Teb: PCl5 tsis ruaj khov vim phosphorus tsim 5 daim ntawv cog lus nrog cl atoms tawm ntawm ob daim ntawv cog lus muaj ntau qhov Bond ntev tshaj li peb qhov equatorial Bond ntev qhov no ua rau repulsion thiab yog li ntawd ua rau axial bonds tsis muaj zog.
Vim li cas PCl5 tsis ruaj khov dua PCl3?
PCl5 muaj cov duab pyramidal trigonal. Daim ntawv cog lus - daim ntawv cog lus khub rov qab ntau dua nyob rau hauv ob lub axial P-Cl daim ntawv cog lus piv rau peb txoj kab nruab nrab P-Cl daim ntawv cog lus. Vim li no, axial P-Cl daim ntawv cog lus yog tsis ruaj khovthiab raug tshem tawm yooj yim thaum PCl5 yog cua sov.
Vim li cas PCl5 thiaj li ua haujlwm?
Nyob hauv PCl5, ntxiv rau cov ntawv cog lus ncaj ncees uas nyob hauv tib lub dav hlau, muaj cov ntawv cog lus axial. Txij li thaum nws raug kev txom nyem ntau dua nws yog ntev dua li lwm cov ntawv cog lus. Tsis tas li ntawd cov no tsis muaj zog bondsand yog li cov nyiaj no tuaj yeem tawg tau yooj yim. Vim yog cov laj thawj no, PCl5 reactive heev.
Vim li cas PH5 tsis ruaj khov?
Qhia: Hydrogen tsawg dua electronegative dua li chlorine. Yog li, hydrogen tsis tuaj yeem sib koom ua ke thiab ua rau lub zog ntawm 3s atomic orbital ntawm phosphorus mus rau 3p atomic orbital. molecules, tsis muaj hybridization tshwm sim raws li Drago txoj cai. … molecule tsis ruaj khov thiab tsis muaj nyob.
Vim li cas PCl5 muaj tab sis tsis yog PH5?
Thaum PH5, P atom siv sp3d hybrid orbitals. Txij li thaum d orbital muaj zog dua s thiab p orbitals. … Tab sis vim qis electronegativity ntawm hydrogen, d orbital tsis tuaj yeem hybridised nrog s thiab p. Yog li sp3d hybridisationua tsis tau, Li no PH5 tsis muaj nyob thaum PCl5 ua tau.

Vim li cas emulsion tsis ruaj khov?
Emulsions yog cov tshuab thermodynamically tsis ruaj khov thiab nrawm nrawm rau hauv nyias txheej ntawm cov roj thiab dej [21]. Qhov no yog vim sib txawv ntawm cov roj thiab aqueous theem thiab kev sib cuag tsis zoo ntawm cov roj thiab dej molecules [
Puas muaj qhov chaw ruaj khov puas txhais tau tias tsis muaj zog nyob ruaj khov?
Thawj zaug nco ntsoov tias lub sijhawm kawg thib ob tsis suav tias yog lub ntsiab lus ntawm qhov muaj zog nyob ruaj khov, yog li, muaj zog ruaj khov tsis tas txhais tau tias tsis muaj zog nyob ruaj khov. Puas muaj zog nyob ruaj khov txhais tau tias tsis muaj zog nyob ruaj khov?
Vim li cas lub nplhaib beta lactam ntawm penicillin tsis ruaj khov?
Hydrolysis ntawm β-lactam nplhaib hauv penicillin ua rau nws tsis ua haujlwm. Hmoov tsis zoo, vim yog lub siab reactivity ntawm β-lactam nplhaib, ib penicillin tuaj yeem hnov mob nrog dej hauv cov kua qaub(raws li pom hauv plab), ua rau lub nplhaib β-lactam, hauv Cov tshuaj tiv thaiv hydrolysis.
Vim li cas ph meter nyeem tsis ruaj khov?
Thaum lub cev pH tsis ruaj khov, tsis zoo, lossis qhov kev sib tsoo, qhov teeb meem feem ntau yog ib qho hluav taws xob hauv av hauv qhov system, tshwj xeeb yog lub tank thiab / lossis cov kav dej. yog yas. Txhawm rau txheeb xyuas qhov teeb meem no, tshem tawm cov electrode thiab calibrate nws nyob rau hauv ib tug paub tsis nyob rau hauv lub beaker.
Vim li cas lub sijhawm tsis ruaj khov tsis zoo?
Qhov thib peb suav tias yog qhov tsis zoo tag nrho vim nws tuaj yeem ua chord loj lossis me, muab qhov sib txawv, zoo siab lossis tu siab. Thaum peb hnov Dunstable lub suab paj nruag niaj hnub no, nws suab zoo dua li kev hu nkauj thaum ub vim peb pob ntseg tau ua rau cov chords loj thiab me.
