1. Ua ntej ntawm plaub lub atoms, lossis pawg ntawm atoms, txuas nrog rau chiral nruab nrab raws li tus naj npawb atomic ntawm lub atom uas yog sib txuas ncaj qha rau lub chiral chaw. Qhov siab dua tus lej atomic, qhov siab dua qhov tseem ceeb . "4" muaj qhov qis tshaj qhov tseem ceeb.
Kuj paub yog, koj ua li cas muab qhov tseem ceeb rau cov neeg hloov pauv?
Muab qhov tseem ceeb ua ntu zus rau plaub tus neeg hloov pauv los ntawm saib cov atoms txuas ncaj qha mus rau qhov chaw chiral
- Qhov siab dua tus naj npawb atomic ntawm tam sim no hloov pauv atom, qhov tseem ceeb dua.
- Yog tias ob tus neeg hloov pauv muaj tib lub atom tam sim ntawd,
Ib yam li ntawd, txoj cai tseem ceeb yog dab tsi? Txoj cai ua ntej muab cov lus qhia rau cov kab ke uas yuav tsum tau ua haujlwm. Cov txoj cai feem ntau koom nrog qhov kev xav tias kev teeb tsa txoj haujlwm thiab lub sijhawm tsis muaj kev ywj pheej. lub sijhawm ua haujlwm. Hauv kev siv qhov no txoj cai , lub sijhawm ua haujlwm thiab hnub kawg yog cov khoom tseem ceeb. ntawm cov ntaub ntawv.
Ua raws li qhov no, koj ua li cas muab qhov tseem ceeb hauv Runescape?
Ua ntej, txiav txim siab qhov twg ntawm cov chains muaj thawj qhov kev sib txuas rau ib qho atom nrog qhov siab tshaj plaws qhov tseem ceeb (tus lej atomic siab tshaj). Cov saw hlau ntawd muaj qhov siab dua qhov tseem ceeb . Yog tias cov saw hlau zoo sib xws, txuas mus rau cov saw hlau, kom txog rau thaum qhov sib txawv. Piv txwv li: ib qho ethyl substituent siv qhov tseem ceeb dhau ib qho kev hloov methyl.
Koj muab qhov tseem ceeb li cas?
Nyob rau hauv thiaj li yuav muab stereochemistry ntawm stereocenter lossis ob daim ntawv cog lus, lub qhov tseem ceeb , los yog qhov tseem ceeb, ntawm cov pab pawg uas txuas nrog lub stereocenter lossis ob daim ntawv cog lus yuav tsum tau txiav txim ua ntej. Ua ntej yog muab tus lej, nrog 1 yog qhov siab tshaj qhov tseem ceeb , 2 ua ntej, thiab lwm yam.

Yuav ua li cas koj nrhiav tau undefined qhov tseem ceeb nyob rau hauv rational expressions?
Ib qho lus qhia tsis meej yog tsis tau txhais thaum tus denominator sib npaug rau xoom. Txhawm rau nrhiav cov txiaj ntsig uas ua rau qhov kev qhia tsis meej, teeb tsa tus denominator sib npaug rau xoom thiab daws qhov kev sib npaug tshwm sim. Piv txwv li: 0 7 2 3 x x − Tsis tau txhais vim hais tias tus xoom yog nyob rau hauv tus denominator
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Vim li cas qhov adhesion ntawm dej yog qhov tseem ceeb rau lub neej?
Cov khoom nplaum ntawm cov dej tso cai rau cov dej tso cai rau cov dej molecules los lo rau cov dej uas tsis yog dej, uas ua rau qee qhov kev coj cwj pwm dej. Adhesion tso cai rau dej txav tawm tsam lub ntiajteb txawj nqus los ntawm cov nroj tsuag. Capillary nkaus vim yog adhesion tso cai rau cov ntshav txav los ntawm cov hlab ntsha me me hauv qee lub cev tsiaj
Vim li cas qhov chaw saum npoo rau qhov sib piv ntawm qhov tseem ceeb?
Qhov chaw rau qhov ntim qhov piv yog qhov tseem ceeb vim tias, raws li lub hnub nyoog ntawm tes thiab tsim cov khoom tseem ceeb xws li cov proteins nws loj tuaj. Cell tau loj dua, yog li nws qhov ntim tau loj dua, tab sis hmoov tsis zoo li ntim, thaj chaw ntawm lub xov tooj tsis tau loj dua sai
