Ntau Reactant txhais tau tias yog cov reactant nyob rau hauv cov tshuaj tiv thaiv tshuaj uas yog nyob rau hauv ntau thiab tseem unconsumed thaum cov tshuaj tiv thaiv nres vim lub limiting reactant limiting reactant Lub limiting reactant (los yog limiting reagent.) yog cov reactant uas tau noj thawj zaug hauv cov tshuaj tiv thaiv tshuaj thiab yog li txwv ntau npaum li cas cov khoom tuaj yeem tsim tau. https://www.khanacademy.org › science › ap-chemistry-beta

tau noj lawm.
Yuav ua li cas koj thiaj nrhiav tau qhov seem reactant?
Cov reactant uas tsim cov khoom loj dua yog cov reagent ntau dhau. Txhawm rau nrhiav cov nyiaj seem ntawm cov khoom siv ntxiv, rho tawm qhov loj ntawm cov reagent ntau dhau los ntawm tag nrho cov huab hwm coj ntawm cov reagent tau muab.
piv txwv ntawm stoichiometry yog dab tsi?
Stoichiometry yog thaj chaw ntawm chemistry uas cuam tshuam nrog cov txheeb ze ntawm cov tshuaj reactants thiab cov khoom lag luam hauv cov tshuaj tiv thaiv. … Piv txwv li, thaum oxygen thiab hydrogen react los tsim dej, ib mole ntawm oxygen reacts nrog ob moles ntawm hydrogen los tsim ob moles ntawm dej.
Dab tsi yog qhov ua rau ntau dhau?
Ib qho reactant ntau dhau yog ib qho reactant tam sim no nyob rau hauv ib qho nyiaj ntau tshaj qhov yuav tsum tau ua ke nrog tag nrho cov limiting reactant. Nws ua raws li cov reactant ntau dhau yog ib qho tseem tshuav nyob rau hauv cov tshuaj tiv thaiv sib tov ib zaug tag nrho cov limiting reactant tau noj.
Puas yog Potassium yog qhov txwv tsis pub rov ua dua?
Qhov siab tshaj plaws ntawm cov khoom yuav raug txiav txim los ntawm txwv reactant, piv txwv li cov reactant uas muab cov khoom tsawg kawg nkaus. Nyob rau hauv cov ntaub ntawv no, lub limiting reactant yog poov tshuaj carbonate, thiab lub siab tshaj plaws tawm los ntawm calcium carbonate yog 0.0125mol.
