Ntxiv mus, dab tsi yog mechanical mix?
n a sib tov nws cov khoom tuaj yeem raug cais los ntawm txhua yam txhais tau tias. Hom ntawm: sib tov . (chemistry) ib yam khoom uas muaj ob lossis ntau yam khoom sib xyaw ua ke (tsis nyob rau hauv qhov sib npaug thiab tsis muaj tshuaj sib txuas)
Tsis tas li ntawd, cov av puas yog qhov sib xyaw ua ke? (a) Av yog heterogeneous, los yog a mechanical sib tov , vim koj tuaj yeem pom ntau dua ib feem. (b) Tshuaj tsw qab yog kev daws, los yog homogeneous. Koj tuaj yeem pom tsuas yog ib feem, tab sis naj hoom yog a sib tov ntawm cov khoom xyaw. (c) Baking hmoov yog ib yam khoom ntshiab.
Ib tug kuj yuav nug, dab tsi yog ib qho piv txwv ntawm kev sib xyaw tshuab?
A Mechanical Mixture yog thaum. ob lossis ntau yam khoom sib txawv yog. sib xyaw ua ke tab sis pom tau, tab sis tag nrho ib qho, zoo li cov xuab zeb thiab pob zeb ntawm lub puam lossis mis nyuj hauv cereal hauv ib lub tais. Mechanical Mixture yog tsim/tsim.
Puas yog hmoov nplej yog qhov sib xyaw ua ke?
Nplej nplej yog ib mechanical sib tov . Cov nplej nplej muaj peb ntu: bran, endosperm, thiab kab mob (Daim duab 2). Hlau rollers tawg qhib, los yog zeb, cov nplej nplej. Whole-wheat hmoov yog hmoov uas yog tsim los ntawm tag nrho peb feem ntawm cov nplej nplej.

Puas yog pob zeb ua homogeneous lossis heterogeneous sib xyaw?
Pob zeb yog cov khoom sib xyaw ua ke uas muaj cov cement, dej, nplua aggregates thiab coarse aggregates. Cov khoom siv tau hais tias yog homogeneous thaum nws cov khoom zoo ib yam hauv txhua qhov kev qhia. Txwv tsis pub nws yog cov khoom siv heterogeneous. Cement tej zaum yuav hu ua homogeneous khoom
Puas yog baking soda yog homogeneous lossis heterogeneous sib xyaw?
Heterogeneous sib tov tsis sib xws. Txhua qhov sib xyaw uas muaj ntau tshaj ib theem ntawm cov teeb meem yog qhov sib xyaw heterogeneous. Qhov no tuaj yeem yog qhov nyuaj vim tias kev hloov pauv ntawm cov xwm txheej tuaj yeem hloov pauv qhov sib xyaw. Piv txwv li, ib qho dej qab zib uas tsis tau qhib hauv lub raj mis muaj ib qho sib xyaw ua ke thiab yog ib qho sib xyaw ua ke
Puas yog xuab zeb thiab dej homogeneous lossis heterogeneous?
Teb chaws As Mes Lis Kas: yog xuab zeb thiab dej yog homogeneous sib tov? Yog nws yog. Kev sib xyaw heterogeneous txhais tau tias koj tuaj yeem pom cov khoom ntawm tus kheej thiab cais lawv lub cev. Koj tuaj yeem pom cov xuab zeb hauv dej txawm tias koj swirl lawv ua ke
Puas yog vanadium oxide yog ib qho catalyst heterogeneous?
Lub vanadium (V) oxide yog ib qho heterogeneous catalyst vim nws nyob rau hauv cov khoom theem thiab cov reactants yog tag nrho cov gaseous. Cov reactants yog adsorbed rau saum npoo ntawm cov catalyst (uas yog tshuaj hloov los ntawm cov txheej txheem) tab sis txhua lub sij hawm cov catalyst tseem yog ib feem ntawm cov khoom nto
Puas yog Colloid yog homogeneous lossis heterogeneous sib xyaw?
Ib qho colloid yog ib qho sib xyaw uas cov khoom me me ntawm ib yam khoom sib npaug sib npaug thoob plaws lwm yam khoom. Mis yog sib xyaw ntawm cov kua butterfat globules dispersed thiab tshem tawm hauv dej. Colloids feem ntau suav hais tias yog cov khoom sib xyaw ua ke, tab sis muaj qee qhov zoo ntawm homogeneous sib xyaw thiab
