Qhov tseem ceeb . Feem pua tawm los yog tseem ceeb vim: tshuaj Cov tshuaj tiv thaiv feem ntau tsim los ntawm cov khoom lag luam nrog rau cov khoom npaj. Nyob rau hauv feem ntau cov tshuaj tiv thaiv, tsis yog tag nrho cov reactants yeej react.
Ntawm no, yield txhais li cas hauv chemistry?
Hauv chemistry , tawm los , kuj hu ua cov tshuaj tiv thaiv tawm los , yog cov tus nqi ntawm cov khoom tau txais hauv a tshuaj tshuaj tiv thaiv. Qhov tseeb tawm los tuaj yeem muab tau raws li qhov hnyav hauv grams lossis hauv moles (molar tawm los ).
Qhov thib ob, vim li cas qhov tseeb tawm los qis dua? Ib qhov tseeb tawm los yog qhov loj ntawm cov khoom tau txais los ntawm cov tshuaj tiv thaiv. Nws yog feem ntau tsawg tshaj qhov theoretical tawm los . Cov laj thawj rau qhov no suav nrog: cov tshuaj tiv thaiv tsis tiav, uas qee cov reactants tsis hnov mob los tsim cov khoom.
Ib yam li ib tug yuav nug, yog vim li cas feem pua yield tseem ceeb hauv kev lag luam kws tshuaj?
Cov qoob loo feem pua yog heev tseem ceeb hauv kev tsim khoom. Ntau lub sij hawm thiab nyiaj txiag yog siv los txhim kho lub feem pua yield rau kev tsim tshuaj lom neeg. Thaum cov tshuaj complex yog synthesized los ntawm ntau yam sib txawv, ib kauj ruam nrog ib tug tsawg feem pua yield tuaj yeem ua rau cov khoom pov tseg loj ntawm cov reactants sai sai thiab cov nqi tsis tsim nyog.
Dab tsi cuam tshuam rau feem pua yield?
Cov tawm los thiab tus nqi ntawm cov tshuaj tiv thaiv yog nyob ntawm tej yam kev mob xws li kub thiab siab. Qhov no yog ib qho teeb meem nyob rau hauv cov txheej txheem kev lag luam uas yuav tsum tau muaj siab feem pua yield . x 100. Ib feem pua yield txo yog tias cov reactants tsis ua tiav cov khoom.

Kev cog qoob loo yog dab tsi thiab vim li cas nws tseem ceeb?
Los piav qhia yooj yim, "grounding" txhais tau hais tias txoj kev tsis tshua muaj hluav taws xob tau tsim rau hluav taws xob mus rau hauv av. Yog tias muaj hluav taws xob hluav taws xob lossis hluav taws xob luv luv thaum koj siv cov khoom siv, muaj lub hauv paus hauv av los hloov cov tam sim no rau hauv lub ntiaj teb yuav tiv thaiv koj ntawm hluav taws xob poob siab
Dab tsi yog European pob kws borer thiab nws cuam tshuam li cas cov pob kws nroj tsuag thiab cov noob qoob loo?
Qhov kev puas tsuaj boring tuaj yeem ua rau cov nroj tsuag tsis muaj zog txaus los ua rau cov stalk tawg tom qab lub caij, feem ntau tshwm sim hauv qab pob ntseg. Los yog nws yuav ua rau pob kws ua stunted, ua rau cov qoob loo txo qis los ntawm cov nroj tsuag tsis muaj peev xwm thauj dej thiab cov as-ham los ntawm nws cov qia puas
Vim li cas peb thiaj siv cov lej tseem ceeb hauv chemistry?
Cov lej tseem ceeb (tseem hu ua tus lej tseem ceeb) yog ib feem tseem ceeb ntawm kev suav lej tshawb fawb thiab lej, thiab cuam tshuam nrog qhov raug thiab raug ntawm cov lej. Nws yog ib qho tseem ceeb rau kev kwv yees qhov tsis paub tseeb ntawm qhov kawg tshwm sim, thiab qhov no yog qhov tseem ceeb ntawm cov duab los ua qhov tseem ceeb heev
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
Tib neeg ua ntej hloov cov qoob loo li cas cov kws tshawb fawb siv niaj hnub no los hloov cov qoob loo?
Los ntawm cucumbers thiab carrots rau dawb nplej thiab nplej, peb tib neeg tau hloov cov noob ntawm yuav luag txhua yam zaub mov peb noj. Niaj hnub no cov kws tshawb fawb tuaj yeem tsim qhov kev hloov pauv sai sai los ntawm kev xaiv ib lub noob uas yuav ua rau muaj qhov xav tau thiab tso cov noob ncaj qha mus rau hauv chromosome ntawm lub cev
