Yog hais tias cov tshuaj sib npaug tsis sib npaug Tom qab ntawd nws ua txhaum txoj cai lij choj ntawm Kev Tiv Thaiv MASS uas tau muab los ntawm Antoine Lavoiser, nws hais tias tus naj npawb ntawm cov atoms nyob rau sab reactant yuav sib npaug rau cov lej ntawm cov atoms hauv cov khoom ntawm tib lub ntsiab lossis peb tuaj yeem hais tias cov atoms tsis tuaj yeem ua tsis tau. raug puas tsuaj los tsis tau

Yog li ntawd, tag nrho cov tshuaj sib npaug sib npaug?

Yuav siv tau, tshuaj sib npaug yuav tsum yog ib txwm sib npaug . Sib npaug tshuaj sib npaug muaj tib tus lej thiab hom ntawm txhua lub atom ntawm ob sab ntawm lub kev sib npaug . Cov coefficients hauv a kev sib npaug yuav tsum yog qhov yooj yim tag nrho tus lej piv. Mass yeej ib txwm khaws cia rau hauv tshuaj cov tshuaj tiv thaiv.

Ib yam li ntawd, kuv yuav ua li cas sib npaug tshuaj sib npaug? Rau tshuav nyiaj li cas a tshuaj sib npaug , pib los ntawm kev sau cov naj npawb ntawm cov atoms hauv txhua lub caij, uas tau teev nyob rau hauv subscript ntawm txhua lub atom. Tom qab ntawd, ntxiv coefficients rau cov atoms ntawm txhua sab ntawm lub kev sib npaug rau tshuav nyiaj li cas lawv nrog tib lub atoms ntawm lwm sab.

Ib yam li ntawd, tib neeg nug, vim li cas cov tshuaj sib npaug yuav tsum sib npaug?

A chemical equation yuav tsum sib npaug vim txoj cai tswj kev ruaj ntseg yuav tsum tuav zoo thaum lub sij hawm ib tshuaj sib npaug . Sib npaug ntawm kev sib npaug yog tsim nyog vim hais tias atoms tsis yog tsim los yog puas thaum lub sij hawm ib tshuaj sib npaug.

Tus lej nyob rau pem hauv ntej ntawm cov tshuaj formula hu ua dab tsi?

Coefficients yog cov tus lej hauv pem hauv ntej ntawm cov qauv . Ua ntej: cov coefficients muab cov tus lej ntawm molecules (los yog atoms) koom nrog cov tshuaj tiv thaiv. Hauv qhov piv txwv cov tshuaj tiv thaiv, ob lub molecules ntawm hydrogen react nrog ib molecule ntawm oxygen thiab tsim ob molecules ntawm dej.
