Hauv qab no yog qee txoj hauv kev sib cais:
- Ntawv Chromatography. Qhov no txoj kev feem ntau yog siv hauv kev lag luam khoom noj.
- Lim. Qhov no yog qhov ntau dua txoj kev sib cais ib insoluble khov kho los ntawm a ua kua .
- Evaporation.
- Yooj yim distillation.
- Fractional distillation.
Raws li, 4 txoj hauv kev los cais qhov sib tov yog dab tsi?
Cov ntsiab lus
- Kev sib xyaw ua ke tuaj yeem sib cais siv ntau hom kev kawm.
- Chromatography suav nrog kev sib cais hnyav ntawm cov khoom nruab nrab.
- Distillation siv qhov zoo ntawm qhov sib txawv ntawm cov ntsiab lus kub.
- Evaporation tshem tawm cov kua los ntawm kev daws kom tawm hauv cov khoom siv.
- Lim cais cov khib nyiab ntawm qhov sib txawv.
Ib tug kuj yuav nug, dab tsi yog 10 txoj kev ntawm kev sib cais sib tov? Qee txoj hauv kev sib cais cov tshuaj los yog sib tov yog:
- Kev xaiv tes.
- Khaub ncaws.
- Winnowing.
- Sieving.
- Evaporation.
- Distillation.
- Lim los yog Sedimentation.
- Sib cais Funnel.
Hais txog qhov no, cov txheej txheem twg yog siv los cais cov khoom ntawm cov kua?
Lim
Dab tsi yog 7 txoj hauv kev los cais cov sib tov?
Txheeb xyuas txoj hauv kev xaiv tes, Threshing, Winnowing, Sieving, Sib nqus Attraction, Sublimation, Evaporation , Crystallization, Sedimentation & Decantation, Chaw thau khoom, Lim , Distillation , Centrifugation, thiab ntawv Chromatography tuaj yeem siv tau hauv lub neej txhua hnub.

Dab tsi yog lub tswv yim ntawm kev txhawb nqa ntawm kev sib cais ntawm kev sib deev?
Kev txhawb zog yog cov txheej txheem los ntawm kev xaiv ntuj tsim kom muaj kev sib cais ntawm kev sib deev. Kev txhawb zog tuaj yeem tshwm sim raws li hauv qab no: Thaum ob pawg neeg uas tau khaws cia sib nrug, rov qab los rau hauv kev sib cuag, qhov kev sib cais ntawm cov menyuam yaus yuav ua tiav lossis tsis tiav. Yog tias nws ua tiav, speciation tau tshwm sim
Dab tsi yog txoj kev ntawm kev sib cais sib tov?
Kev sib tov tuaj yeem sib cais siv ntau txoj kev sib cais xws li kev pom, sib cais funnel, sublimation, yooj yim distillation thiab ntawv chromatography. Cov txheej txheem tau hais los saum toj no yog txhua txoj kev siv lub cev
Puas yog qhov ceev yog ib txoj kev txhim khu kev qha ntawm kev txheeb xyuas tag nrho cov khoom tsis paub?
Koj tuaj yeem txheeb xyuas cov khoom tsis paub los ntawm kev ntsuas nws qhov ntom thiab sib piv koj cov txiaj ntsig rau cov npe paub qhov ntom ntom. Qhov ntom = loj / ntim. Xav tias koj yuav tsum txheeb xyuas cov hlau tsis paub. Koj tuaj yeem txiav txim siab qhov loj ntawm cov hlau ntawm qhov ntsuas
Qhov twg ntawm cov plaub hau plaub hau yog ib txwm plaub hau plaub hau?
square Tsis tas li ntawd nug, qhov ntsuas ntawm ib lub quadrilateral tsis tu ncua yog dab tsi? Yog, sab hauv lub kaum sab xis ntawm txhua lub ces kaum ntawm ib lub quadrilateral tsis tu ncua yog txhua 90 degrees (360 degrees / 4 fab).
Yuav siv txoj kev twg los cais cov khoom ntawm tus number case?
Chromatography yog ib txoj hauv kev los tshuaj xyuas cov khoom sib tov los ntawm kev sib cais rau hauv cov tshuaj uas lawv tau tsim. Nws tuaj yeem siv los cais cov khoom sib xyaw xws li tus cwj mem, ntshav, roj av, thiab daim di ncauj. Hauv ink chromatography, koj tab tom sib cais cov xim xim uas ua rau cov xim ntawm tus cwj mem
