Thaum twg koj tshuav ib kev sib npaug koj tsuas hloov tau coefficients (tus lej nyob rau hauv pem hauv ntej ntawm molecules los yog atoms). Coefficients yog cov lej nyob rau hauv 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 !

Raws li, qhov twg yog tib qho uas tuaj yeem hloov pauv tau thaum koj sib npaug ntawm qhov sib npaug ntawm lub cev?

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

Qhov thib ob, thaum ntsuas cov tshuaj tiv thaiv kab mob ntau npaum li cas peb hloov kho? Thaum twg koj hloov cov coefficients, koj ' tsuas yog hloov cov tus lej ntawm cov molecules ntawm cov khoom tshwj xeeb. Txawm li cas los xij, thaum koj hloov cov subscripts, koj hloov cov khoom nws tus kheej, uas yuav ua rau koj tshuaj sib npaug yuam kev.

Tsis tas li cov lus nug yog, vim li cas koj thiaj li hloov tsis tau cov mis kom sib npaug ntawm cov tshuaj tiv thaiv?

Koj ua tsis tau hloov subscripts hauv tshuaj qauv rau tshuav nyiaj li cas ib qho tshuaj kev sib npaug ; koj ua tau hloov tsuas yog cov coefficients. Hloov subscripts hloov qhov ratios ntawm atoms nyob rau hauv lub molecule thiab lub resulting tshuaj zog. Piv txwv li, dej (H2O) thiab hydrogen peroxide (H2O2) yog cov tshuaj sib txawv.

Qhov twg hauv qab no tsis tuaj yeem ua tiav thaum ntsuas qhov sib npaug tshuaj?

Thaum twg balancing ib chemical equation , koj yeej tsis tau hloov subscripts ntawm ib qho twg tshuaj formula . e. Hauv tshuaj tshuaj tiv thaiv, teeb meem yog tsis tsim los yog rhuav tshem li ntawd a chemical equation yuav tsum muaj pes tsawg tus atoms ntawm ob sab ntawm lub kev sib npaug.
