Chemical formula: CaO2
Ntawm no, CaO tus nqi yog dab tsi?
Hauv CaO , calcium yog cation thiab oxygen yog anion. Cov nqi ntawm oxygen atom yog -2. Yog li ntawd, lub nqi nyob rau hauv calcium CaO yog +2.
Ib yam li ntawd, koj sau cov calcium oxide li cas? Cov mis rau calcium oxide yog CaO. Qhov sib xyaw no yog ionic uas txhais tau hais tias qhov zoo them ion, cation, muaj electrostatic attraction rau oxygen, uas yog tsis zoo them, anion.
Hauv kev hais txog qhov no, calcium peroxide siv rau dab tsi?
Feem ntau calcium peroxide yog siv li ib lub khob noom cookie txias los yog rau kev kho av (decontamination). Thaum twg siv hauv khob noom, calcium peroxide yog decomposed thaum ci. Ib txhia calcium peroxide yog siv hauv tshuaj txhuam hniav raws li ib tug whitener.
Calcium thiab oxygen tsim calcium oxide li cas?
Cov qauv thiab cov qauv: Calcium oxide Cov mis mos yog CaO thiab nws cov molar loj hauv 56.0774 g mol-1. Lub molecule yog tsim los ntawm cov calcium kev Ca+2 thiab cov oxygen anion O-2, qho daim ntawv ib daim ntawv cog lus ionic. Nws yog soluble hauv dej, reacting rau tsim calcium hydroxide . Calcium oxide yog insoluble hauv methanol thiab ethyl ether.

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?

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
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
