Isotopes : Cobalt muaj 22 isotopes nws ib nrab-lub neej paub, nrog huab hwm coj 50 mus rau 72. Ib txwm tshwm sim cobalt muaj nws ib qho ruaj khov isotope , 59Co.
Hauv qhov no, dab tsi yog qhov feem ntau isotope ntawm cobalt?
Isotopes ntawm cobalt
| Isotope | lwj | |
|---|---|---|
| kev nplua nuj | khoom | |
| 58Co | syn | 58Fe |
| 59Co | 100% | ruaj khov |
| 60Co | syn | 60Ni |
Dab tsi yog cov khoom ua los ntawm cobalt? Cobalt iav insulators, xim xim, xyaum, milling khoom thiab steel alloy yog tag nrho cov khoom ua nrog cobalt . Cobalt steel yog tawv, muaj zog thiab kub-resistant txaus ua rau hauv qhov chaw rau dav hlau cav thiab propellers.
Qhov thib ob, kev siv cov isotope ntawm cobalt yog dab tsi?
Cobalt -60. Cobalt -60 (60Co) ua siv rau radiotherapy kev kho mob qog noj ntshav, zaub mov irradiation thiab cov ntawv thov kev lag luam. Raws li cobalt -60 decays rau hauv ib tug ruaj khov nickel-60 isotope , ob lub wavelengths ntawm high-zog gamma-rays raug tso tawm (1.17 thiab 1.33 MeV- nruab nrab ntawm 1.25 MeV siv ).
Dab tsi yog qhov luster ntawm cobalt?
nws yog xim hlau

Puas yog ib qho tsis muaj polar molecule puas muaj hydrogen bonding?
Yog hais tias lub molecule tsis yog polar, ces tsis muaj kev sib cuam tshuam dipole-dipole los yog hydrogen bonding tuaj yeem tshwm sim thiab tsuas yog ua tau intermolecular quab yuam yog lub zog van der Waals tsis muaj zog
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
Puas muaj zog npaum li cas yog cov kua qaub los yog cov hauv paus daws teeb meem?
Qhov ntau ntawm 0 mus rau 14 muab kev ntsuas ntawm kev sib piv lub zog ntawm cov kua qaub thiab cov hauv paus daws teeb meem. Cov dej ntshiab thiab lwm cov kev daws teeb meem nruab nrab muaj tus nqi pH ntawm 7. Tus nqi pH tsawg dua 7 qhia tias cov kua qaub yog acidic, thiab pH tus nqi ntau dua 7 qhia tias cov tshuaj yog qhov yooj yim
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Puas yog argon muaj cov isotopes?
Argon (18Ar) muaj 26 lub npe isotopes, los ntawm 29Ar mus rau 54Ar thiab 1 isomer (32mAr), ntawm peb qhov ruaj khov (36Ar, 38Ar, thiab 40Ar). Hauv ntiaj teb, 40Ar ua rau 99.6% ntawm ntuj argon. Tag nrho lwm cov isotopes muaj ib nrab lub neej tsawg dua ob teev, thiab feem ntau tsawg dua ib feeb
