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.

Qhov tseem ceeb tshaj plaws, qhov tseem ceeb tshaj plaws yuav ua rau koj ntseeg siab hais tias "tsis yog." Lawv pab koj txheeb xyuas qhov xav tau tiag tiag hauv koj lub neej, piv rau lwm tus xav tias tseem ceeb.
Daim npav tsis muaj nyiaj tsis muaj nyiaj siv tau nyob qhov twg?
Daim Npav Tsis Muaj Nyiaj Txiag yuav ua haujlwm ntawm cov tub lag luam uas lees txais Visa lossis eftpos, suav nrog txawv teb chaws. Tib lub sijhawm siv daim npav tsis tuaj yeem yog rau kev yuav cawv, khoom twv txiaj, daim npav zoo li nyiaj ntsuab lossis rho nyiaj ntsuab.
Vim li cas qhov tseem ceeb ntawm qhov muaj zog thiab qhov tsis muaj zog yog qhov tseem ceeb?
Nws yog ib qho tseem ceeb rau qhov tseem ceeb ntawm qhov ua tau zoo thiab qhov tsis muaj zog vim qhov no pab lub tuam txhab txiav txim siab txog thaj chaw uas lawv yuav tsum tau txhim kho ntxiv rau thaj chaw uas lawv ua tau zoo hauv. Vim li cas lub zog thiab qhov tsis muaj zog tseem ceeb?
