Thaum twg koj hloov tus coefficients , koj ' tsuas yog hloov tus naj npawb ntawm cov molecules ntawm cov khoom tshwj xeeb. Txawm li cas los xij, thaum koj hloov tus subscripts , koj yog hloov cov khoom nws tus kheej, uas yuav ua koj tshuaj sib npaug yuam kev.

Ib yam li ntawd, vim li cas cov ntawv sau tsis tuaj yeem hloov pauv thaum ntsuas qhov sib npaug tshuaj?

Tsuas yog cov coefficients tuaj yeem ua tau hloov nyob rau hauv thiaj li yuav balance ib chemical equation . Subscripts yog ib feem ntawm cov tshuaj formula rau reactants los yog khoom thiab ua tsis tau ua hloov rau tshuav nyiaj li cas ib kev sib npaug . Hloov ib subscript hloov cov khoom sawv cev los ntawm cov qauv.

Tsis tas li, vim li cas cov coefficients siv los sib npaug sib npaug? Hauv ib sib npaug tshuaj kev sib npaug , tag nrho cov atoms ntawm txhua lub caij tam sim no yog tib yam ntawm ob sab ntawm lub kev sib npaug . Stoichiometric coefficients yog cov coefficients yuav tsum tau tshuav nyiaj li cas ib qho tshuaj kev sib npaug . Cov no yog qhov tseem ceeb vim lawv txheeb cov nqi ntawm cov reactants siv thiab cov khoom tsim.

Kuj tseem xav paub, vim li cas nws tseem ceeb kom txo cov coefficients hauv qhov sib npaug sib npaug kom qis tshaj qhov ua tau?

Teb yog: nws yog tseem ceeb vim hais tias nyob rau hauv txoj kev chemist yuav pom qis tshaj tau tus naj npawb ntawm reactants hauv tshuaj cov tshuaj tiv thaiv xav tau los tsim cov khoom ntawm cov tshuaj tiv thaiv. Coefficients nrog rau qis tshaj ratio qhia qhov txheeb ze ntawm cov tshuaj hauv cov tshuaj tiv thaiv.

Dab tsi tuaj yeem hloov kho thaum ntsuas tshuaj sib npaug?

Thaum koj tshuav nyiaj li cas ib kev sib npaug koj ua tau tsuas yog hloov cov coefficients (tus lej nyob rau hauv pem hauv ntej ntawm molecules los yog atoms). Coefficients yog cov lej nyob rau pem hauv ntej ntawm lub molecule. Subscripts yog cov lej me dua tom qab atoms. Cov no ua tsis tau hloov thaum sib npaug tshuaj sib npaug !
