~ Txawm tias nws muaj polar daim ntawv cog lus, methane yog a tsis muaj polar molecule vim nws cov duab tetrahedron tsis tu ncua ua rau muaj kev sib faib ntawm cov molecules ib nrab nqi. Raws li qhov tshwm sim, tsis muaj tus nqi xa tawm thoob plaws tag nrho cov molecule, uas ua rau methane a tsis yog - polar molecule.
Kuj tseem paub yog, vim li cas ch4 molecule nonpolar?
CH 4 yog tsis polar . Qhov sib txawv ntawm electronegativity ntawm carbon thiab hydrogen tsuas yog 0.4, yog li C-H bonds tsuas yog me ntsis polar. methane thiab lwm yam symmetrical kiag li molecules tsuas yog tsis polar nyob rau hauv kev sib cais, thiab los ntawm ib tug deb.
Vim li cas ch4 nonpolar thiab CH3Cl polar? Ob leeg CH 4 thiab CH 3 Cl muaj tetrahedral qauv tab sis CH 4 yog tsis polar thaum CH 3 Cl muaj polarity . Nws yog vim hais tias Cl (Chlorine) yog ib qho electronegative heev. Nws cov affinity siab rau electron tsim ib lub sij hawm dipole hauv C-Cl daim ntawv cog lus thiab li no net dipole yog ntawm C-Cl, ua rau nws. polar molecule.
Hauv qhov no, hom ntawv cog lus dab tsi yog methane yog polar lossis nonpolar?
Methane (CH4) yog a tsis polar hydrocarbon compound tsim tawm ntawm ib qho carbon atom thiab 4 hydrogen atoms. Methane yog tsis polar raws li qhov sib txawv hauv electronegativities ntawm carbon thiab hydrogen tsis zoo txaus rau daim ntawv polarized tshuaj daim ntawv cog lus.
Dab tsi yog tag nrho polarity ntawm methane?
Raws li peb tau pom, C-H daim ntawv cog lus hauv methane yog polar . Txawm li cas los xij, ib qho molecule ntawm methane tsis yog- polar . Tshwj xeeb, lub sijhawm dipole ntawm methane yog zero. Lub sijhawm dipole ntawm xoom txhais tau hais tias "qhov nruab nrab ntawm qhov tsis zoo" hauv cov molecule sib raug rau "qhov chaw ntawm qhov zoo".

Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
Vim li cas lub cube cag ntawm tus lej tsis zoo yog tus lej tsis zoo?
Tus lej tsis zoo lub voos xwmfab hauv paus yuav tsis zoo Txij li qhov ntsuas tus lej txhais tau tias tsa nws mus rau lub zog thib 3 - uas yog khib - lub voos xwmfab ntawm cov lej tsis zoo yuav tsum yog qhov tsis zoo. Thaum lub qhov hluav taws xob tawm (xiav), qhov tshwm sim tsis zoo. Thaum lub qhov hluav taws xob qhib (daj), qhov tshwm sim yog qhov zoo
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Puas yog acetonitrile polar lossis tsis polar?
Acetonitrile muaj 5.8 polarity index.Hydrocarbons tsis-polar yog li lawv yog cov kuab tshuaj tsuas yog rau lwm yam tshuaj tsis-polar. Tsis zoo li hydrocarbons, Ethyl Cawv muaj ob pawg polar thiab non-polarchemical ntawm cov molecule
