Xav txog tib yam A thiab B Cheebtsam los tsim a tsis yog - zoo tagnrho daws , nws yuav qhia tsis zoo deviation los ntawm Raoult's Law tsuas yog thaum: Kev sib cuam tshuam-solvent yog muaj zog dua li solute-solute thiab hnyav-solvent kev sib cuam tshuam uas yog , A – B > A – A or B – B.
Ua li no, dab tsi ua rau muaj kev sib txawv ntawm Raoult Txoj Cai?
Yog hais tias cov kuab tshuaj thiab cov kuab tshuaj tsis yog nruj nreem khi rau ib leeg raws li lawv muaj rau lawv tus kheej, ces cov tshuaj yuav qhia ib tug Qhov zoo sib txawv ntawm Raoult txoj cai vim hais tias cov kuab tshuaj molecules yuav pom nws yooj yim dua kom dim ntawm kev daws mus rau theem roj.
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov zoo tshaj plaws thiab tsis zoo tshaj qhov kev daws teeb meem uas hom tsis zoo sib txawv yog qhia los ntawm kev sib xyaw ntawm chloroform thiab acetone? Teb: Kev sib xyaw ntawm chloroform thiab acetone ua -ve kev sib txawv los ntawm Raoult's Law. Cov kev daws teeb meem zoo tshaj plaws yog cov kev daws teeb meem uas ua raws Raoult Txoj Cai ntawm txhua qhov kub thiab txias thaum lub sijhawm cov kev daws teeb meem tsis zoo deviate los ntawm Raoult Txoj Cai ntawm ntau qhov sib txawv thiab qhov kub thiab txias.
Ntawm no, dab tsi yog qhov kev daws teeb meem zoo tshaj plaws thiab tsis yog kev daws teeb meem zoo?
A tsis yog - zoo tagnrho daws yog a daws uas tsis ua raws li txoj cai ntawm ib zoo tagnrho daws qhov twg kev sib cuam tshuam ntawm cov molecules zoo tib yam (los yog ze heev) rau kev sib cuam tshuam ntawm cov molecules ntawm cov khoom sib txawv. Peb xav tias zoo tagnrho khoom rau dilute kev daws teeb meem.
Dab tsi yog txhais los ntawm qhov zoo thiab qhov tsis zoo ntawm Raoult Txoj Cai?
Raoult txoj cai hais tias nyob rau ntawm qhov muab qhov kub thiab txias, lub vapor siab ntawm cov tshuaj uas muaj cov kuab tshuaj tsis hloov pauv yog ncaj qha proportional rau mole feem ntawm cov kuab tshuaj. Cov kev daws teeb meem tsis zoo qhia zoo & tsis zoo sib txawv los ntawm tus cwj pwm zoo.

Albert Einstein txoj kev xav ntawm kev txheeb ze hloov txoj cai ntawm kev txuag hluav taws xob li cas? Thaum ib yam khoom lossis lub cev ua haujlwm rau lwm yam khoom, qee qhov ntawm nws lub zog raug xa mus rau qhov khoom ntawd
Koj yuav txiav txim siab li cas yog tias qhov tsis sib xws tsis muaj kev daws teeb meem?
Cais tawm tus nqi tseeb ntawm sab laug ntawm qhov tsis sib xws. Yog tias tus lej ntawm sab nraud ntawm qhov tsis sib xws yog qhov tsis zoo, koj qhov kev sib npaug tsis muaj kev daws teeb meem lossis tag nrho cov lej tiag tiag li kev daws teeb meem. Siv cov cim ntawm txhua sab ntawm koj qhov tsis sib xws los txiav txim siab qhov twg ntawm cov xwm txheej no tuav
Koj yuav daws tau qhov teeb meem linear programming li cas los ntawm txoj kev ntawm cov ces kaum?
METHOD OF CONNERS Khiav cov teeb tsa ua tau (tej thaj tsam), S. Nrhiav qhov EXACT coordinates ntawm tag nrho cov vertices (kaum cov ntsiab lus) ntawm S. Ntsuas lub hom phiaj muaj nuj nqi, P, ntawm txhua vertex Qhov siab tshaj plaws (yog tias muaj) yog qhov loj tshaj ntawm tus nqi ntawm P ntawm vertex. Qhov tsawg kawg nkaus yog qhov tsawg tshaj plaws tus nqi ntawm P ntawm vertex
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Yuav ua li cas koj thiaj paub yog tias tus nqi tsis sib xws tsis muaj kev daws teeb meem?
Okay, yog tias qhov tseem ceeb tshaj plaws yeej ib txwm zoo lossis xoom tsis muaj txoj hauv kev uas lawv tuaj yeem tsawg dua lossis sib npaug rau tus lej tsis zoo. Yog li ntawd, tsis muaj kev daws teeb meem rau ob qho no. Hauv qhov no yog tias tus nqi tiag tiag yog qhov zoo lossis xoom ces nws yuav nco ntsoov ntau dua lossis sib npaug rau tus lej tsis zoo
