Ci ntawm 180 degrees
Raws li txoj cai, lub kaum sab xis ntawm carbon monoxide yog dab tsi?
Lub zog ntawm repulsion ntawm cov electrons no tsawg kawg nkaus thaum ob C = O. ob npaug daim ntawv cog lus muab tso rau ntawm opposite sab ntawm lub carbon atom. VSEPR txoj kev xav yog li ntawd kwv yees li ntawd CO 2 yuav yog ib tug linear molecule, ib yam li BeF2,cu ib daim ntawv cog lus ntawm 180o.
Tsis tas li ntawd, yog co linear lossis bent? Khoov vs. Ob leeg yog txuas nrog ob pawg, yog li nws nyob ntawm seb muaj pes tsawg tus khub uas tsis yog khi rau lub hauv paus atom muaj. Ua tib zoo saib cov sulfur dioxide (SO2thiab carbon dioxide ( CO 2). Ob leeg muaj ob lub pa oxygen atom txuas nrog ob daim ntawv cog lus. Carbon dioxide yog kab tawm , thiab sulfur dioxide yog khoov.
Yog li ntawd, dab tsi yog qhov molecular geometry ntawm CO?
Nrog ob khub sib txuas ntawm lub hauv paus atom thiab tsis muaj ib leeg, cov molecular geometry ntawm CO 2 yog kab tawm (Daim duab 10.3. 3).
hybridization ntawm CO yog dab tsi?
hybridization ntawm carbon nyob rau hauv CO ( Cov pa roj carbon monoxide ) yog sp. Nws tuaj yeem nrhiav tau yooj yim los ntawm nws Lewis Structure, los ntawm kev ua tiav lawv cov octets. Muaj ib qho kev sib cog lus triple ntawm lawv nrog ib leeg ib khub ntawm txhua lub atom. Ua li no ob lub atoms muaj lawv cov octets tiav.

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
