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.
Vim li cas ntsev yog qhov sib xyaw?
Ntshav yog tshuaj lom neeg ua los ntawm anion thiab cation. Cov ntsev yog tsim los ntawm kev sib dhos ntawm cov ions zoo (cations) thiab tsis zoo them ions (anion.) Cov ntsev ntsev (NaCI) muaj sodium thiab chloride ions thiab nws yog ib qho ionic compound.
Yog ntsev sib tov?
Cov dej ntsev ua haujlwm zoo li nws yog ib yam khoom txawm tias nws muaj ob yam - ntsev thiab dej. Cov dej ntsev yog ib homogeneous sib xyaw, lossis kev daws. Av yog tsim los ntawm cov khoom me me ntawm ntau yam khoom, yog li nws yog qhov sib xyaw ua ke.
10 yam piv txwv ntawm homogeneous yog dab tsi?
Ntawm no yog kaum piv txwv ntawm homogeneous mixs:
- hiav txwv dej.
- Wine.
- Vinegar.
- Steel.
- Brass.
- Air.
- Natural gas.
- ntshav.

Puas ntsev hiav txwv thiab cov ntsev ntsev zoo ib yam?
Hiav txwv ntsev yog ib lo lus dav dav rau cov ntsev uas ua los ntawm cov dej hiav txwv evaporation lossis dej los ntawm cov pas dej ntsev. Nws yog ua tiav tsawg dua li cov ntsev ntsevthiab khaws cov kab hauv av. Cov zaub mov no ntxiv tsw thiab xim.
Puas yog cov dej qab ntsev lossis cov ntses dej ntsev?
Nws yog ib qho chaw nyob hauv ntug dej, cov ntses uas siv nws lub neej feem ntau hauv dej ntsev tab sis tsiv mus rau cov pas dej tshiab thiab cov kwj deg hauv lub caij nplooj ntoo hlav kom loj hlob. Txawm li cas los xij, smelt yog hom hloov tau yooj yim, thiab cov neeg nyob hauv av tau tsim lawv tus kheej los ntawm Maine mus rau Great Lakes thiab sab qab teb Canada .
Puas kev sib txuas lus tsis zoo kuj yog ib qho khoom ntawm kev sib txuas lus?
Kev sib txuas lus tsis zoo ("mis" + "kev sib txuas lus") txhais tau tias yog tsis ua tiav kev sib txuas lus kom txaus thiab zoo Nws yog ib hom kev sib txuas lus teeb meem. … Hom kev sib txuas lus tsis zoo tam sim no tuaj yeem raug cais raws li lub hauv paus ntawm kev tsis sib haum xeeb txog txoj cai sib txuas lus .
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?
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
