Txiav txim siab tus feem pua rov qab los ntawm distillation los ntawm kev faib cov nyiaj ntawm distilled ua kua rov zoo los ntawm vapor los ntawm thawj tus nqi ntawm cov kua. Qhov no qhia koj seb qhov feem pua ntawm cov kua qub yog dab tsi distilled nyob rau hauv cov tshuaj ntau concentrated.
Ua raws li qhov no, koj yuav ua li cas xam cov feem pua rov qab los ntawm distillation?
Feem pua rov qab = tus nqi ntawm cov khoom koj tau sau tau / tus nqi ntawm cov khoom koj yuav tsum tau sau, raws li a feem pua . Cia peb hais tias koj muaj 10.0g ntawm cov khoom tsis huv thiab tom qab recrystallization koj tau sau 7.0 g ntawm cov khoom ntshiab qhuav. Ces koj feem pua rov qab los yog 70% (7/10 x 100).
Ib yam li ntawd, qhov feem pua rov qab qhia koj li cas? Feem pua rov qab suav cov feem pua ntawm ib yam khoom qub uas rov qab los tom qab tshuaj tiv thaiv yog ua tiav. Cov no feem ntau suav nrog kev ua kom huv huv. Nws kuj txiav txim siab lawv efficiency.
Kuj paub, dab tsi yog rov qab hauv distillation?
Cov rov qab los txhais tau tias yog ib feem ntawm lub teeb tivthaiv nyob rau hauv lub pub uas yog tsim nyob rau hauv lub distillate cov khoom ntws. Tag nrho cov molar thiab lub teeb sib npaug rau qhov sib cais binary yog cov kev sib raug zoo ib txwm muaj.
Multicomponent distillation yog dab tsi?
l·tē·k?m¦pō·n?nt 'dist·?l'ā·sh?n] (chemical engineering) The distillation Kev sib cais ntawm ib qho kua dej uas muaj peb lossis ntau dua cov khoom rau hauv ib qho khoom siv nyiaj siv ua haujlwm thiab ib qho khoom hauv qab.

Koj ua li cas xam cov peev xwm thim rov qab?
Rau ib qho ion muab, qhov kev thim rov qab tuaj yeem suav tau los ntawm Nernst kab zauv qhov twg: R = gas tas li. T = kub (in oK) z = ion charge. Equilibrium (los yog thim rov qab) muaj peev xwm muaj peev xwm so ntawm -12 mV (raws li tsim los ntawm Na + / K + ATPase) tsis muaj voltage- lossis ligand-gated channels. thaum xub thawj, tsis muaj cov pa xau
Yuav ua li cas koj coj ib tsob ntoo willow rov qab rau txoj sia?
Kev saib xyuas sai yuav tsum tau muab rau lub willow yog tias koj pom tias muaj nplooj hloov pauv, stunted loj hlob lossis defoliation. Ncuav 70 feem pua dej cawv thiab 30 feem pua dej rau hauv lub raj mis tsuag. Khawb ib sab ntawm txhua qhov suckers loj hlob los ntawm cov hauv paus pob ntawm koj tsob ntoo willow
Yuav ua li cas koj coj ib tug quaj willow rov qab rau txoj sia?
Weeping willows tuaj yeem rov qab los ntawm ntau yam teeb meem loj. Tshem cov kab mob, twigs thiab tawv ntoo nrog ib txhais tes los yog riam. Dej kom huv si tab sis tsis tu ncua kom ntseeg tau tias koj qhov kev quaj ntsuag yuav tsis raug kev ntxhov siab hauv dej, tshwj xeeb tshaj yog thaum tsob ntoo muaj kev noj qab haus huv
Koj tuaj yeem qhia tau li cas yog tias muaj kev cuam tshuam rau pem hauv ntej lossis thim rov qab?
Yog tias K K, cov reactants tau txais kev pom zoo. Yog tias Q< K, cov khoom raug nyiam
Yuav ua li cas thaum electrons rov qab los rau hauv av?
Lub atom hloov pauv ntawm lub xeev hauv av mus rau lub xeev zoo siab los ntawm kev siv lub zog los ntawm nws qhov chaw nyob ib puag ncig hauv cov txheej txheem hu ua nqus. Cov electron absorbs lub zog thiab dhia mus rau qib siab zog. Nyob rau hauv cov txheej txheem rov qab, emission, lub electron rov qab mus rau hauv av lub xeev los ntawm kev tso lub zog ntxiv nws absorbed
