coefficients yog tseem ceeb los ua pov thawj txoj cai ntawm kev txuag ntawm pawg. Cov coefficients nyob rau hauv ib tug balanced tshuaj kev sib npaug qhia cov txheeb ze ntawm moles ofreactants thiab cov khoom. Los ntawm cov ntaub ntawv no, lub Cheebtsam ntawm reactants thiab cov khoom yuav raug xam. Koj tuaj yeem txiav txim seb tus lej ntawm moles ntawm cov khoom.

Kuj paub, dab tsi yog qhov tseem ceeb ntawm cov coefficients hauv kev sib npaug tshuaj sib npaug?

Hauv ib balanced tshuaj sib npaug , tag nrho cov naj npawb ntawm 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 a chemicalequation . Cov no yog tseem ceeb vim lawv hais txog cov nyiaj ntawm cov reactants siv thiab cov khoom tsim.

Tsis tas li ntawd, vim li cas qhov sib npaug sib npaug tseem ceeb hauv stoichiometry? Coefficients ntawm a sib npaug tshuaj kev sib npaug qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Tag nrho stoichiometric suav pib nrog a kev sib npaug . Kev sib npaug yog qhov tsim nyog vim huab hwm coj tau khaws cia hauv txhua qhov tshuaj tiv thaiv. Qhov no yog cov reactant uas yog siv tag nrho hauv cov tshuaj tiv thaiv.

Ntawm no, cov coefficients nyob rau hauv ib qho kev sib npaug sib npaug sawv cev li cas?

First: lub coefficients muab tus naj npawb ntawm molecules (los yog atoms) koom nrog cov tshuaj tiv thaiv. Hauv kev ua piv txwv, ob lub molecules ntawm hydrogen react nrog ib lub molecule ntawm oxygen thiab tsim ob molecules ntawm dej. Thib ob: lub coefficients muab tus naj npawb ntawm moles ntawm txhua yam tshuaj muaj nyob rau hauv cov tshuaj tiv thaiv.

Dab tsi yog sawv cev los ntawm cov lej coefficients uas tau muab tso rau pem hauv ntej ntawm cov qauv hauv kev sib npaug sib npaug?

Muaj cov subscripts, uas yog ib feem ntawm cov tshuaj cov qauv ntawm cov reactants thiab cov khoom thiab muaj coefficients uas muab tso rau pem hauv ntej ntawm cov qauv Qhia seb muaj pes tsawg molecules ntawm cov khoom siv los yog tsim tawm. Daim duab 7.4.1: Sib npaug Kev sib npaug.
