Nrog rau qhov no peb yuav txiav txim siab tus naj npawb ntawm cov electrons hauv lub plhaub valence thiab nws cov qauv raws li txoj kev xav valence bond. Los ntawm cov lus piav qhia saum toj no peb tuaj yeem txiav txim siab tias khub ntawm isoelectronic thiab isostructural hom yog ClO−3, SO2−3.
Nyob rau hauv cov khub twg cov ions yog isoelectronic?
Option C) qhov kev xaiv no yog qhov tseeb raws li tus naj npawb ntawm electrons rau ob qho tib si sodium thiab oxygen yog tib yampiv txwv li 10. Yog li lawv yog khub isoelectronic.
Tus khub hauv qab no yog isoelectronic?
BrO-2 thiab BrF + 2 ions yog isoelectronic hauv xwm. Ob leeg muaj (35 + 17)=52 electrons.
Qhov twg hauv qab no tsis yog khub isoelectronic?
N-2(7+2=9)andO-2(8+2=10) ions tsis muaj cov lej ntawm electrons. Yog li N-2 thiab O-2 tsis yog khub isoelectronic.
Yog isostructural thiab isoelectronic?
Isoelectronic compounds yog cov tebchaw uas muaj cov khoom siv hluav taws xob zoo ib yam, lossis lwm yam lus muaj tib tus lej ntawm electrons. Ntawm qhov tod tes, isostructural compounds muaj tib lub qauv, hybridization thiab cov duab. … Yog li, lawv tsis yog isoelectronic.

Cov khoom xyaw twg hauv qab no ua cov tshuaj tsw qab hauv cov tshuaj txhuam hniav?
Sodium lauryl sulfate (SLS) yog surfactant feem ntau siv. YPuas yog tshuaj txhuam hniav puas yog surfactant? Surfactants. Ntau, txawm tias tsis yog tag nrho, tshuaj txhuam hniav muaj sodium lauryl sulfate (SLS) lossis lwm yam surfactants (detergents).
Ntawm qhov twg ntawm cov ces kaum hauv qab no yog cov haujlwm cosecant tsis tau txhais?
Qhov tseeb, tus nqi xa rov qab los ntawm kev ua haujlwm cosecant rau lub kaum sab xis ntawm xoom degrees lossis ib puas yim caum degrees yog suav tias yog tsis tau txhais, txij li qhov sib npaug csc (θ)= 1 / sin θ ) yuav suav nrog kev faib los ntawm xoom.
Ib qho ntawm cov hauv qab no yog cov piv txwv ntawm cov lus pom zoo rau huab cua?
Cov kws tshawb fawb tau paub txog ntau qhov kev tawm tswv yim zoo hauv kev nyab xeeb. Ib qho piv txwv yog melting ice. Vim tias cov dej khov muaj lub teeb-xim thiab muaj kev cuam tshuam, feem ntau ntawm cov hnub ci uas tsoo nws tau rov qab mus rau qhov chaw, uas txwv qhov kub ntawm qhov nws ua rau.
Qhov twg hauv qab no txiav txim siab txog cov luag haujlwm ntawm cov neeg muag khoom / tus nqi qis thiab cov neeg yuav khoom / tus neeg xauj tsev?
Cov luag haujlwm ntawm cov neeg muag khoom / tus neeg xauj tsev thiab cov neeg yuav khoom / tus neeg xauj tsev yog txiav txim siab los ntawm (1) nqe lus uas ob tog tau teev tseg hauv kev cog lus, (2) kev cai, thiab (3) cov cai teev tseg los ntawm Uniform Commercial Code (UCC).
Qhov twg yog qhov kev sib raug zoo ntawm stereochemical ntawm ob khub ntawm cov molecules?
Enantiomers thiab diastereomers tsuas yog ob qho kev sib raug zoo stereochemical uas koj tuaj yeem muaj ntawm ob lub molecules. Cov stereoisomers yog ob lub molecules uas ua tiav ob qhov kev xav tau hauv qab no: Ob lub molecules yuav tsum muaj tib lub qauv molecular, thiab.
