Ntau yam tseem ceeb, lossis subatomic, cov khoom ntawm cov khoom muaj cov khoom siv hluav taws xob. Piv txwv li, electrons muaj tus nqi tsis zoothiab protons muaj tus nqi zoo, tab sis neutrons muaj pes tsawg tus nqi. Yuav ua li cas them electrons e nqa?
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Rau lub xov tooj hluav taws xob hluav taws xob coj tus cwj pwm li electrolytic cell?
Lo lus teb yog qhov kev xaiv (iii) Lub xov tooj hluav taws xob hluav taws xob tuaj yeem coj tus cwj pwm zoo li lub xov tooj hluav taws xob thaum muaj ib qho kev thov ntawm ib qho kev cuam tshuam sab nraud ntawm lub galvanic cell thiab cov tshuaj tiv thaiv tsis yog inhibited kom txog thaum qhov tawm tsam qhov hluav taws xob nce mus txog tus nqi 1.
Cadmium puas yog qhov zoo ntawm cov hluav taws xob thiab hluav taws xob?
Vim nws qhov ua tau zoo raws li tus neeg xyuas hluav taws xob, cadmium feem ntau siv hauv electroplating thiab hauv roj teeb. Tsis tas li ntawd, cadmium thiab cov kev daws teeb meem ntawm nws cov tebchaw yog tshuaj lom thiab yuav tsum tau ua tib zoo saib xyuas.
