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.
