Qhov sib txawv tseem ceeb ntawm zinc thiab zinc oxide yog tias zinc yog cov tshuaj lom neeg thaum zinc oxide yog cov tshuaj lom neeg.
Zinc yog cov tshuaj lom neeg hlau nyob hauv d block ntawm lub sijhawm ntu ntawm cov ntsiab lus. Nws tsim ntau cov tebchaw xws li oxides, sulfides, thiab lwm yam. Zinc oxide yog ib yam tshuaj lom neeg uas muaj zinc thiab oxygen atoms. Nws tshwm sim raws li cov khoom dawb. Cia peb tham ntxiv txog zinc thiab nws cov oxide hauv qab no.
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 ob lub ntsiab lus qhia +2 oxidation xeev raws li lub xeev oxidation ruaj khov thiab tseem Mg+2 thiab Zn+2 cations yog ntawm zoo sib xws. Ntxiv mus, qhov no yog 24th cov tshuaj lom neeg ntau tshaj plaws nyob rau hauv lub ntiaj teb crust. Qee cov lus tseeb txog zinc muaj raws li hauv qab no:
- Tshuaj cim - Zn
- Tus lej Atomic - 30
- Standard atomic hnyav - 65.38
- Zoo - nyiaj grey khoom
- Group – 12
- Lub Sijhawm - 4
- Block – d block
- Element qeb – post-transition metal
- Electron configuration – [Ar] 3d10 4s2
- Phase ntawm tus qauv kub thiab siab - theem khoom
- Melting point – 419.53 °C
- Boiling point – 907 °C
- Crystal qauv - hcp (hexagonal kaw-packed)
Thaum xav txog cov hlau zinc, 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 ua tau zoo nyob rau 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 cov ntsiab lus melting tsawg thiab boiling thaum piv rau feem ntau lwm yam hlau.
Daim duab 01: Zinc Hlau
Thaum xav txog qhov tshwm sim ntawm cov hlau no, lub ntiaj teb pob zeb muaj li 0.0075% ntawm zinc. Peb Cn pom cov khoom no nyob rau hauv av, dej hiav txwv, tooj liab thiab lead ores, thiab lwm yam. Ntxiv mus, cov khoom no feem ntau yuav pom nyob rau hauv ua ke nrog sulfur.
Zinc Oxide yog dab tsi?
Zinc oxide yog cov tshuaj sib xyaw uas muaj cov tshuaj formula ZnO. Nws yog ib qho inorganic compound. Lub xeev oxidation ntawm zinc nyob rau hauv lub compound yog +2 thiab rau oxygen, nws yog -2. Nws zoo nkaus li cov khoom dawb uas yog insoluble hauv dej. Txawm li cas los xij, hauv qhov xwm txheej, nws tshwm sim raws li cov ntxhia Zincite; ib tug tsawg mineral. Cov ntxhia no muaj manganese thiab lwm yam impurities. Yog li ntawd, nws zoo nkaus li daj lossis xim liab. Tsis tas li ntawd, crystalline zinc oxide yog thermochromic. Nws txhais tau hais tias nws cov xim dawb hloov mus rau hauv cov xim daj thaum cua sov hauv huab cua thiab nws tuaj yeem tig rov qab mus rau xim dawb thaum txias. Qee qhov tseeb ntawm zinc oxide yog raws li nram no:
- Tshuaj formula – ZnO
- Molar mass - 81.38 g/mol
- Zoo - dawb khoom
- Phase ntawm tus qauv kub thiab siab - theem khoom
- Melting point – 1,975 °C
- Boiling point – decomposes saum 1,975 °C
- Crystal qauv - Wurtzite
Daim duab 02: Zinc Oxide
Peb siv cov khoom sib xyaw no hauv kev tsim cov roj hmab, yas, ceramics, iav, cement, lubricants, thiab lwm yam. Tsis tas li ntawd, nws muaj cov khoom siv semiconductor. Cov khoom muaj txiaj ntsig zoo uas cov khoom sib xyaw no muaj, txhawm rau siv los ua cov khoom siv hluav taws xob yog cov pob tshab, kev txav hluav taws xob siab, dav bandgap, thiab lwm yam.
Qhov txawv ntawm Zinc thiab Zinc Oxide yog dab tsi?
Zinc yog cov khoom siv tshuaj muaj tus lej atomic 30 thiab cov cim tshuaj Zn thaum zinc oxide yog cov tshuaj lom neeg muaj cov tshuaj formula ZnO. Qhov no yog qhov sib txawv tseem ceeb ntawm zinc thiab zinc oxide. Ntawd yog, zinc oxide yog ib qho inorganic compound tau los ntawm zinc chemical keeb. Nws yog ua ke nrog oxygen. Txij li zinc yog cov khoom siv tshuaj, peb tuaj yeem muab nws qhov hnyav atomic (tus qauv atomic hnyav yog 65.38 rau zinc) thaum peb tuaj yeem muab cov molar loj lossis molar hnyav rau zinc oxide (molar loj yog 81.38 g / mol.) vim tias nws yog cov tshuaj lom neeg.
Ntxiv mus, kuj tseem muaj qhov sib txawv ntawm zinc thiab zinc oxide nyob rau hauv tsos. Cov zinc zoo nkaus li cov khoom siv nyiaj-grey zoo li cov zinc oxide zoo li cov khoom dawb hauv cov qauv kub thiab siab. Tsis tas li ntawd, lwm qhov sib txawv ntawm zinc thiab zinc oxide yog tias peb tuaj yeem siv zinc oxide hauv kev npaj cov khoom siv hluav taws xob, tab sis zinc ib leeg tsis muaj cov khoom siv semiconductor.
Cov hauv qab no nthuav tawm cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm zinc thiab zinc oxide hauv daim ntawv tabular.
Summary – Zinc vs Zinc Oxide
Zinc yog ib yam tshuaj uas peb paub zoo li hlau. Zinc oxide yog ib qho inorganic compound uas muaj zinc thiab oxygen ua ke nrog ib leeg. Yog li, qhov sib txawv tseem ceeb ntawm zinc thiab zinc oxide yog zinc yog cov tshuaj lom neeg thaum zinc oxide yog cov tshuaj lom neeg.
