Feem ntau hais lus, dej yog qhov zoo ntawm kev tawg ions thiab cov polar molecules, tab sis pluag ntawm cov khoom tsis muaj polar molecules. … (Ib tug polar molecule yog ib qho nruab nrab, los yog tsis muaj nqi, tab sis muaj ib qho asymmetric sab hauv kev faib tawm ntawm tus nqi, ua rau qee qhov zoo thiab qee qhov tsis zoo.)
Pob polarity yaj?
Yog cov polarities ntawm cov kuab tshuaj thiab solute match (ob qho tib si yog polar los yog ob qho tib si tsis muaj polar), ces tus solute yuav zaum dissolve. Yog tias cov polarities ntawm cov kuab tshuaj thiab cov kuab tshuaj sib txawv (ib qho yog polar, ib qho yog nonpolar), cov kuab tshuaj tej zaum yuav tsis yaj.
Pob polarity puas ua rau lawv soluble lossis insoluble hauv dej?
Yog li, polarity cuam tshuam rau solubility. Yog tias cov kuab tshuaj thiab cov kuab tshuaj muaj kwv yees li tib lub polarity, lawv yuav zaum tsim kev daws teeb meem. "Zoo li dissolves zoo li": Polar solutes yaj nyob rau hauv polar solvents; nonpolar solutes dissolves nyob rau hauv nonpolar solvents.
polar molecules yaj hauv dej li cas?
Yog li qhov tsis zoo ib feem ntawm ib qho polar molecule (xws li dej) yuav cuam tshuam nrog ib feem zoo ntawm lwm qhovmolecule (zoo li koj cov khoom tsis paub). Qhov no tso cai rau cov polar tshuaj yaj ib leeg. … Lawv tsis yog-polar, yog li muaj me me rau cov polar dej molecule yuav nyiam.
Yuav ua li cas thaum lub polar molecule muab tso rau hauv dej?
Raws li dej polarity, txhua dejmolecule attracts lwm cov dej molecules vim yog qhov opposite nqi ntawm lawv, tsim hydrogen bonds. Dej kuj nyiam, lossis nyiam, lwm cov polar molecules thiab ions, suav nrog ntau cov biomolecules, xws li qab zib, nucleic acids, thiab qee cov amino acids.

Ccl4 puas yuav yaj hauv dej?
Carbon tetrachloride, tseem paub los ntawm ntau lwm lub npe yog cov organic compound nrog cov tshuaj formula CCl₄. Nws yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw "qab zib" uas tuaj yeem kuaj pom ntawm qib qis. Nws yog xyaum tsis flammable ntawm qhov kub thiab txias.
Yuav tsum ionic compounds yaj hauv dej?
Ionic compounds yaj hauv dej yog tias lub zog muab tawm thaum cov ions cuam tshuam nrog cov dej molecules them rau lub zog xav tau los rhuav tshem cov ionic bonds hauv cov khoom thiab lub zog xav tau cais cov dej molecules kom cov ions tuaj yeem nkag mus rau hauv cov tshuaj.
Smarties puas yuav yaj hauv dej?
Peb pom cov Smarties siv sijhawm ntev dua li qhov xav tau; lawv yeej tawm ib teev kom yaj tag, tsis yog 5 feeb xwb. Puas Smarties yaj? Txheej ntawm Smarties yog ntau thinner txheej ntawm khoom qab zib. Qhov no tso cai rau lawv yaj hauv koj lub qhov ncauj yooj yim dua, thiab tsis tas yuav muaj crunching.
Yuav ua li cas disaccharides yaj hauv dej?
Txhua cov disaccharides yog dej soluble. Los ntawm kev tsim hydrogen bonds nrog lawv, dej dissolves disaccharides. … Vim muaj coob tus ntawm cov polar OH pawg, thaum yaj hauv dej, cov OH pawg no tsim hydrogen bonds nrog dej molecules. Hydrogen bonds nyiam cov dej molecules rau ib leeg.
Yuav cov dej khov puas yaj hauv lub tub yees?
Qhov kub hauv lub tub yees yog siab tshaj qhov khov, yog li cov dej khov yuav yaj. Nws siv sijhawm ntev heev txij li qhov ntsuas kub hauv lub tub yees yog nyob rau hauv qhov siab 30 (deg F) ntau. Cov huab cua los ntawm lub fridge tau yaj cov dej khov.
