Ntxiv mus, dab tsi yog qhov geometry ntawm ib lub molecule?
Molecular geometry yog cov duab 3-dimensional uas lub molecule nyob hauv qhov chaw. Nws yog txiav txim los ntawm lub hauv paus atom thiab cov atoms thiab electron ib puag ncig khub . Cov duab ntawm feem ntau cov molecules tuaj yeem kwv yees siv Valence Plhaub Electron Pair Repulsion (VSEPR) txoj kev.
Ib yam li ntawd, lub cev molecular ntawm No yog dab tsi? Lewis Structures thiab Shapes of Molecules
| Formula | Cov duab | |
|---|---|---|
| 14. | BF3 | trigonal txoj kev |
| 15. | TSIS MUAJ | kab tawm |
| 16. | PCl5 | trigonal bipyramidal |
| 17. | SF6 | octahedral |
Ib yam li ntawd, tib neeg nug, dab tsi yog qhov molecular geometry ntawm tef4?
TeF4 (SF4) muaj plaub daim ntawv cog lus thiab ib qho uas tsis yog cov khoom siv hluav taws xob, muab a trigonal pyramidal e- Domain geometry thiab pom sawt molecular geometry. Cov ces kaum sib txuas yog compressed txheeb ze tothose nyob rau hauv ib tug zoo meej trigonal bipyramid vim ib leeg khub kis tawm ntau nyob rau hauv qhov chaw tshaj li sib koom ua ke.
Dab tsi yog 5 cov duab yooj yim ntawm cov molecules?
Molecular Geometry. VSEPR txoj kev xav piav qhia tsib lub ntsiab ntawm cov qauv yooj yim: linear, trigonal planar, tetrahedral , trigonal bipyramidal, thiab octahedral.

Dab tsi yog qhov molecular geometry ntawm if4 -?
IF4 (iodine tetrafluoride) muaj octahedral electron geometry, tab sis cov molecular geometry hais tias cov atoms coj ib tug square planar duab. Qhov no yog vim iodine nqa ob leeg ib leeg, ib qho saum toj thiab hauv qab lub dav hlau ntawm x-axis
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
Dab tsi yog qhov molecular geometry thiab polarity ntawm bf3?
Kev txiav txim siab: Lub molecular geometry ntawm BF3 yog trigonal planar nrog symmetric nqi faib rau hauv nruab nrab atom. Yog li ntawd, BF3 yog nonpolar. Cov lus qhia ntxiv ntawm boron trifluoride (BF3) ntawm wikipedia: Wikipedia Boron Trifluoride
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
