A colloid yog a sib tov qhov twg me me ntawm ib yam khoom sib npaug sib npaug thoob plaws lwm yam khoom. Mis yog ib sib tov ntawm cov kua butterfat globules dispersed thiab tshem tawm hauv dej. Colloids feem ntau xav txog heterogeneous sib tov , tab sis muaj qee qhov zoo ntawm homogeneous sib tov ib yam nkaus.
Ib yam li ntawd ib tug yuav nug, yog vim li cas ib tug colloid yog heterogeneous sib tov?
A colloid yog a heterogeneous sib tov nyob rau hauv uas cov dispersed hais yog nruab nrab nyob rau hauv loj ntawm cov tshuaj thiab ib tug ncua kev kawm ntawv. Vim hais tias cov dispersed hais ntawm a colloid tsis loj npaum li cov kev ncua, lawv tsis nyob ntawm qhov sawv.
Tom qab ntawd, lo lus nug yog, hom kev sib tov twg yog colloid? Colloids. Lub colloid yog ib qho sib xyaw heterogeneous uas nws qhov loj me yog nruab nrab ntawm cov ntawm a daws thiab a kev ncua . Dispersed hais yog kis tusyees nyob rau hauv lub dispersion nruab nrab, uas yuav ua tau ib tug khoom, kua, los yog roj.
Yog li ntawd, yog colloidal tov homogeneous los yog heterogeneous?
Ib qho kev daws teeb meem colloidal, qee zaus raug txheeb xyuas raws li kev ncua kev kawm colloidal, yog a sib tov nyob rau hauv uas cov tshuaj yog tsis tu ncua ncua nyob rau hauv ib tug kua. Ib qho colloid yog ib yam khoom me me uas tsis tu ncua kis mus rau lwm yam khoom. Cov no yog heterogeneous nyob rau hauv Xwm tab sis zoo li yuav homogeneous.
Dab tsi yog cov piv txwv ntawm heterogeneous thiab homogeneous sib tov?
Piv txwv ntawm homogeneous sib tov muaj xws li cua, saline tov, feem ntau alloys, thiab bitumen. Piv txwv ntawm heterogeneous mix suav nrog xuab zeb, roj thiab dej, thiab nqaij qaib noodle kua zaub.

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 Oxygen yog cov khoom sib xyaw lossis sib xyaw?
Puas yog oxygen yog ib qho khoom sib xyaw lossis sib xyaw? Oxygen yog ib yam khoom. Nws yog tsim los ntawm tib hom atom, oxygen atoms (8 protons). Nws tshwm sim kom ruaj khov tshaj li molecules ntawm muaj pes tsawg leeg
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 cov pa roj carbon dioxide yog qhov sib xyaw lossis sib xyaw?
CO2 yog lub npe hu ua carbon dioxide. Ib lub ntsiab yog ib yam khoom ua los ntawm ib hom atom. Cov tshuaj uas tsim cov khoom sib tov tuaj yeem yog cov khoom lossis cov khoom sib txuas, tab sis cov khoom sib tov tsis tsim cov tshuaj sib txuas. Cov khoom sib xyaw tuaj yeem sib cais rau hauv lawv cov khoom qub ib zaug ntxiv (kwv yees) yooj yim
Puas yog hluav taws xob yog cov khoom sib xyaw lossis sib xyaw?
Kev tshuaj xyuas cov ntsiab lus, cov khoom sib xyaw, thiab cov khoom sib xyaw Ionic Cov Khoom Siv Covalent Sib Nqus Sib cais rau hauv cov khoom siv hluav taws xob hauv dej kom muab cov kev daws teeb meem uas ua hluav taws xob nyob twj ywm zoo li qub molecule hauv dej thiab yuav tsis ua hluav taws xob
