SeCl4 tau distorted trigonal pyramid geometry. Ntawm no, Se tsuas muaj ib khub ntawm electrons thiab yog li, nws yog sp3d hybridised.
Kuj paub, SeCl4 polar lossis nonpolar?
Yog lawm. Lub SeCl4 molecule yog polar vim hais tias ib leeg khub ntawm nonbonding electrons nyob rau hauv lub valence plhaub ntawm lub selenium atom interacts nrog lub bonding khub ntawm electrons, ua rau ib tug spatial asymmetry ntawm lub dipole lub sij hawm ntawm lub polar Se-Cl bonds. Qhov tshwm sim yog SeCl4 molecule nrog lub vas dipole sij.
Kuj Paub, SeCl6 yog dab tsi? Selenium Hexachloride SeCl6 Molecular Luj - EndMemo.
Nyob rau hauv kev hwm rau qhov no, daim ntawv cog lus lub kaum sab xis ntawm SeCl2 yog dab tsi?
cov khub ib leeg txo cov tetrahedral zoo tagnrho lub kaum sab xis ua 109.5o nruab nrab ntawm atoms los ntawm ob los yog plaub degrees, nyob ntawm seb tus neeg atoms sib koom ua ke.
Lewis qauv rau SeCl2 yog dab tsi?
Tshwj xeeb rau SeCl2 , tag nrho cov naj npawb ntawm valence electrons yog 6 (Se) + 2 * 7 (rau 2 Cl atoms) rau tag nrho ntawm 20. Raws li Se yog ob qho tib si txuas ntxiv thiab ntxiv mus rau sab laug ntawm lub sij hawm lub sij hawm piv rau Cl, nws yuav ua koj lub hauv paus atom. Kos lub qauv raws li Cl - Se - Cl hauv kab.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
