A mole ratio yog ib qho kev hloov pauv uas cuam tshuam cov nyiaj hauv moles ntawm ob yam khoom nyob rau hauv ib qho tshuaj tiv thaiv. Cov lej hauv ib qho kev hloov pauv yog los ntawm cov coefficients ntawm qhov sib npaug tshuaj sib npaug. Cov nram qab no rau mole ratios tuaj yeem sau rau ammonia tsim cov tshuaj tiv thaiv saum toj no.
Yog li ntawd, koj yuav nrhiav tau tus mole ratio li cas?
- Pib nrog tus naj npawb ntawm grams ntawm txhua lub caij, muab rau hauv qhov teeb meem.
- Hloov cov huab hwm coj ntawm txhua lub caij mus rau moles siv cov molar loj los ntawm lub sijhawm teem sijhawm.
- Faib txhua tus nqi mole los ntawm tus lej tsawg tshaj plaws ntawm moles suav.
- Hloov mus rau tus lej uas nyob ze tshaj plaws. Qhov no yog qhov piv ntawm mole ntawm lub ntsiab thiab yog.
Tsis tas li ntawd, vim li cas mole ratio tseem ceeb? Mole ratios yog tseem ceeb vim mole ratios tso cai rau koj hloov moles ntawm ib yam khoom rau moles ntawm lwm yam khoom. Cov mole ratio yog cov khawv koob uas hloov ntawm A mus rau B. Tus mole ratios los ntawm cov tshuaj formula los yog sib npaug.
mole ratio yog dab tsi?
tus piv nruab nrab ntawm cov nyiaj hauv moles ntawm ob lub tebchaw koom nrog hauv cov tshuaj tiv thaiv tshuaj. Mole ratios yog siv los ua kev hloov pauv ntawm cov khoom thiab cov tshuaj reactants hauv ntau cov teeb meem chemistry.
Mole conversion yog dab tsi?
Hloov pauv los ntawm moles rau ntim (litres): Ua kom koj ntau mole tus nqi los ntawm molar ntim tas li, 22.4L. Hloov pauv los ntawm cov khoom (atoms, molecules, los yog formula units) mus rau moles : Faib koj tus nqi particle los ntawm Avogadro tus lej, 6.02 × 1023.

Nws txhais li cas thaum tus sau yog txhua tus lej tiag?
Lub luag haujlwm ntawm radical muaj nuj nqi yog ib qho x tus nqi uas lub radicand (tus nqi nyob rau hauv lub radical kos npe) tsis zoo. Qhov no txhais tau tias x + 5 ≧ 0, yog li x ≧ − 5. Txij li thaum lub hauv paus square yuav tsum ib txwm zoo los yog 0, . Tus sau yog txhua tus lej tiag x qhov twg x ≧ − 5, thiab qhov ntau yog txhua tus lej tiag f(x) xws li f(x) ≧ − 2
Yuav ua li cas tsis tu ncua variation txiav txim mole ratio?
Qhov kev sim no siv cov kev hloov pauv tas li los txiav txim siab qhov sib piv mole ntawm ob lub reactants. Nyob rau hauv txoj kev ntawm kev hloov pauv tas mus li, tag nrho cov naj npawb ntawm cov moles ntawm reactants yog khaws cia tas mus li rau ib qho kev ntsuas. Txhua qhov kev ntsuas yog tsim nrog qhov sib txawv mole piv lossis mole feem ntawm cov reactants
Dab tsi yog qhov txawv ntawm qhov ratio ntawm qhov ratio thiab tus nqi?
Ib qho piv txwv piv qhov loj ntawm ob qhov ntau. Thaum qhov ntau muaj qhov sib txawv, ces qhov piv yog hu ua tus nqi. Ib qho piv txwv yog ib nqe lus hais txog kev sib npaug ntawm ob qho piv txwv

Dab tsi yog mole ratio thiab nws siv li cas hauv stoichiometry?
Mole ratios yog siv los ua ib qho kev sib piv ntawm cov tshuaj nyob rau hauv ib qho kev sib npaug tshuaj sib npaug kom txiav txim siab npaum li cas. Yuav tsum muaj pes tsawg moles ntawm Hydrogen roj yuav tsum tau hnov mob nrog 5 moles ntawm Nitrogen. Peb tuaj yeem siv cov khoom hloov pauv hauv cov txheej txheem hu ua stoichiometry. Mole ratio muab qhov sib piv los tshem tawm cov chav nyob
