Kev txiav txim siab: Lub molecular geometry ntawm BF3 yog trigonal planar nrog symmetric nqi tis ntawm lub hauv paus atom. Yog li ntawd BF3 yog nonpolar. Xav paub ntau ntxiv txog boron trifluoride ( BF3 ) ntawm wikipedia: Wikipedia Boron Trifluoride.
Kuj paub, yog bf3 polar lossis nonpolar?
A polar molecule tshwm sim los ntawm qhov sib npaug / tsis sib luag ntawm valence electrons. Txawm hais tias tej zaum yuav muaj kev sib faib tsis sib npaug ntawm cov khoom siv hluav taws xob hauv ib tus neeg daim ntawv cog lus, hauv a tsis muaj polar zoo li molecule BF3 cov nyiaj no sib npaug sib npaug thiab tshem tawm. Tsis muaj net dipole thiab cov BF3 yog tsis polar.
Kuj Paub, cov duab molecular cuam tshuam li cas rau polarity? Lub symmetrical puab thiab qhov tseeb tias cov polarities ntawm daim ntawv cog lus yog tib yam txhais tau hais tias cov polarities ntawm daim ntawv cog lus tshem tawm ib leeg tawm, tawm hauv molecule raws li tag nrho nonpolar. Ntau molecules yog nonpolar, tab sis muaj polar daim ntawv cog lus. Ib daim ntawv cog lus yog polar yog tias ob lub atom ntawm ob qho kawg yog qhov sib txawv.
Hais txog qhov no, dab tsi yog qhov molecular geometry ntawm bf3?
Trigonal Planar
Yog vim li cas bf3 muaj polar bonds?
hauv BF3 nyob ntawd yog tsis muaj ib khub ntawm electrons ntawm boron atom thiab tus kheej dipole lub sij hawm ntawm txhua txhua daim ntawv cog lus yog qhia los ntawm B rau F thaum nyob rau hauv rooj plaub ntawm NF3 muaj yog Ib khub ntawm electrons ntawm nitrogen atoms. Yog li DIPOLE MOMENT NTAWM LUB MOLECULE YOG Los ntawm NITROGEN mus rau ib leeg khub ntawm ELECTRONS thiab cov molecule yog polar.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
