Van der Waals rog' yog ib lo lus dav dav siv los txhais qhov attraction ntawm intermolecular rog ntawm molecules. Muaj ob hom Van der Waals rog: Tsis muaj zog London Dispersion Forces thiab muaj zog dipole-dipole rog.
Tom qab ntawd, dab tsi yog piv txwv ntawm van der Waals force?
Van der Waals rog yog cov tsis muaj zog zog uas ua rau muaj kev sib txuas ntawm kev sib txuas ntawm cov molecules. Piv txwv ntawm van der Waals rog muaj xws li hydrogen bonding, dispersion zog , thiab dipole-dipole kev sib cuam tshuam.
Qhov thib ob, Van der Waals rog suav li cas? 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 kev sib npaug nrog n 2 a V 2 frac{n^2a}{V^2} V2n2a? lub sij hawm uas a a yog tus nqi tshwj xeeb ntawm ib qho roj.
Ib yam li ntawd, dab tsi ua rau van der Waals rog?
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 ua rau los ntawm correlations nyob rau hauv lub fluctuating polarizations ntawm ze particles (ib tug tshwm sim ntawm quantum dynamics).
Vim li cas van der Waals thiaj li qaug zog?
Van der Waals rog tseem hu ua London Dispersion Kev quab yuam yog qaug zog raws li lawv yog qhov ua rau lub sijhawm dipole txav hauv cov atoms. Nws yog ib qho tseem ceeb nyob rau hauv noble gases.

Nyob rau hauv chemistry, ib pab pawg (tseem hu ua tsev neeg) yog ib kem ntawm cov ntsiab lus nyob rau hauv lub sij hawm lub sij hawm ntawm cov tshuaj. Muaj 18 pawg lej nyob rau hauv daim ntawv teev sijhawm; cov kab f-block (nruab nrab ntawm pawg 3 thiab 4) tsis suav nrog
Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog txhais los ntawm lo lus inorganic hauv lub ntsiab lus ntawm cov ntxhia?
Ib txwm tshwm sim, homogeneous inorganic khoom muaj cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv crystalline qauv, xim, thiab hardness. Ib qho khoom siv tsis zoo, xws li calcium, hlau, potassium, sodium, lossis zinc, uas yog qhov tseem ceeb rau kev noj haus ntawm tib neeg, tsiaj txhu, thiab nroj tsuag
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Lub npe ntawm tag nrho cov ntsiab lus ntawm lub sij hawm lub rooj yog dab tsi?
