Rau ntau cov khib nyiab yaj hauv cov dej ua kua, solubility nce nrog qhov kub thiab txiasKev nce hauv lub zog kinetic uas los nrog qhov kub siab dua tso cai rau cov kuab tshuaj molecules kom zoo dua sib cais cov kuab tshuaj molecules uas tau tuav ua ke los ntawm kev sib txuas lus sib txuas.
3 yam uas tuaj yeem ua rau kom muaj kev sib haum xeeb ntawm cov kua nplaum?
Peb txoj kev uas kuv tuaj yeem tuaj yeem yog nce qhov kub, nce cov kuab tshuaj, thiab siv cov kuab tshuaj nrog cov polarity zoo ib yam li cov kuab tshuaj.
Yam dab tsi cuam tshuam rau solubility ntawm cov khoom?
Solubility yog qhov siab tshaj plaws ntawm cov khoom uas yuav yaj nyob rau hauv ib qho kev muab cov kuab tshuaj ntawm qhov kub thiab txias. Muaj ob yam ncaj qha uas cuam tshuam rau kev solubility: kub thiab siab Kub cuam tshuam rau kev solubility ntawm cov khib nyiab thiab roj, tab sis lub siab tsuas cuam tshuam cov solubility ntawm gases.
4 yam uas cuam tshuam rau solubility yog dab tsi?
yam cuam tshuam rau solubility

Koj puas ntxiv cov kuab tshuaj rau cov kuab tshuaj?
Mov kom huv si kom yaj lub solute Thaum cov kuab tau yaj lawm, ntxiv cov kuab tshuaj uas tseem tshuav los ua cov tshuaj uas xav tau ntim thiab sib tov kom huv si. Piv txwv li, ua 0.5 Litres ntawm 0.5 molar NaCl: … Ua ib qho kev daws teeb meem ntawm ib qho concentration ntawm cov tshuaj hauv Tshuag yog hu ua dilution .
Thaum cov kuab tshuaj evaporates dab tsi tshwm sim rau qhov concentration ntawm cov tshuaj?
Qhov no txhais tau hais tias yog tias koj cov kuab tshuaj evaporating thiab qhov kub thiab txias tsis tu ncua, ces solute yuav precipitate tawm ntawm cov tshuaj. Qhov concentration ntawm cov tshuaj yuav tseem nyob rau ntawm nws qhov siab tshaj plaws raws li koj muaj kev txhawj xeeb nrog cov nyiaj solute yaj .
Cov qauv twg ntawm nephron reabsorbs cov tshuaj feem ntau?
Cov tubule sib thoojreabsorbs feem ntau cov tshuaj thiab tswj cov pH ntawm cov lim dej . Cov qauv twg ntawm nephron reabsorbs cov tshuaj feem ntau quizlet? Cov dej yuav ntws los ntawm cov hlab ntsha afferent mus rau hauv lub glomerulus, qhov twg nws yuav lim mus rau hauv glomerular capsule.
Qhov twg ntawm cov kuab tshuaj hauv qab no yog siv rau hauv kev sib txuas ntawm chlorofluorocarbon?
Dichloromethane yog ntau yam kev lag luam hnyav. Tus kws tshawb fawb Belgian Frédéric Swarts pioneer lub synthesis ntawm CFCs nyob rau hauv 1890s . CFCs ua li cas? CFCs thiab HCFCs feem ntau yog tsim los ntawm kev sib pauv halogen pib los ntawm chlorinated methanes thiab ethanesCov derivatives brominated yog tsim los ntawm cov tshuaj dawb-radical ntawm chlorofluorocarbons, hloov C-H daim ntawv cog lus nrog C- Br daim ntawv cog lus.
