A molecular formula muaj cov tshuaj cov cim rau cov ntsiab lus ua raws li cov ntawv sau npe piav qhia txog tus lej ntawm atoms ntawm txhua lub ntsiab lus muaj nyob hauv molecule . Lub empirical qauv sawv cev rau qhov yooj yim tshaj plaws tag nrho-tus lej piv ntawm atoms hauv acompound.
Ib yam li ib tug yuav nug, koj yuav nrhiav tau cov mis molecular li cas?
Faib cov molar mass ntawm lub compound los ntawm empirical qauv pawg. Cov txiaj ntsig yuav tsum yog tus lej tag nrho lossis ze rau tag nrho tus lej. Muab tag nrho cov subscripts hauv theem pirical qauv los ntawm tag nrho cov naj npawb pom nyob rau hauv kauj ruam 2. Theresult yog tus molecular formula.
Kuj Paub, puas yog molecular mis tib yam li tshuaj formula? A tshuaj formula qhia peb tus lej ntawm atoms ntawm txhua lub ntsiab lus hauv ib qho chaw. Muaj ntau hom cov qauv tshuaj thiab txhua hom muab peb cov ntaub ntawv sib txawv txog a tshuaj yam khoom. Qhov sib txawv ntawm cov qauv tshuaj suav nrog: molecular , empirical, structural thiab condensed structural cov qauv.
Kuj kom paub yog, koj sau cov qauv molecular hauv Lo Lus li cas?
Hauv koj Lo lus file, sau a qauv , rau piv txwv H2SO4. Ntaus H. Ces, ntawm lub Tsev tab, hauv pawg Font, nyemSubscript. Los yog nias CTRL + =.
Dab tsi yog molecular mis nrog piv txwv?
Cov molecular formula ntawm ib tug compound tej zaum yuav theempirical qauv , los yog nws yuav yog ib tug ntau yam ntawm empirical qauv . Rau piv txwv , cov molecular formula ofbutene, C4H8, qhia tau hais tias txhua tus dawb huv uas twb muaj lawm molecule ntawm butene muaj plaub atoms ntawm carbon thiab yimatom ntawm hydrogen.

Cov ntaub ntawv dab tsi ua rau cov ntawv sau npe hauv cov tshuaj formula muab?
Cov ntawv lossis cov ntawv uas sawv cev rau lub ntsiab lus hu ua nws lub cim atomic. Cov lej tshwm sim raws li cov ntawv sau npe hauv cov qauv tshuaj qhia txog tus lej ntawm atoms ntawm lub caij tam sim ua ntej subscript. Yog tias tsis muaj subscript tshwm sim, ib qho atom ntawm lub ntsiab yog tam sim no
Vim li cas peb thiaj li kho cov coefficients thaum ntsuas cov tshuaj sib npaug thiab tsis yog cov ntawv sau npe?
Thaum koj hloov cov coefficients, koj tsuas yog hloov tus naj npawb ntawm cov molecules ntawm cov khoom tshwj xeeb. Txawm li cas los xij, thaum koj hloov cov ntawv sau npe, koj tab tom hloov cov tshuaj nws tus kheej, uas yuav ua rau koj qhov sib npaug tshuaj tsis raug
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
