Re: Vim li cas BH 2- thiab SnCl2 daim ntawv cog lus lub kaum sab xis <120? Teb: Ob leeg ntawm cov molecules muaj 3 cheeb tsam ntawm electron ceev: 2 kev sib raug zoo ib cheeb tsam thiab ib leeg ib khub.
Tsis tas li ntawd, cov duab ntawm sncl2 yog dab tsi?
Cov Cov duab ntawm Sncl2 yog V- zoo li tus vim yog ib leeg khub raws li VSPER txoj kev xav..
Tsis tas li ntawd, yog sncl2 polar lossis nonpolar? Txij li thaum Sncl2 tau khoov cov duab (muaj 1 khub ib leeg) nws dipole sij tsis sib npaug zero ua nws polar nyob rau hauv qhov.
Ua raws li qhov kev pom no, lub kaum sab xis ntawm cov pa roj carbon dioxide yog vim li cas?
Piav vim li cas Cov pa roj carbon dioxide muaj linear duab nrog a daim ntawv cog lus ntawm 180 degrees. Cov pa roj carbon dioxide muaj 1 carbon atom covalently bonded rau ob lub atoms oxygen. Cov pa roj carbon yog nyob rau hauv pawg 4 thiab yog li muaj 4 electrons nyob rau hauv nws lub plhaub sab nrauv.
Tus qauv ntawm SnCl2 yog dab tsi?
(stannous chloride) yog dawb crystalline khoom nrog cov qauv SnCl2. Nws tsim cov dihydrate ruaj khov, tab sis cov kev daws teeb meem aqueous zoo li yuav tsum tau siv hydrolysis, tshwj xeeb yog kub. SnCl2 yog dav siv los ua tus neeg sawv cev txo qis (hauv cov kua qaub), thiab hauv cov da dej electrolytic rau tin-plating.

Cov kab lus hloov sab hauv cov ces kaum piav qhia txoj haujlwm ntawm ob lub kaum sab xis li cas?
Hloov sab hauv cov ces kaum yog tsim los ntawm ib tug transversal intersecting ob parallel kab. Lawv nyob nruab nrab ntawm ob qho tib si kab tab sis nyob rau sab nraud ntawm lub transversal, tsim ob khub (plaub tag nrho cov ces kaum) ntawm cov ces kaum sab hauv. Hloov cov ces kaum sab hauv yog congruent, txhais tau tias lawv muaj qhov sib npaug
Koj tuaj yeem ua pov thawj li cas 2 daim duab peb sab zoo sib xws siv lub kaum sab xis sab SAS zoo sib xws postulate?
SAS Similarity Theorem hais tias yog ob sab hauv ib daim duab peb sab yog proportional rau ob sab hauv lwm daim duab peb sab thiab lub kaum sab xis nyob rau hauv ob qho tib si congruent, ces ob daim duab peb sab zoo ib yam. Ib qho kev hloov pauv zoo sib xws yog ib lossis ntau qhov kev hloov pauv tsis tu ncua ua raws li kev dilation
Dab tsi yog txoj cai kaum rau lwm lub kaum sab xis?
Hloov cov ces kaum sab hauv yog tsim thaum lub transversal hla dhau ob kab. Lub kaum sab xis uas tsim nyob rau sab nraud ntawm lub transversal thiab sab hauv ob kab yog alternate sab hauv cov ces kaum. Lub theorem hais tias thaum cov kab sib npaug, qhov sib txawv sab hauv cov ces kaum sib npaug
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
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
