Qhov sib txawv tseem ceeb ntawm zinc thiab hlau yog zinc yog qhov tseem ceeb hauv kev tiv thaiv kab mob los ntawm kev txhawb lub cev tiv thaiv kab mob, whereas hlau tseem ceeb rau kev thauj mus los ntawm oxygen mus rau cov ntaub so ntswg thiab cov kab mob hauv peb lub cev.
Ob lub zine thiab hlau yog cov tshuaj tseem ceeb uas muaj lub luag haujlwm tseem ceeb hauv peb lub cev. Hlau yog cov tshuaj tseem ceeb tshaj plaws hauv lub cev, thaum zinc yog qhov tseem ceeb thib ob.
Zinc yog dab tsi?
Zinc yog cov khoom siv tshuaj muaj tus lej atomic 30 thiab cov cim tshuaj Zn. Cov tshuaj no zoo li magnesium thaum peb xav txog nws cov khoom siv tshuaj. Qhov no feem ntau yog vim hais tias ob qho tib si cov ntsiab lus qhia txog +2 oxidation xeev raws li lub xeev oxidation ruaj khov, thiab Mg + 2 thiab Zn + 2 cations yog qhov zoo sib xws. Ntxiv mus, qhov no yog 24th feem ntau cov tshuaj lom neeg nyob rau hauv lub ntiaj teb daim tawv nqaij.
Tus qauv atomic hnyav ntawm zinc yog 65.38. Nws zoo nkaus li nyiaj-grey khoom. Cov ntsiab lus no tuaj yeem pom nyob rau hauv pawg 12 thiab lub sijhawm 4 nyob rau hauv daim ntawv teev sijhawm. Yog li ntawd, nws yog ib qho d thaiv cov ntsiab lus thiab tuaj yeem categorized li cov hlau tom qab hloov pauv. Cov txheej txheem electron ntawm zinc yog [Ar]3d104s2. Nws tshwm sim hauv cov khoom hauv lub xeev ntawm qhov kub thiab txias thiab siab. Nws melting point yog hais txog 420 degrees Celsius thaum lub boiling point yog siab (907 degrees Celsius). Nws tshwm sim nyob rau hauv hexagonal kaw-packed siv lead ua qauv.
Daim duab 01: Zinc
Thaum xav txog zinc hlau, nws yog cov hlau diamagnetic thiab muaj lub ntsej muag xiav-dawb ci ntsa iab. Feem ntau qhov kub thiab txias, cov hlau no yog tawv thiab nkig. Txawm li cas los xij, nws dhau los ua malleable ntawm 100 thiab 150 ° C. Ntxiv mus, qhov no yog ib tug ncaj ncees conductor ntawm hluav taws xob. Txawm li cas los xij, nws muaj qis melting thiab boiling ntsiab lus thaum piv rau feem ntau lwm yam hlau.
Thaum xav txog qhov tshwm sim ntawm cov hlau no, lub ntiaj teb lub pob zeb muaj li 0.0075% ntawm zinc. Peb tuaj yeem pom cov khoom no hauv av, dej hiav txwv, tooj liab, lead ores, thiab lwm yam. Tsis tas li ntawd, cov khoom no feem ntau yuav pom nyob rau hauv ua ke nrog sulfur.
Hlau yog ib qho tseem ceeb ntawm peb lub cev xav tau kev loj hlob thiab kev loj hlob. Lub cev xav tau hlau rau kev tsim cov hemoglobin uas yog cov protein uas peb xav tau los thauj cov pa oxygen ntawm lub ntsws mus rau cov hlwb. Peb kuj xav tau hlau rau kev tsim cov myoglobin.
Iron yog dab tsi?
Hlau yog cov khoom siv tshuaj muaj cov tshuaj Fe thiab atomic naj npawb 26. Nws yog cov hlau uas tuaj hauv thawj qhov kev hloov pauv. Hlau yog cov tshuaj lom neeg feem ntau hauv ntiaj teb.
Daim duab 02: Hlau
Iron yog ib qho khoom ntawm qhov kub thiab txias. Lub melting point yog 1538 degrees Celsius, thiab lub boiling point yog 2862 degrees Celsius. Qhov ceev ntawm cov hlau no yog siab heev thiab nyob ib ncig ntawm 7.8 g / cm3. Thaum nws yog liquefied, nws muaj qhov ceev, uas yog nyob ib ncig ntawm 6.98 g / cm3. Muaj ob hom qauv siv lead ua muaj nyob hauv cov hlau: lub cev-centered cubic qauv thiab lub ntsej muag-centered cubic qauv. Qhov feem ntau oxidation xeev ntawm hlau yog +2 thiab +3. Ntxiv mus, muaj plaub hom allotropes ntawm hlau hu ua alpha, gamma, theta, thiab epsilon. Peb tuaj yeem soj ntsuam thawj peb qhov allotropes hauv cov xwm txheej zoo tib yam.
Muaj ntau yam kev siv hlau - feem ntau yog cov hlau yooj yim rau kev tsim cov hlau, ua cov khoom siv rau kev tsim kho, ntxiv rau cov hlau tsis muaj peev xwm anemia, thiab lwm yam.
Zinc yog ib qho ntxhia ntxhia uas peb lub cev xav tau me me. Tab sis peb tseem xav tau cov ntxhia no rau kev ua haujlwm zoo ntawm yuav luag 100 enzymes uas tsim nyog rau kev ua haujlwm ntawm lub cev. Cov ntxhia no tseem ceeb rau kev tsim DNA, kev loj hlob ntawm cov hlwb, tsim cov proteins, kho cov ntaub so ntswg puas, thiab txhawb kev tiv thaiv kab mob.
Qhov txawv ntawm Zinc thiab Hlau yog dab tsi?
Qhov sib txawv tseem ceeb ntawm zinc thiab hlau yog zinc yog qhov tseem ceeb hauv kev tiv thaiv kab mob los ntawm kev txhawb lub cev tiv thaiv kab mob, thaum hlau tseem ceeb rau kev thauj mus los ntawm oxygen mus rau cov ntaub so ntswg thiab kab mob hauv peb lub cev. Tag nrho cov nplej, mis nyuj, oysters, nqaij liab, nqaij qaib, thiab lwm yam, yog qhov chaw ntawm zinc, thaum nqaij liab, nqaij npuas, nqaij nruab deg, taum, zaub ntsuab nplooj ntsuab, thiab lwm yam, yog qhov chaw ntawm hlau.
Summary – Zinc vs Iron
Qhov sib txawv tseem ceeb ntawm zinc thiab hlau yog zinc yog qhov tseem ceeb hauv kev tiv thaiv kab mob los ntawm kev txhawb lub cev tiv thaiv kab mob, whereas hlau tseem ceeb rau kev thauj mus los ntawm oxygen mus rau cov ntaub so ntswg thiab cov kab mob hauv peb lub cev.
