Txoj hauv kev no tau raug coj los siv rau txoj kev kawm no. Stoichiometry cov ntsiab lus qhia nyob rau theem nrab, feem ntau yog rauqib 11 thiab qib 12, koom nrog kev daws teeb meem thiab nyob rau hauv kev sawv ntawm cov tshuaj tiv thaiv thiab kev sib npaug.
Vim li cas stoichiometry nyuaj?
Stoichiometry tuaj yeem nyuaj vim nws tsim los ntawm tus lej ntawm tus kheej. Yuav kom ua tiav koj yuav tsum paub cov txuj ci thiab kawm paub npaj koj li kev daws teeb meem li cas. Xwb txhua yam ntawm cov kev txawj no ua ntej mus rau: xam Molar Mass.
Puas yog stoichiometry qhov nyuaj tshaj plaws ntawm chemistry?
Stoichiometry yog qhov sib cav ib lub tswv yim nyuaj tshaj plaws rau cov tub ntxhais kawm kom nkag siab hauv chav kawm chemistry dav dav. … Ntau lub sij hawm cov kws qhia ntawv ua txhaum cai rau txoj hauv kev los daws cov teeb meem stoichiometry, uas tuaj yeem tiv thaiv cov tub ntxhais kawm los ntawm kev nkag siab tag nrho lub tswv yim ntawm cov tshuaj tiv thaiv lawv tau piav qhia.
Puas stoichiometry yooj yim?
Cov tub ntxhais kawm, txawm li cas los xij, feem ntau pom cov teeb meem stoichiometry nyuaj vim lawv suav nrog cov lej ntawm cov tshuaj moles. Tus yuam sij rau kev ua cov teeb meem stoichiometry yooj yim yog los txais yuav thiab xyaum txoj hauv kev rau cov teeb meem. Ntsuas qhov sib npaug ntawm cov tshuaj tiv thaiv kab mob.
Dab tsi yog qhov taw qhia ntawm stoichiometry?
Stoichiometry ntsuas cov kev sib raug zoo ntau yam, thiab yog siv los txiav txim siab txog cov khoom thiab cov tshuaj reactants uas yogtsim los yog xav tau nyob rau hauv ib tug muab tshuaj tiv thaiv. Piav txog qhov kev sib raug zoo ntawm cov tshuaj thaum lawv koom nrog cov tshuaj tiv thaiv kab mob hu ua cov tshuaj tiv thaiv stoichiometry.

Leej twg qhia tus qauv kev qhuab qhia tus kheej?
Skinner's Kev Tshawb Fawb thiab Tib Neeg Tus Cwj Pwm muab kev tshawb fawb ntawm cuaj pawg ntawm txoj kev tswj tus kheej. Leej twg nrhiav tau kev qhuab ntuas? Ntau tshaj 40 xyoo dhau los, W alter Mischel, PhD, tus kws kho mob hlwb tam sim no ntawm Columbia University, tshawb nrhiav kev tswj tus kheej hauv cov menyuam yaus nrog kev sim yooj yim tab sis ua tau zoo.
Thaum twg siv i.e. thiab thaum twg siv xws li?
I.e. yog ib qho luv luv rau kab lus id est, uas txhais tau tias "uas yog." I.e. yog siv los rov hais dua ib yam dab tsi uas tau hais yav dhau los txhawm rau kom meej nws lub ntsiab lus. E.g. luv luv rau exempli gratia, uas txhais tau tias "
Thaum twg siv polyacrylamide thiab thaum twg agarose?
Agarose gels siv nrog DNA, vim qhov loj ntawm biomolecules (DNA feem ntau yog ntau txhiab kDa). Rau cov protein gels, polyacrylamide muab daws teeb meem zoo, raws li qhov me me me (50 kDa yog qhov raug) zoo dua rau qhov sib txawv ntawm cov gel.
Vim li cas stoichiometry tseem ceeb?
Muab cov tshuaj tiv thaiv tshuaj, stoichiometry qhia peb seb qhov ntau npaum li cas ntawm txhua qhov reactant peb xav tau txhawm rau kom tau txais peb cov khoom xav tau txaus. Vim tias nws kev siv lub neej tiag tiag hauv kev tsim tshuaj lom neegnrog rau kev tshawb fawb, stoichiometry yog ib qho tseem ceeb tshaj plaws thiab cov ntsiab lus tseem ceeb hauv chemistry.
Sib qhia daim ntawv qhia hnub nyob qhov twg?
Ntawm lub Tsev tab, hauv Pab Pawg Sib Koom, nyem Qhia Calendar. Hauv Kev Sib Tham Caw uas tshwm sim, nkag mus rau tus neeg uas koj xav qhia rau hauv lub thawv To. Nkag mus lossis xaiv lwm yam kev xaiv uas koj xav tau, ib yam li koj tau xa email.
