Hauv ib qho kev sib xyaw tus (atoms / molecules) yog (chemically / physically) ua ke li ntawd tus cov ntsiab lus uas ua rau tus compound ( khaws cia / poob ) lawv tus kheej thiab ( ua / ua tsis yog) coj ntawm cov khoom tshiab. Hauv ib sib tov , tus tshuaj ( poob / khaws cia ) lawv tus kheej.

Ua li no, cov tebchaw puas khaws lawv tus kheej?

Hauv ib compound cov (atoms / molecules) yog (tshuaj lom neeg lub cev) ua ke kom cov ntsiab lus uas ua rau compound ( khaws cia / poob) lawv tus kheej thiab ( ua do tsis yog) coj ntawm cov khoom tshiab. Qhov tsawg tshaj plaws uas qhia tau tus kheej ntawm a compound yog a(n) molecule uas yog tsim los ntawm atoms uas yog chemically bonded.

Tsis tas li ntawd, vim li cas cov tshuaj hauv cov khoom sib xyaw ua ke khaws lawv cov cim? Sib tov yog kev sib txuas ntawm ob lossis ntau dua yam khoom uas tsis yog chemically ua ke. Tshuaj nyob rau hauv ib tug sib tov kom lawv tus kheej vim tsis muaj tshuaj hloov pauv thaum a sib tov ua.

Ib yam li ntawd ib tug yuav nug, puas sib tov khaws lawv cov khoom?

Mixtures khaws cia tus khoom ntawm lawv constituents vim hais tias cov constituents tsis chemically koom. Ib yam khoom khoom hloov thaum nws reacts chemically tsim ib yam khoom tshiab, tab sis tsis yog thaum nws tau ua ke nrog lwm yam khoom nyob rau hauv a sib tov . Thaum a sib tov daim ntawv muaj tsis muaj tshuaj lom neeg cov tshuaj tiv thaiv.

Puas yog cov khoom sib xyaw ib txwm ua los ntawm cov khoom?

Tseeb/False A sib tov yog ib txwm ua ntawm ib qho kev sib txuas ntawm cov ntsiab lus . Hauv ib sib tov , cov khoom (poob / khaws cia) lawv tus kheej. Nyob rau hauv ib tug compound, lub cov ntsiab lus Kev koom tes (ua tau / tsis tuaj yeem) tau spereated los ntawm cov txheej txheem lub cev yooj yim vim tias cov ntsiab lus yog (lub cev ua ke / chemically bonded).
