Thaum tag nrho cov molecules yog attracted rau ib leeg, qee qhov chaw muaj zog dua lwm tus. Cov tsis-polar molecules yog attracted los ntawm ib London dispersion kev nyiam; polar molecules yog attracted los ntawm ob qho tib si London dispersion lub zog thiab lub zog dipole - dipole kev nyiam.
Tib neeg kuj nug, puas yog dipole dipole muaj zog dua London dispersion?
Tag nrho cov molecules, txawm polar los yog nonpolar, yog attracted rau ib leeg los ntawm London dispersion rog ntxiv rau lwm yam ntxim nyiam zog uas tej zaum yuav muaj. Feem ntau, txawm li cas los xij, dipole – dipole kev sib cuam tshuam hauv me me polar molecules yog qhov tseem ceeb muaj zog tshaj London dispersion rog , yog li tus qub predominate.
Tom qab ntawd, lo lus nug yog, dab tsi yog cov piv txwv ntawm London dispersion rog? Cov London dispersion rog no feem ntau pom nyob rau hauv halogens (piv txwv li, F2 thiab kuv2), cov noble cov pa (piv txwv li, Ne thiab Ar), thiab nyob rau hauv lwm yam uas tsis yog-polar molecules, xws li carbon dioxide thiab methane . London dispersion rog yog ib feem ntawm van der Waals rog, los yog tsis muaj zog intermolecular attractions.
Xav txog qhov no, dab tsi yog dipole dipole London dispersion?
Cov London dispersion quab yuam yog lub zog txaus nyiam ib ntus uas tshwm sim thaum cov hluav taws xob hauv ob lub atoms uas nyob ib sab tuav txoj haujlwm uas ua rau cov atoms tsim ib ntus. dipoles . Lub zog no qee zaum hu ua induced dipole -induced dipole kev nyiam.
Dab tsi yog qhov muaj zog tshaj plaws ntawm lub zog intermolecular?
hydrogen bonding

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
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
