Nrhiav qhov txwv reagent los ntawm kev xam thiab sib piv cov khoom ntawm txhua reactant yuav tsim

1. Sib npaug cov tshuaj sib npaug rau cov tshuaj tiv thaiv.
2. Hloov cov ntaub ntawv muab rau hauv moles.
3. Siv stoichiometry rau txhua tus neeg reactant mus nrhiav tau pawg ntawm cov khoom tsim.

Yog li ntawd, qhov feem pua yuav tau tshaj 100 piav qhia?

Feem ntau, feem pua yields yog nkag siab tsawg dua 100 % vim yog vim li cas qhia ua ntej. Txawm li cas los xij, feem pua yields ntau dua 100 % yog ua tau yog tias cov khoom ntsuas ntawm cov tshuaj tiv thaiv muaj impurities uas ua rau nws loj loj dua nws ua tau yuav yuav yog hais tias cov khoom yog dawb huv.

Kuj Paub, dab tsi yog ib qho piv txwv txwv reactant? Limiting Reactant - Cov reactant nyob rau hauv ib qho tshuaj tiv thaiv uas txwv tus nqi ntawm cov khoom uas tuaj yeem tsim. Cov tshuaj tiv thaiv yuav nres thaum tag nrho cov txwv reactant yog noj. Tshaj Reactant - Cov reactant nyob rau hauv ib qho tshuaj tiv thaiv uas tseem tshuav thaum cov tshuaj tiv thaiv nres thaum lub txwv reactant yog noj tag.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov txwv reagent piav qhia nrog piv txwv?

Limiting reagent :-Nws yog txhais raws li ib yam khoom, uas tau noj tag nrho thaum cov tshuaj tiv thaiv tiav. Thiab cov khoom tsim, yog txwv los ntawm qhov no reagent , thiab cov tshuaj tiv thaiv tsis tau yog tsis muaj txwv reagent . RAU EXAMPLE :- C+O----CO. 1 mol + 1 mol ---- 1 mol.

Koj txiav txim siab li cas feem pua yield?

Txhawm rau qhia qhov ua tau zoo ntawm cov tshuaj tiv thaiv, koj tuaj yeem suav cov feem pua yield siv cov qauv no: % tawm los = (ua tawm los / theoretical tawm los ) x 100. A feem pua yield ntawm 90% txhais tau hais tias cov tshuaj tiv thaiv yog 90% ua tau zoo, thiab 10% ntawm cov ntaub ntawv tau nkim (lawv ua tsis tau tejyam, lossis lawv cov khoom tsis raug ntes).
