14.9. 1 Kev Taw Qhia. Ib chav kawm tshiab ntawm cov khoom siv superconducting, cov tooj liab oxides siab (feem ntau hu ua cuprates), tau tshawb pom los ntawm Bednroz thiab Muller hauv xyoo 1986.
cuprous oxide yog dab tsi?
Copper(I) oxide los yog cuprous oxide yog cov inorganic compound nrog formula Cu2O. Nws yog ib qho tseem ceeb oxides ntawm tooj liab, lwm yam yog tooj liab (II) oxide los yog cupric oxide (CuO). Cov khoom xim liab no yog ib feem ntawm qee cov xim pleev xim.
cuprous oxide tsim li cas?
Nws tuaj yeem tsim los ntawm cua sov tooj liab hauv huab cua ntawm thaj tsam 300–800 ° C: 2 Cu + O2 → 2 CuO Rau kev sim siv, ntshiab tooj liab (II) oxide yog npaj zoo dua los ntawm cua sov tooj liab (II) nitrate, tooj liab (II) hydroxide, los yog tooj liab (II) carbonate: 2 Cu(NO3)2(s) → 2 CuO (s) + 4 NO2 (g) + O2( g) (180°C)
cuprous oxide siv rau dab tsi?
valences: cuprous oxide, Cu2O, thiab cupric oxide, CuO. Cuprous oxide, cov khoom siv crystalline liab, tuaj yeem tsim los ntawm electrolytic lossis rauv txoj kev. Nws raug txo kom yooj yim los ntawm hydrogen, carbon monoxide, charcoal, lossis hlau rau hlau tooj liab. Nws muab cov xim liab rau iav thiab siv rau cov xim pleev xim rau
Puas muaj cuo2?
tooj liab oxides muaj nyob rau hauv ob hom: cupric oxide (CuO) thiab cuprous oxide (Cu2O), nyob ntawm lub xeev valence ntawm tooj.

Leej twg yog thawj tus neeg nrhiav tau chocolate?
Kev tsim thawj cov qhob noom xim kasfes niaj hnub no tau lees paub rau Joseph Fry, uas xyoo 1847 tau pom tias nws tuaj yeem ua cov qhob noom xim kasfes los ntawm kev ntxiv cov kua nplaum nplaum nplaum rov qab rau hauv Dutch cocoa..

Ib hnub xyoo 1910, American geneticist Thomas Hunt Morgan peered los ntawm ib txhais tes lens ntawm ib tug txiv neej txiv hmab txiv ntoo ya, thiab nws pom nws tsis zoo. Es tsis txhob muaj lub qhov muag liab ci ntsa iab ntawm cov tsiaj qus Drosophila melanogaster, tus yoov no muaj qhov muag dawb .
Leej twg nrhiav tau aberration ntawm lub hnub qub?
Qhov kev hloov pauv tiag tiag ntawm lub hnub qub vim yog aberra tion tsis tuaj yeem pom ncaj qha, tab sis cov kev hloov pauv hauv qhov kev hloov pauv no tuaj yeem ua tau. Nws yog los ntawm kev ua raws li kev hloov pauv ntawm ntau lub hnub qub uas tus kws tshawb fawb Askiv James Bradleynrhiav pom stellar aberration thaum ntxov xyoo pua 18th .
Leej twg yuav tsum noj magnesium oxide?
