Txhais. Van der Waals rog muaj xws li attraction thiab repulsions ntawm atoms, molecules, thiab nto, nrog rau lwm yam intermolecular zog . Lawv txawv ntawm covalent thiab ionic bonding nyob rau hauv uas lawv yog tshwm sim los ntawm correlations nyob rau hauv lub fluctuating polarizations nyob ze hais (ib tug tshwm sim ntawm quantum dynamics).
Yog li ntawd, Van der Waals rog nyob qhov twg?
Zoo, Van der Waals rog yog tam sim no nyob rau hauv tag nrho cov kev sib cuam tshuam ntawm covalent molecules thiab non-metals. Raws li kev ceeb toom, tej zaum koj tau hnov txog li cas cov dej molecules cuam tshuam los ntawm qhov muaj zog heev Van Der Waals , hydrogen bonding.
Ib yam li ntawd, dab tsi yog van der Waals rog hauv chemistry? Van der Waals rog ' yog ib lo lus dav dav siv los txhais qhov attraction ntawm intermolecular zog nruab nrab ntawm molecules. Muaj ob hom Van der Waals rog : qaug zog London Dispersion Kev quab yuam thiab muaj zog dipole-dipole zog.
Ua raws li qhov no, ua li cas van der Waals rog suav?
Van der Waals Equation V hauv qauv hais txog qhov ntim ntawm cov pa, hauv moles n. Intermolecular zog ntawm attraction yog incorporated rau hauv lub kev sib npaug nrog n 2 a V 2 frac{n^2a}{V^2} V2n2a? lub sij hawm qhov twg a a yog tus nqi tshwj xeeb ntawm ib qho roj.
Dab tsi yog peb hom van der Waals rog?
Peb hom van der Waals muaj xws li: 1) dispersion (tsis muaj zog), 2) dipole - dipole (nruab nrab), thiab 3) hydrogen (muaj zog). Ion- dipole bonds (Ionic hom rau covalent molecules) yog tsim ntawm ions thiab polar molecules.
Pom zoo:
Dab tsi universal rog yog qhov ua tau zoo tshaj plaws nyob rau qhov ntev?
Lub ntiajteb txawj nqus yog lub zog tsis muaj zog tshaj plaws thoob ntiaj teb, tab sis nws yog lub zog zoo tshaj plaws nyob rau qhov ntev
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov kub ntawm qhov twg catalase enzyme ua haujlwm ntawm nws qhov zoo tshaj plaws?
Yog lawm, catalase ua haujlwm zoo tshaj plaws ntawm qhov nruab nrab pH thiab kub ntawm 40 ° C, ob qho tib si ze rau cov ntaub so ntswg ntawm tus tsiaj
Lub xeev twg ntawm cov teeb meem twg muaj zog tshaj intermolecular rog ntawm attraction?
Raws li qhov kub thiab txias tseem poob qis, qhov teeb meem tsim muaj zog. Vim tias cov khoom tsis muaj zog kinetic, cov khoom tsis muaj 'lub sij hawm' txav mus los, cov khoom muaj 'lub sij hawm' kom nyiam. Yog li ntawd, cov khib nyiab muaj qhov muaj zog tshaj plaws intramolecular rog (vim lawv muaj qhov muaj zog tshaj plaws)
Dab tsi yog qhov ua haujlwm ntawm Tfiih hauv qhov kev hloov pauv pib ua haujlwm?
(NER)TFIIH yog qhov kev hloov pauv dav dav uas ua haujlwm los nrhiav RNA Pol II rau cov neeg txhawb nqa ntawm cov noob. Nws ua haujlwm raws li lub helicase uas unwinds DNA. Nws kuj tseem tshem tawm DNA tom qab qhov mob DNA tau lees paub los ntawm txoj kev kho genome thoob ntiaj teb (GGR) lossis txoj kev hloov pauv-coupled kho (TCR) txoj hauv kev ntawm NER
