Cov teeb meem tsis tuaj yeem tsim los yog rhuav tshem, txawm hais tias itis ib qho khoom, qhov sib xyaw, lossis sib tov . b) Cov kev cai lij choj ntawm qhov tseeb muaj feem cuam tshuam rau cov tebchaw nkaus xwb, vim nws hais txog qhov tsis tu ncua, lossis meej , muaj pes tsawg leeg cov ntsiab lus nyob rau hauv ib tug compound.
Ib yam li ntawd, nws raug nug, puas yog txoj cai ntawm kev muaj pes tsawg leeg siv tau rau cov tebchaw nkaus xwb?
Hauv chemistry, cov kev cai lij choj kev faib ua feem, qee zaum hu ua Proust's txoj cai lub txoj cai ntawm definitecomposition , los yog txoj cai ntawm tas li muaj pes tsawg leeg hais tias ib tug muab tshuaj compound ib txwm muaj nws cov ntsiab lus hauv qhov sib piv (los ntawm pawg) thiab tsis nyob ntawm nws qhov chaw thiab txoj kev npaj.
Ib yam li ntawd, txoj cai ntawm ntau qhov kev faib ua feem siv rau kev sib tov? 2.7 Cov khoom xyaw muaj variable muaj pes tsawg leeg; yog li ntawd, tus nqi yuav txawv. Compounds, raws li cov tshuaj ntshiab, muaj qhov muaj pes tsawg leeg, yog li lawv cov muaj pes tsawg leeg tsis tuaj yeem sib txawv. c) Cov txoj cai ntawm ntau yam proportions siv rau cov tebchaw nkaus xwb, vim nws hais txog kev sib xyaw ntawm cov ntsiab lus rau formcompounds.
Tom qab ntawd, lo lus nug yog, qhov sib tov puas muaj cov ntsiab lus tseeb?
Cov sib tov muaj sib txawv sau ntawv , thaum sib xyaw muaj ib tsau, meej qauv. Thaum sib tov, ib tus neeg cov khoom khaws lawv cov khoom hauv a sib tov , yog hais tias lawv tsim ib tug compound lawv cov khoom ua tau hloov.
Txoj cai ntawm kev txuag cov teeb meem hauv lub xeev li cas?
Cov txoj cai ntawm kev txuag ntawm teeb meem xeev uas inany muab system ntawd yog kaw rau kev hloov ntawm teeb meem , tus nqi ntawm teeb meem nyob rau hauv lub system nyob tsis tu ncua. Teb b. Cov txoj cai ntawm kev txuag ntawm cov teeb meem hais tias nyob rau hauv cov tshuaj tiv thaiv, tag nrho cov huab hwm coj ntawm cov khoom yuav tsum sib npaug tag nrho cov loj ntawm cov reactants.
