Ib txoj hauv kev los mus ua kom xam cov kev lag luam atom yog siv cov kauj ruam hauv qab no:
- Tsim ib qho tshuaj kev sib npaug rau qhov muab tshuaj tiv thaiv.
- Balance cov kev sib npaug .
- xam qhov loj ntawm reactants thiab cov khoom siv atomic masses thiab formula masses los ntawm lub periodic table.
- xam qhov feem pua atom kev lag luam .
Ib yam li ib tug yuav nug, Atom kev lag luam hauv ntsuab chemistry yog dab tsi?
Ntsuab Chemistry Txoj Cai: Atom Economy . Atom kev lag luam txhais tau hais tias ua kom muaj kev sib koom ua ke ntawm cov khoom siv los ntawm cov khoom pib lossis cov tshuaj reagents rau hauv cov khoom kawg. Nws yog qhov tseem ceeb tiv thaiv kev ua qias tuaj ntawm qib molecular.
Ib yam li ntawd, qhov sib npaug rau moles yog dab tsi? Piv txwv ua haujlwm: moles = mass ÷ molar loj (n=m/M) Xam cov pa oxygen, O2, nyob rau hauv moles tam sim no nyob rau hauv 124.5 g ntawm oxygen gas.
Xav txog qhov no, koj puas suav nrog coefficients hauv atom kev lag luam?
Atom kev lag luam txhais tau tias yog qhov quotient ntawm cov txheeb ze molecular loj ntawm cov khoom xav tau los ntawm cov txheeb ze molecular loj ntawm tag nrho cov reactants. Ib yam li ntawd, lwm yam coefficients nyob rau hauv chemical equation yuav yuav tsum tau coj mus rau hauv tus account.
Atom Economy yooj yim txhais yog dab tsi?
Atom kev lag luam ( atom efficiency / feem pua) yog kev hloov dua siab tshiab ntawm cov txheej txheem tshuaj nyob rau hauv tag nrho cov atoms koom nrog thiab cov khoom xav tau tsim.

Vim li cas kev lag luam tshuaj suav hais tias yog kev lag luam yooj yim?
Kev lag luam tshuaj siv cov khoom siv raw los tsim cov khoom lag luam qhia cov kua qaub, hauv paus, alkali thiab ntsev. Cov khoom siv feem ntau yog siv rau hauv kev tsim khoom ntawm lwm cov khoom lag luam xws li iav, chiv, roj hmab, tawv, ntawv thiab textiles. Yog li, peb tuaj yeem hais tias kev lag luam tshuaj lom neeg yog kev lag luam yooj yim
Vim li cas kev ntsuas thiab ntsuas qhov tseem ceeb hauv kev tshawb fawb txog kev lag luam?
Cov nplai tau siv ntau zaus hauv kev tshawb fawb kev lag luam vim tias lawv pab hloov cov ntaub ntawv zoo (xav, kev xav, kev xav) rau hauv cov ntaub ntawv ntau, cov lej uas tuaj yeem txheeb xyuas tau. Koj tsim ib qho kev ntsuas los ntawm kev muab cov khoom (yuav ua tau piav qhia) rau tus lej
Vim li cas thiaj muaj kev lag luam thiab kev ua lag luam?
Ua thiab lagging strands coli, DNA polymerase uas tswj feem ntau ntawm cov synthesis yog DNA polymerase III. Cov strand no yog ua tsis tu ncua, vim hais tias DNA polymerase yog txav mus rau tib qho kev taw qhia raws li cov diav rawg replication. Qhov no tsis tu ncua synthesized strand yog hu ua tus thawj strand
Dab tsi yog atom kev lag luam ntawm cov tshuaj tiv thaiv?
Lub atom kev lag luam ntawm cov tshuaj tiv thaiv yog ib qho kev ntsuas ntawm tus nqi ntawm cov khoom pib uas xaus li cov khoom muaj txiaj ntsig. Nws yog ib qho tseem ceeb rau kev txhim kho kom ruaj khov thiab yog vim li cas nyiaj txiag siv cov kev cuam tshuam nrog kev lag luam atom siab
Koj piav qhia txog daim duab hauv kev lag luam li cas?
Key Takeaways Ib daim duab qhia kev sib raug zoo ntawm ob lossis ntau qhov sib txawv. Ib qho kev nce-sloping nkhaus qhia txog kev sib raug zoo ntawm ob qhov sib txawv. Txoj kab nqes ntawm txoj kab nkhaus yog qhov piv ntawm txoj kab ntsug hloov mus rau kab rov tav hloov ntawm ob lub ntsiab lus ntawm qhov nkhaus
