Kev sib xyaw heterogeneous yog sib xyaw ntawm ob lossis ntau dua tshuaj tshuaj ( cov ntsiab lus los yog compounds), qhov twg cov khoom sib txawv ua tau yuav pom qhov txawv thiab yooj yim cais los ntawm lub cev txhais tau tias . Piv txwv li: sib tov ntawm xuab zeb thiab dej.
Ua raws li qhov no hauv kev txiav txim siab, puas tuaj yeem sib xyaw ua ke los ntawm kev siv lub cev?
Cov khoom xyaw - ob lossis ntau yam khoom uas tsis muaj tshuaj lom neeg sib xyaw ua ke thiab ua tau ua cais los ntawm lub cev txhais tau tias . Cov khoom hauv a sib tov khaws lawv cov khoom ntiag tug. Kev daws - ib yam tshwj xeeb ntawm sib tov qhov twg ib yam khoom dissolves nyob rau hauv lwm tus.
Ib sab saum toj no, yam khoom twg tsis tuaj yeem cais tawm ntawm lub cev? Compounds: yog cov khoom ntshiab uas tsim los ntawm ntau tshaj li hom atom thiab tuaj yeem tawg los yog decomposed rau hauv nws tus kheej cov ntsiab lus los ntawm kev siv tshuaj, tab sis tsis tuaj yeem sib cais los ntawm kev siv lub cev. Qhov ratio ntawm cov khoom nyob rau hauv a compound yeej ib txwm tsis tu ncua.
Ib yam li ntawd, ib lub ntsiab tuaj yeem sib cais?
Ib yam khoom ntshiab uas muaj ib hom ATOM nkaus xwb. Ib keeb yog ib txwm uniform tag nrho txoj kev los ntawm (homogeneous). Ib keeb TSIS MUAJ cais rau hauv cov ntaub ntawv yooj yim (tshwj tsis yog thaum muaj kev cuam tshuam nuclear).
Cov khoom puas tuaj yeem muab cais ua qhov me me uas siv cov tshuaj?
Tsis yog, cov ntsiab lus ua tsis tau cais ua protons, neutrons, thiab electrons los ntawm tshuaj txhais tau tias vim lub zog xav tau los ua qhov no ntau dua ua tau raug tsim los ntawm tshuaj txhais tau tias . Tsis tas li ntawd, cov ntsiab lus tsis tuaj yeem tsim los ntawm kev sib txuas cov khoom yooj yim.

Yam tshuaj twg tsis tuaj yeem decomposed los ntawm cov tshuaj txhais tau tias?
Cov ntsiab lus yog cov khoom ntshiab uas tsis tuaj yeem decomposed los ntawm cov tshuaj zoo tib yam xws li cua sov, electrolysis, los yog cov tshuaj tiv thaiv. Kub, nyiaj, thiab oxygen yog piv txwv ntawm cov khoom. Compounds yog cov khoom ntshiab tsim los ntawm kev sib xyaw ua ke ntawm cov ntsiab lus; lawv tuaj yeem decomposed byordinary tshuaj txhais tau tias
Cov khoom puas tuaj yeem muab cais ua cov khoom yooj yim?
Cov ntsiab lus tsis tuaj yeem tawg mus rau hauv cov khoom yooj yim. Ib yam li ntawd, ib lub ntsiab lus tsis tuaj yeem hloov pauv mus rau hauv ib lub caij sib txawv. Cov khoom siv tshuaj yog qhov yooj yim ntawm cov khoom
Peb puas tuaj yeem cais tus ncej sib nqus los ntawm cov hlau nplaum?
Hloov chaw, ob lub sib nqus ncej tshwm sim ib txhij los ntawm kev sib sau ua ke ntawm txhua qhov tam sim no thiab lub sijhawm nyob rau hauv cov hlau nplaum. Vim li no, ob tug ncej ntawm ib tug sib nqus dipole yuav tsum yeej ib txwm muaj sib npaug zos thiab opposite lub zog, thiab ob tug ncej tsis tuaj yeem sib cais los ntawm ib leeg
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Txoj cai thermodynamic twg hais tias koj Tsis tuaj yeem hloov 100 feem pua ntawm cov cua sov rau hauv cov khoom siv hluav taws xob ntawm cov lus teb xaiv?
