Kuj Paub, vim li cas BeF2 covalent? Ua ntej tshaj plaws, txhua daim ntawv cog lus muaj ob qho tib si ionic thiab covalent tus cwj pwm. Qhov no piav qhia peb vim li cas BeF2 yuav tsum ionic. Tab sis txij li atomic loj ntawm beryllium me me heev, nws yuav muaj qhov ceev ceev & yuav pib rub lub electroncloud ntawm fluorine ntawm nws tus kheej. Yog li daim ntawv cog lus yuav dhau los ua polar covalent daim ntawv cog lus.
Tsis tas li ntawd, yog srf2 soluble hauv dej?
Cov khoom. Nws yuav luag insoluble hauv dej (nwsKsp tus nqi yog kwv yees li 2.0x10−10 ntawm 25 ° C).
Puas yog caf2 soluble hauv dej?
Feem ntau ntawm cov tebchaw hauv chav kawm no yog me ntsis soluble los yog insoluble nyob rau hauv dej . Yog soluble hauv dej , ces cov kev daws teeb meem feem ntau tsis muaj zog acidicnor xav tau yooj yim.
Pom zoo:
Vim li cas LiF tsis soluble hauv dej?
Vim nws cov dej tsis muaj zog thiab ib nrab covalent thiab ib nrab ionic cim LiCl yog soluble hauv dej thiab acetone. Hauv Lithium fluoride lub lattice enthalpy yog siab heev vim qhov me me ntawm fluoride ions. Hauv qhov no, hydration enthalpy yog tsawg heev. Yog li, LiF yog insoluble hauv dej
Vim li cas NaOH soluble hauv dej?
Raws li qhov tshwm sim, daim ntawv cog lus polarity yuav siab heev rau NaOH vim muaj kev ua haujlwm polarization, ua rau NaOH polarsolute. Yog li ntawd, mus los ntawm lub hauv paus ntsiab lus- "Likedissolves nyiam", polar NaOH yuav yooj yim dissolve nyob rau hauv polar H2O. Li no NaOH yuav solublein dej ntau heev thiab lwm yam polar solvents zoo li ethanol
Vim li cas phenol soluble hauv NaOH ntau dua li dej?
Phenol yog soluble hauv NaOH ntau dua hauv dej vim tias phenol yog acidic me ntsis. ua rau sodium phenoxide ntxiv ruaj khov. los tsim ib Hydronium ion (H30) phenol nrog sodium yog cov tshuaj tiv thaiv qeeb vim tias phenol yog cov kua qaub tsis muaj zog
Vim li cas cov dej hauv av silted suav hais tias yog lub cim ntawm kev tsim cov dab dej?
Sinkholes yog txhua yam hais txog dej. Dej yaj cov ntxhia hauv pob zeb, tawm hauv seem thiab qhib qhov chaw hauv pob zeb. Dej ntxuav cov av thiab cov seem ntawm cov voids hauv pob zeb. Kev txo qis ntawm cov dej hauv av tuaj yeem ua rau poob ntawm kev txhawb nqa rau cov khoom muag hauv cov pob zeb uas tuaj yeem ua rau tawg
Vim li cas HCl soluble hauv dej?
HCl yaj hauv dej (H2O). Cov hydrogenions (protons) hnov mob nrog dej los tsim hydronium ions (H3O) thiab cov chloride ions yog dawb hauv kev daws. H-Cl covalent bond ispolar. Nyob rau hauv ib tug polar daim ntawv cog lus cov electron khub sib koom ntawm ob atomsis attracted ntau dua electronegative atom
