Cobalt thiab Nonmetals
Cobalt kuj daim ntawv cog lus nrog cov tshuaj chlorine los tsim cobalt chloride thiab oxygen los tsim cobalt oxide. Cobalt oxide yog tshwj xeeb tshaj yog muaj nuj nqis thiab ntau raws li nws yog cov cobalt complex uas yog siv los muab cov xim xiav rau iav uas tsis yooj yim rau kev sib txuas
Tsis tas li cov lus nug yog, hom ntawv cog lus twg cobalt tsim?
Cov lus teb yog (3) hlau. Cobalt yog ib qho kev hloov hlau, yog li nws tsis tuaj yeem ua covalent daim ntawv cog lus , qho daim ntawv cog lus non-metals, yog li tshem tawm xaiv 1 thiab 2. Ionic daim ntawv cog lus nyob nruab nrab ntawm cov hlau thiab cov hlau tsis yog hlau, tab sis cov khoom cobalt ua tsis muaj hlau tsis muaj hlau, tshem tawm xaiv 4 thiab.
Tom qab, lo lus nug yog, dab tsi yog cobalt pom nyob rau hauv? 1735 ib
Kuj Paub, yog Cobalt polar lossis nonpolar?
Cobalt thiab bromine, ΔEN = 0.9, polar covalent.
Cobalt tseem hu ua dab tsi?
Cobalt (Symbol Co, tus naj npawb 27) yog ib qho tshuaj lom neeg tshwm sim ib txwm muaj nyob rau hauv daim ntawv sib xyaw ua ke. Thaum sib cais, nws yog ib tug silver-grey, lustrous, tawv hlau. Cov hlau no yog kuj hu ua goblin ore (German) vim yog xim xiav nws tsim thiab vim tias nws muab cov pa phem tawm thaum smelting.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Puas yog cobalt muaj cov isotopes?
Isotopes: Cobalt muaj 22 isotopes uas nws ib nrab-lub neej paub, nrog cov lej loj 50 txog 72. Qhov tshwm sim ntawm cobalt muaj nws ib qho isotope ruaj khov, 59Co
