Stoichiometry yog lub hauv paus ntawm kev tsim khoom ntawm ntau yam uas koj siv hauv koj lub neej txhua hnub. xab npum, log tsheb, chiv, roj av, deodorant, thiab chocolate tuav tsuas yog ob peb yam khoom koj siv uas yog tsim los ntawm chemically engineered, los yog tsim los ntawm cov tshuaj tiv thaiv.
Ua raws li qhov no hauv kev xav, dab tsi yog kev siv stoichiometry?
Stoichiometry ntsuas cov kev sib raug zoo ntau, thiab yog siv los txiav txim seb tus nqi ntawm cov khoom thiab cov tshuaj reactants uas yog tsim los yog xav tau nyob rau hauv ib tug muab tshuaj tiv thaiv. Piav txog qhov kev sib raug zoo ntawm cov khoom thaum lawv koom nrog cov tshuaj tiv thaiv yog hu ua cov tshuaj tiv thaiv stoichiometry.
Ib yam li ntawd, stoichiometry puas siv hauv khw muag tshuaj? Kawm nyob rau qib 11 Chemistry thiab txuas ntxiv nrog thoob plaws Qib 12 Chemistry, stoichiometry yog kev kawm txog kev sib raug zoo ntawm qhov ntau ntawm cov khoom. Cov kws muag tshuaj siv cov mole thiab ntau yam kev suav uas siv tus nqi no los sib xyaw cov tshuaj uas tsim cov hmoov, ntsiav tshuaj, thiab tshuaj pleev.
Hauv qhov no, stoichiometry siv li cas hauv kev lag luam?
Stoichiometry yog siv hauv kev lag luam Feem ntau los txiav txim siab txog cov khoom siv uas xav tau los tsim cov khoom uas xav tau hauv ib qho kev sib npaug sib npaug. Yuav tsis muaj cov khoom los ntawm cov no kev lag luam tsis muaj tshuaj stoichiometry.
Dab tsi yog stoichiometry hauv chemistry?
Stoichiometry Txhais. Stoichiometry yog kev kawm txog kev sib raug zoo los yog qhov sib piv ntawm ob lossis ntau yam khoom uas tau hloov pauv lub cev lossis tshuaj hloov ( tshuaj tshuaj tiv thaiv). Lo lus los ntawm Greek lo lus: stoicheion (lub ntsiab lus "element") thiab metron (lub ntsiab lus "raug ntsuas").
Pom zoo:
Qhov twg los thawj qhov ntev lossis qhov dav lossis qhov siab?
Dab tsi los ua ntej? Graphics 'kev lag luam tus qauv yog dav los ntawm qhov siab (dav x qhov siab). Txhais tau hais tias thaum koj sau koj qhov ntsuas, koj sau lawv los ntawm koj qhov kev xav, pib nrog qhov dav. Qhov ntawd tseem ceeb
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
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
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
