Tus coefficient hauv cov tshuaj formula yog tus lej tam sim ua ntej qhov sib xyaw. Nws zoo nkaus li qhov loj me, tsis txhob ua tus ntawv sau lossis tus sau ntawv.

Tus coefficient siv rau dab tsi?

Ua ntej: cov coefficients muab cov lej ntawm cov 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. Thib ob: cov coefficients muab tus naj npawb ntawm moles ntawm txhua yam tshuaj koom nrog hauv cov tshuaj tiv thaiv.
