Nrhiav tus txwv reagent los ntawm saib cov lej ntawm moles ntawm txhua tus reactant . Txiav txim siab qhov balancedchemical kev sib npaug rau cov tshuaj tiv thaiv. Hloov cov ntaub ntawv allgiven rau hauv moles (feem ntau yuav, los ntawm kev siv molarmass ua qhov hloov pauv). Xam cov mole piv los ntawm cov ntaub ntawv muab.

Yog li ntawd, dab tsi yog qhov limiting reactant nyob rau hauv ib qho kev sib npaug?

Limiting Reactant - Cov reactant nyob rau hauv achemical cov tshuaj tiv thaiv uas txwv tus nqi ntawm cov khoom uas yuav beformed. Cov tshuaj tiv thaiv yuav nres thaum tag nrho cov limitingreactant yog noj. Tshaj Reactant - Cov reactant nyob rau hauv ib qho tshuaj tiv thaiv uas tseem tshuav thaum muaj kev cuam tshuam thaum lub txwv reactant yog siv tag nrho.

Ib yam li ntawd, qhov limiting reactant hauv dej yog dab tsi? Cov pa oxygen (O2) tsim tsawg dej (H2O) tshaj hydrogen (H2Yog li ntawd, oxygen txwv reactant.

Ntawm no, dab tsi yog qhov txwv reagent piav qhia?

Cov txwv reagent (los yog txwv reactant los yog txwv tus neeg sawv cev) nyob rau hauv cov tshuaj tiv thaiv tshuaj yog cov tshuaj uas tau noj tag nrho thaum cov tshuaj tiv thaiv ua tiav. Cov khoom tsim tau raug txwv los ntawm qhov no. reagent , txij li cov tshuaj tiv thaiv tsis tuaj yeem txuas ntxiv yam tsis muaj nws.

Yuav ua li cas koj pom cov moles ntawm ib yam khoom ntawm ib tug limiting reactant?

Yog tias koj muab rau moles tam sim no ntawm txhua tus reactant , thiab hais kom nrhiav tus limitingreactant ntawm ib yam tshuaj tiv thaiv, ces txoj kev yooj yim tshaj rau nrhiav uas yog txwv yog los faib txhua tus nqi los ntawm cov khoom muaj feem cuam tshuam hauv qhov sib npaug (sib npaug) chemicalequation; qhov twg tus nqi tsawg tshaj plaws yog qhov limitingreactant.
