“ Ntshiab ” xab npum feem ntau yog ua los ntawm nqaij nyug siab thiab sodium hydroxide thiab tuaj yeem hu ua sodiumtallowate. Tab sis nqaij nyuj siab zoo li nrog rau feem ntau lossis tag nrho lwm cov roj ntsha uas tshwm sim yog ib qho triglyceride ntawm kev sib xyaw ntawm fattyacids.
Tsis tas li ntawd, cov xab npum puas yog ib qho sib xyaw lossis tshuaj?
xab npum yog sib tov los yog ntshiab yam khoom.
Ib yam li ntawd, cov av puas yog cov khoom ntshiab? av yog ib tug heterogeneous sib tov ntawm xuab zeb, av nplaum, organic tshuaj zoo li cov nroj tsuag tuag thiab dej. Av tsis yog a cov khoom ntshiab tab sis sib tov. Qhov no mix yog heev complex nyob rau hauv nws muaj pes tsawg leeg. Organic Constitution ntawm av los ntawm ntau yam tuag decaying qhov chaw ntawm cov nroj tsuag thiab tsiaj txhu.
Ib yam li ntawd, cov ntxhua khaub ncaws puas yog cov khoom ntshiab?
Tag nrho tab sis cov dej ntshiab tshaj plaws muaj cov dej ntxhia thiab cov pa. Cov no yog yaj thoob plaws hauv dej, yog li cov khoom sib xyaw ua ke nyob rau hauv tib theem thiab yog homogeneous. Liquid ntxhua khaub ncaws yog lwm qhov piv txwv ntawm homogeneous sib tov ntawm ntau yam xab npum thiab tshuaj rau ntxuav khaub ncaws.
Cov qauv twg yog cov khoom ntshiab?
Piv txwv ntawm cov khoom ntshiab yog dej, nyiaj, zinc oxide, rooj ntsev, ethanol, thiab lwm yam.

Pizza puas yog ib yam khoom ntshiab lossis sib xyaw?
Yog li pizza tsis yog qhov sib xyaw. Nws yog qhov sib xyaw ntawm ntau yam xws li khob noom cookie, ntses, nqaij, veggies, cheese, thiab lwm yam thiab txhua yam ntawm cov khoom no yog sib xyaw ntawm lwm yam xws li cov protein, starches, qab zib, dej, fiber, vitamins, minerals, thiab lwm yam
Qhov twg ntawm xab npum molecule yog nonpolar?
Qhov ntev hydrocarbon saw yog tsis-polar thiab hydrophobic (repelled los ntawm dej). ' ntsev' kawg ntawm xab npum molecule yog ionic thiab hydrophilic (dej soluble)
Puas yog cov pa roj carbon dioxide yog cov khoom ntshiab?
Yog, carbon dioxide yog cov khoom ntshiab tsis yog sib tov. Piv txwv ntawm cov khoom ntshiab muaj xws li hlau, nyiaj, mercury thiab lwm yam. Thiab cov tebchaw xws li dej, carbon dioxide, methane, vinegar
Puas yog acetone yog cov khoom sib xyaw lossis cov khoom?
Acetone yog cov kua uas tsis muaj xim, flammable kua uas evaporates yooj yim. Nws yog ib qho organic compound vim tias carbonatoms muaj nyob rau hauv acetone cov tshuaj formula, uas yog (CH3) 2O. Nws muaj peb carbon atoms, rau hydrogen atoms, thiab ib tug oxygen atom
Vim li cas xab npum thiaj li txo qhov nro ntawm dej?
Cov xab npum molecules yog tsim los ntawm cov saw ntev ntawm carbon thiab hydrogen atoms. Txij li thaum lub zog nro ntawm qhov chaw ua me me vim qhov kev ncua deb ntawm cov dej molecules nce, cov xab npum intervening molecules txo qhov nro ntawm qhov chaw
