lesikhathi. I-Zinc iyinto yamakhemikhali enenombolo ye-athomu 30 nophawu lwamakhemikhali i-ZN, ngenkathi i-magnesium yinto yamakhemikhali enenombolo ye-athomu 12 nophawu lwamakhemikhali mg. Umehluko osemqoka phakathi kwe-zinc ne-magnesium ukuthi i-zinc iyinsimbi ye-post-transition, kanti ama-magnesium yinsimbi yomhlaba we-alkaline. Ngaphezu kwalokho, i-zinc isetshenziswa ekukhiqizweni kwama-alloys, i-galvaning, izingxenye zezimoto, izingxenye zikagesi, njll., Ngenkathi i-magnesium isetshenziswa njengengxenye ye-aluminium alloys. Lokhu kufaka phakathi ama-alloys asetshenziswa kumathini we-aluminium beverage. I-Magnesium, ihlanganiswe ne-zinc, isetshenziswa ekufeni kokufa.
