Nrhiav cov pa roj carbon monoxide nrog plaub pawg sib txuas los txheeb xyuas cov chaw muaj peev xwm chiral. Kos koj cov molecule nrog wedges thiab dashes thiab kos ib daim iav duab ntawm lub molecule. Yog lub molecule nyob rau hauv daim iav duab yog tib molecule, nws yog achiral . Yog lawv yog txawv molecules, ces nws yog chiral.
Kuj paub yog, dab tsi yog ib qho achiral compound?
Lus txhais: Achiral . Ib qho molecule yog achiral yog tias nws yog superimposable ntawm nws daim iav duab. Feem ntau achiral molecules muaj ib lub dav hlau ntawm symmetry los yog ib qho chaw ntawm symmetry. Achiral molecules uas muaj stereocenter hu ua meso.
Tsis tas li ntawd, qhov txawv ntawm chiral thiab achiral molecules yog dab tsi? Achiral Cov khoom yog superimposable nrog lawv daim iav duab. Piv txwv li, ob daim ntawv yog achiral . Piv txwv li, chiral molecules , zoo li peb txhais tes, tsis yog superimposable daim iav duab ntawm ib leeg.
Tsis tas li ntawd, koj yuav ua li cas thiaj paub yog tias qhov sib xyaw ua ke yog Superimposable?
Qhov ncaj tshaj plaws txoj kev los txiav txim seb ib qho khoom muab yog chiral yog kos lossis pom qhov khoom ntawm daim iav duab thiab pom yog ob qho tib si (uas yog, superimposable ). Yog Cov khoom muaj ib lub dav hlau sab hauv ntawm symmetry ces nws yuav tsum yog achiral.
Dab tsi yog cov khoom chiral thiab achiral?
Chiral - piav ib khoom uas muaj cov cuab yeej ntawm tes; tus khoom yuav tsum tsis yog-superimposable ntawm nws daim iav duab. Achiral - piav ib khoom uas tsis muaj cov cuab yeej ntawm tes; tus khoom tuaj yeem superimposed ntawm nws daim iav duab.

Yuav ua li cas koj paub yog hais tias ib tug compound yog molecular?
Mixed Ionic / Molecular Compound Naming. Thaum naming cov tebchaw, thawj qhov uas koj yuav tsum tau ua yog txiav txim siab seb lub compound yog ionic lossis molecular. Saib cov ntsiab lus hauv qhov sib xyaw. * Ionic tebchaw yuav muaj ob qho tib si hlau thiab tsis yog hlau, los yog tsawg kawg yog ib tug polyatomic ion. * Molecular compounds yuav tsuas muaj cov hlau tsis muaj hlau
Yuav ua li cas koj paub yog hais tias ib tug diploid yog haploid?
Muaj ob hom hlwb hauv lub cev - cov hlwb haploid thiab cov hlwb diploid. Daim duab piv. Diploid Haploid Txog Diploid hlwb muaj ob pawg ua tiav (2n) ntawm chromosomes. Haploid hlwb muaj ib nrab ntawm cov chromosomes (n) raws li diploid - piv txwv li lub cell haploid tsuas muaj ib pawg chromosomes xwb
Yuav ua li cas koj paub yog hais tias ib tug txheej txheem yog spontaneous?
Los ntawm kev xav txog ob yam no, peb tuaj nrog Gibbs Free Energy sib npaug los kwv yees seb qhov kev cuam tshuam yuav tshwm sim li cas lossis tsis ua. Yog tias Gibbs Dawb Zog yog qhov tsis zoo, ces cov tshuaj tiv thaiv yog tshwm sim, thiab yog tias nws yog qhov zoo, ces nws tsis yog tshwm sim
Yuav ua li cas koj thiaj paub yog hais tias ib tug function tsis yog ib tug function?
Kev txiav txim siab seb qhov kev sib raug zoo yog qhov ua haujlwm ntawm daim duab yog qhov yooj yim los ntawm kev siv cov kab ntsug. Yog tias txoj kab ntsug hla qhov kev sib raug zoo ntawm daim duab ib zaug hauv txhua qhov chaw, qhov kev sib raug zoo yog qhov ua haujlwm. Txawm li cas los xij, yog tias txoj kab ntsug hla qhov kev sib raug ntau dua ib zaug, qhov kev sib raug zoo tsis muaj nuj nqi
Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
