A compound yog ib yam khoom ntshiab uas muaj ob los sis ntau dua atoms sib txawv tshuaj ua tsaug rau ib leeg. A compound tau raug puas tsuaj los ntawm tshuaj txhais tau tias . Tej zaum nws yuav yog tawg ua yooj yim dua tshuaj sib xyaw , nyob rau hauv nws cov ntsiab lus los yog ib tug ua ke ntawm ob.
Yog li ntawd, ib qho kev sib xyaw puas tuaj yeem tawg los ntawm lub cev?
Cov ntsiab lus tsis tuaj yeem ua tau tawg rau hauv txhua yam yooj yim lub cev los yog tshuaj. Cov tshuaj : yog cov khoom ntshiab uas tsim los ntawm ntau tshaj li hom atom thiab ua tau ua tawg los yog decomposed rau hauv nws tus kheej cov ntsiab lus los ntawm chemical txoj kev , tab sis tsis tuaj yeem sib cais los ntawm txoj kev siv lub cev.
Ib yam li ntawd, cov tebchaw puas tuaj yeem tawg los ntawm kev pom? Cov tshuaj ntshiab yog ntxiv tawg hauv cov ntsiab lus thiab tshuaj sib xyaw . Mixtures yog lub cev sib xyaw ua ke uas ua tau muab cais rau hauv lawv cov khoom qub. Ntau yam kev sib cais muaj nyob rau hauv thiaj li yuav cais cov teeb meem, suav nrog suav nrog distillation, lim , evaporation thiab chromatography.
Ntawm no, yam khoom twg tuaj yeem tawg los ntawm kev siv tshuaj?
Magnesium Methanol yog qhov sib xyaw ua ke ntawm carbon, hydrogen, thiab oxygen. Cov tshuaj tuaj yeem tawg nyob rau hauv lawv cov componenets los ntawm tshuaj txhais tau tias . Lwm qhov kev xaiv yog cov ntsiab lus. Hauv lwm qhov kev xaiv thawj yam khoom yog ib qho compound thiab qhov thib ob yam khoom yog ib yam.
Ua li cas koj rhuav tshem cov tshuaj lom neeg?
Cov tshuaj tuaj yeem tawg sib nrug hauv tshuaj cov tshuaj tiv thaiv hu ua decomposition reactions. Piv txwv li, dej tuaj yeem tawg nqes rau hauv cov ntsiab lus diatomic hydrogen gas thiab oxygen gas hauv a tshuaj cov tshuaj tiv thaiv hu ua electrolysis. Sodium chloride kuj tuaj yeem tawg nqes mus rau hauv lub ntsiab lus sodium thiab chlorine gas los ntawm electrolysis.

Koj puas tuaj yeem qhia los ntawm cov kev nqus dej no seb lub teeb liab puas ua haujlwm zoo hauv kev tsav tsheb photosynthesis?
Ib qho tsis tuaj yeem qhia los ntawm daim duab no, tab sis vim tias chlorophyll ib lub teeb liab, peb tuaj yeem kwv yees tias nws yuav ua tau zoo hauv kev tsav tsheb photosynthesis. Cov xim no muaj peev xwm nqus tau ntau lub teeb ntawm lub teeb (thiab yog li ntau lub zog) dua li chlorophyll ib leeg tuaj yeem nqus tau
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
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Ob lub tebchaw puas tuaj yeem siv los ua cov tshuaj reactants rau cov tshuaj tiv thaiv synthesis?
7. Ob lub ntsiab lus puas tuaj yeem siv los ua cov reactants rau cov tshuaj tiv thaiv synthesis? Yog tias muaj, muab tsawg kawg ib qho piv txwv los ntawm Qauv 1 los txhawb koj cov lus teb. Ob lub ntsiab lus thiab cov tebchaw tuaj yeem pom hauv cov khoom ntawm cov tshuaj tiv thaiv decomposition
Cov tshuaj dab tsi tuaj yeem txav mus rau hauv lossis tawm ntawm cov hlwb los ntawm kev nthuav tawm?
Dej, carbon dioxide, thiab oxygen yog ib qho ntawm ob peb yam yooj yim molecules uas muaj peev xwm hla lub cell membrane los ntawm diffusion (los yog ib hom diffusion hu ua osmosis). Diffusion yog ib txoj hauv kev ntawm kev txav ntawm cov khoom nyob rau hauv cov hlwb, nrog rau txoj kev rau cov me me molecules tseem ceeb hla lub cell membrane
