Qab Zib yaj hauv dej vim hais tias lub zog yog muab tawm thaum lub me ntsis polar sucrose molecules tsim intermolecular bonds nrog polar dej molecules. Nyob rau hauv cov ntaub ntawv ntawm qab zib thiab dej Cov txheej txheem no ua haujlwm zoo heev uas mus txog 1800 grams sucrose tuaj yeem yaj hauv ib liter ntawm dej.
Ib yam li ntawd, tib neeg nug, ua li cas qab zib soluble hauv dej?
Kev sib txuas ntawm cov pa oxygen thiab hydrogen atoms (O-H bond) hauv qab zib (sucrose) muab cov pa oxygen me ntsis tsis zoo thiab cov hydrogen ib qho zoo me ntsis. Qhov polar dej molecules nyiam qhov tsis zoo thiab qhov zoo ntawm cov polar sucrose molecules uas ua rau sucrose yaj hauv dej.
Ib yam li ntawd, qab zib yaj hauv dej hu ua dab tsi? Ib tug solute yog cov khoom-xws li cov khoom, kua los yog gas-uas tau txais yaj . Hom kua tshuaj no yog tsim los ntawm cov kuab tshuaj, uas yog cov qab zib , thiab kua kuab tshuaj, uas yog dej . Raws li cov qab zib molecules kis tusyees thoob plaws hauv lub dej , cov qab zib yaj.
Yog li ntawd, vim li cas cov piam thaj yooj yim yaj hauv dej?
A Dej -soluble qab zib Yog vim li cas qabzib dissolves yooj yim hauv dej yog vim nws muaj ntau pawg polar hydroxyl uas muaj peev xwm hydrogen-bond nrog dej molecules. Hydrogen bonds yog ib qho tseem ceeb heev intermolecular rog uas txiav txim siab cov duab ntawm molecules zoo li DNA, proteins thiab cellulose.
Yuav ua li cas thaum koj sib tov qab zib thiab dej?
Cov crystals uas tsim cov qab zib , thaum ua ke nrog cov kub dej , tau yaj. Thaum tshav kub kub dej ua rau cov crystals tawg ua tej daim me me uas lawv "poob lawm." Peb tsis pom qhov qab zib lawm vim cov dej molecules tau khi rau lub qab zib molecules.

Puas yog kev sib xyaw cov khoom xyaw rau lub ncuav mog qab zib yog tshuaj lom neeg?
Cov ntaub ntawv yooj yim ntawm kev sib cais thiab sib xyaw yog suav tias yog kev hloov pauv ntawm lub cev, tab sis kev sib xyaw cov khoom xyaw ntawm lub ncuav mog qab zib tsis yog ib qho kev sib xyaw yooj yim. Kev hloov tshuaj pib tshwm sim thaum cov khoom xyaw sib xyaw, tsim cov tshuaj tshiab
Dab tsi tshwm sim thaum qab zib thiab ntsev sib tov hauv dej?
Thaum koj dissolve qab zib los yog ntsev hauv aliquid-hais, dej-dab tsi tshwm sim yog tias cov piam thaj molecules txav kom haum lawv tus kheej ntawm lawv cov dej hauv ib khob los yog beaker. Ib qho kuab tshuaj, xws li qab zib, yaj hauv cov kuab tshuaj, xws li dej, ua rau cov kua ua kua
Puas yuav loj hloov thaum qab zib yaj hauv dej?
Puas yog qhov loj ntawm cov piam thaj hloov thaum nws yaj hauv cov kua? Nyob rau hauv tag nrho cov tshuaj, thiab feem ntau cov tshuaj tiv thaiv lub cev, kev txuag ntawm huab hwm coj yog pom. Thiab qhov no txhais tau tias. Thiab yog li yog tias peb yaj cov piam thaj ntau hauv cov dej, qhov loj ntawm cov tshuaj yuav yog PRECISELY
Puas yog dej qab zib homogeneous lossis heterogeneous?
Cov dej qab zib-dej yog homogeneous sib xyaw thaum cov xuab zeb-dej yog qhov sib xyaw heterogeneous. Ob leeg yog cov sib tov, tab sis tsuas yog cov suab thaj-dej tuaj yeem hu ua kev daws teeb meem
Cov khoom qab zib yaj hauv dej li cas?
Qab Zib yaj nyob rau hauv dej vim hais tias lub zog yog muab tawm thaum lub me ntsis polar sucrose molecules tsim intermolecular bonds nrog polar dej molecules. Cov ntawv cog lus tsis muaj zog uas tsim los ntawm cov kuab tshuaj thiab cov kuab tshuaj tau them nyiaj rau lub zog xav tau los cuam tshuam cov qauv ntawm ob qho tib si ntshiab solute thiab hnyav
