Yooj yim hais, cov ntsiab lus muaj tsuas yog ib hom atoms uas tsis tuaj yeem sib cais. Cov tshuaj muaj cov atom ntawm ob lossis ntau dua cov ntsiab lus khi ua ke thiab tuaj yeem tawg mus rau hauv hom yooj yim ntawm cov teeb meem los ntawm kev siv tshuaj.
Ntawm no, koj tuaj yeem paub qhov txawv ntawm ib qho khoom sib xyaw thiab qhov sib tov li cas?
Zoo li ib keeb , a compound suav hais tias yog ib yam khoom ntshiab (txhais tau tias tsuas muaj ib hom particle hauv cov khoom). A sib tov yog kev sib xyaw ntawm ob lossis ntau yam tshuaj sib txawv tshuaj sib xyaw los yog cov khoom siv hluav taws xob. Nws tsis yog cov khoom ntshiab, tab sis kev sib xyaw ua ke ntau yam.
Tsis tas li ntawd, qhov piv txwv ntawm kev sib txuas yog dab tsi? A compound yog ib yam khoom uas tsim los ntawm ob lossis ntau lub ntsiab lus. Ib txhia piv txwv ntawm tshuaj sib xyaw muaj xws li cov hauv qab no: dej, carbon dioxide, thiab lub rooj ntsev.
Ib yam li ntawd ib tug yuav nug, dab tsi yog cov ntsiab lus thiab cov tebchaw?
Cov ntsiab lus yog cov khoom (xws li hydrogen thiab oxygen) uas tsis tuaj yeem faib ua cov khoom yooj yim. Ib yam khoom zoo li dej, uas yog ua los ntawm ob lossis ntau dua cov ntsiab lus , npe a compound . Dab tsi yog a compound ? Cov tshuaj feem ntau txawv ntawm cov cov ntsiab lus uas tau sib sau ua ke los ua lawv.
Yog mis nyuj sib tov?
Mis yog a sib tov ntawm cov kua butterfat globules dispersed thiab tshem tawm hauv dej. Colloids feem ntau suav hais tias yog heterogeneous sib tov , tab sis muaj qee qhov zoo ntawm homogeneous sib tov ib yam nkaus.
Pom zoo:
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 txoj cai ntawm kev sib xyaw ua ke siv tau rau cov khoom sib xyaw?
Cov teeb meem tsis tuaj yeem tsim los yog rhuav tshem, txawm hais tias itis ib qho khoom, qhov sib xyaw, lossis sib xyaw. b) Txoj cai lij choj ntawm qhov tseeb muaj pes tsawg leeg tsuas yog siv rau cov khoom sib txuas nkaus xwb, vim hais tias nws hais txog qhov tsis tu ncua, lossis qhov tseeb, muaj pes tsawg leeg ntawm cov ntsiab lus hauv ib qho chaw
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
Yuav ua li cas koj txheeb xyuas cov kev sib txuas ntxiv thiab cov kab ntsug?
Cov kaum sab xis yog ob lub kaum sab xis nrog qhov sib npaug ntawm 90º. Cov ces kaum ntxiv yog ob lub kaum sab xis nrog qhov sib npaug ntawm 180º. Vertical angles yog ob lub kaum sab xis uas nws ob sab tsim ob khub ntawm opposite rays. Peb tuaj yeem xav txog cov no yog cov kaum sab xis uas tsim los ntawm X
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
