Ntshiab hydrogen yog a cov khoom ntshiab . Ntshiab cawv tuaj yeem yog ethanol, methanol, lossis a sib tov ntawm cov cawv sib txawv, tab sis sai li sai tau thaum koj ntxiv dej (uas tsis yog cawv ), koj tsis muaj ib tug lawm cov khoom ntshiab.
Yog li ntawd, isopropyl cawv puas yog cov tshuaj ntshiab lossis sib xyaw?
1 Teb. Isopropyl cawv los yog rubb cawv yog ib yam khoom homogeneous; nws yog a cov khoom ntshiab
Tom qab ntawd, lo lus nug yog, yog cawv yog sib tov lossis sib xyaw? Technically, cawv yog lub npe ntawm chav kawm ntawm cov organic tebchaw uas muaj ib lossis ntau pawg hydroxyl. Ib qho azeotrope yog a sib tov ntawm ob lossis ntau dua cov kua uas nws cov proportions tsis tuaj yeem hloov pauv los ntawm qhov yooj yim distillation.
Xav txog qhov no, puas yog hmoov nplej dawb huv lossis sib xyaw?
A cov khoom ntshiab yog teeb meem uas tsuas muaj ib leeg xwb yam khoom . A cov khoom ntshiab tsis tuaj yeem tawg ua ib qho yooj yim yam khoom . A sib tov yog teeb meem uas yog ua los ntawm ob los yog ntau tshaj cov khoom ntshiab sib xyaw ua ke. Chocolate chip khob noom cookie yog ib qho sib tov ntawm hmoov , qab zib, qe, ntsev, thiab cocoa.
Dab tsi ntawm kev sib tov yog cawv?
Feem ntau wines thiab cawv yog homogeneous sib tov . Kev tshawb fawb ntawm kev ua cawv thiab cawv yog nyob ntawm kev ua haujlwm ethanol thiab / los yog dej ua kuab tshuaj ntawm ntau yam tshuaj - charred ntoo qhib rau bourbon whiskey, piv txwv li, los yog juniper nyob rau hauv gin - los tsim tshwj xeeb tsw. Dej nws tus kheej yog ib qho piv txwv ntawm homogeneous sib tov.

CO2 yog lub npe hu ua carbon dioxide. Ib lub ntsiab yog ib yam khoom ua los ntawm ib hom atom. Cov tshuaj uas tsim cov khoom sib tov tuaj yeem yog cov khoom lossis cov khoom sib txuas, tab sis cov khoom sib tov tsis tsim cov tshuaj sib txuas. Cov khoom sib xyaw tuaj yeem sib cais rau hauv lawv cov khoom qub ib zaug ntxiv (kwv yees) yooj yim
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
Puas yog Mercury yog cov tshuaj dawb huv lossis sib xyaw?
Mercury ntshiab tsis muaj dab tsi ntxiv tab sis mercury; Nws yog ib qho khoom siv, ib qho ntawm cov khoom siv tshuaj lom neeg los ntawm cov tshuaj lom neeg thiab cov khoom sib xyaw ua ke. Tag nrho cov mercury atoms nyob rau hauv nws yog tib yam, nrog atomic tooj 80. Nws kuj tshwm sim los ua ib tug hlau, zoo li kub los yog nyiaj, uas nws purity yuav ntsuas tau
