Homogeneous Mixtures Cov dej ntsev tau piav saum toj no yog homogeneous vim cov ntsev yaj tau sib npaug sib npaug thoob plaws tag nrho cov qauv dej ntsev. Feem ntau nws yog ib qho yooj yim rau confuse ib homogeneous sib tov nrog cov khoom ntshiab ntshiab hauv chemistry, cov tshuaj yog ib daim ntawv ntawm cov teeb meem uas muaj cov tshuaj tsis tu ncua thiab cov yam ntxwv zoo … Ob lossis ntau lub ntsiab lus ua ke rau hauv ib yam khoom los ntawm cov tshuaj tiv thaiv, xws li dej, tsim cov tshuaj lom neeg. Tag nrho cov tebchaw yog cov khoom, tab sis tsis yog txhua yam khoom yog cov khoom sib txuas. https://courses.lumenlearning.com › khoom-and-mixtures

vim ob leeg yeej ib yam.
Yuav ua li cas sib tov yog seawater?
Seawater is a Solution
(B) Seawater is a kev sib xyaw ntawm cov dej ntshiab thiab yaj ionic tshuaj. Dej yog cov kuab tshuaj zoo heev. Cov kuab tshuaj yog cov kua uas yaj lwm yam tshuaj.
YPuas yog seawater piv txwv ntawm homogeneous?
Seawater yog ib qho piv txwv ntawm a tov, uas yog homogeneous sib tov…
YPuas yog seawater homogenous lossis heterogenous sib tov?
Ntshav ntsev muaj ntsev yaj, yog li nws yog homogeneous sib tov vim peb tsis tuaj yeem cais ntsev ntawm nws ncaj qha. Tab sis nws kuj tseem hu ua qhov sib xyaw ua ke vim tias muaj cov impurities thiab cov khoom tsis zoo xws li cov xuab zeb, cov plhaub ua los ntawm calcium carbonate, thiab microbes hauv nws.
YPuas yog dej hiav txwv homogeneous lossis heterogeneous sib tov?
Qhov no yog vim dej hiav txwv tuaj yeem faib ua ob homogeneous thiab heterogeneous sib tov Nws yog hu ua homogeneous vim tias nws muaj cov ntsev yaj hauv nws thiab nws kuj tseem hu ua heterogeneous vim nws muaj ntau yam insoluble Cheebtsam ib yam li xuab zeb, microbes thiab lwm yam.

Thaum twg huab cua yog homogeneous sib xyaw?
Huab cua yog homogeneous sib xyaw ntawm cov khoom siv roj nitrogen, oxygen, thiab lwm cov khoom me me ntsev, suab thaj, thiab cov tshuaj yaj hauv dej kom sib xyaw ua ke. Ib homogeneous sib tov uas muaj ob qho tib si solute thiab hnyav tam sim no kuj yog ib qho kev daws.
Puas cov sib xyaw ua ke sib txawv ntawm cov khoom?
Ib qho sib xyaw ua ke yog kev sib xyaw ntawm ob lossis ntau yam tshuaj lom neeg (cov ntsiab lus lossis cov khoom sib txuas), qhov twg cov khoom sib txawv tuaj yeem pom qhov txawv thiab yooj yim sib cais los ntawm lub cev txhais tau tias . Puas yog cov ntsiab lus sib txawv?
Puas yog sib xyaw ua ke sib cais?
Heterogeneous Mixtures Ib qho sib xyaw heterogeneous yog sib xyaw ntawm ob lossis ntau yam tshuaj lom neeg (cov ntsiab lus lossis cov khoom sib txuas), qhov sib txawv ntawm cov khoom tuaj yeem pom qhov txawv thiab yooj yim cais los ntawm lub cev txhais tau tias .
Koj puas tuaj yeem sib xyaw cov roj sib txawv?
Yog, koj tuaj yeem sib tov ib hom roj zoo(xws li Mobil 1) nrog lwm hom (xws li AMSOIL) lossis cov roj pa nrog cov roj hluavtaws (qhov tseeb, qhov ntawd yog dab tsi. synthetic blend yog). Feem ntau cov khoom hluavtaws niaj hnub no tau sib haum nrog cov roj pa thiab tuaj yeem sib xyaw kom zoo .
Yog ntsev yog ib qho khoom xyaw lossis sib xyaw?
S alt is lwm compound. Nws cov qauv tshuaj yog NaCl, uas sawv cev rau sodium chloride . Yog ntsev yog ib qho khoom lossis cov khoom sib xyaw? Tshuaj, cov ntsev ntsev muaj ob lub ntsiab lus, sodium (Na) thiab chloride (Cl). Tsis yog lub ntsiab lus tshwm sim sib cais thiab dawb hauv cov xwm txheej, tab sis pom muaj khi ua ke raws li compound sodium chloride .
