Piv txwv . stirring qab zib rau hauv dej yog ib qho piv txwv ntawm dissolving . Cov qab zib yog tus solute, thaum tus dej yog tus kuab tshuaj. Dissolving ntsev hauv dej yog ib qho piv txwv ntawm kev tawg ntawm ib qho ionic compound.
Hais txog qhov no, dab tsi yog ib yam dab tsi uas yuav yaj tau?
Tej yam xws li ntsev, suab thaj thiab kas fes yaj hauv dej. Lawv yog soluble . Lawv feem ntau yaj sai dua thiab zoo dua hauv dej sov lossis dej kub. Kua txob thiab xuab zeb yog insoluble, lawv yuav tsis yog yaj txawm nyob hauv dej kub.
Tom qab, lo lus nug yog, dab tsi dissolving zoo li? Cov piv txwv feem ntau ntawm yaj koom nrog ib qho khoom thiab ua kua, feem ntau yog dej. Thaum ib tug khov yaj cov khoom (solute) thiab cov kua (solvent) tsim ib tug heev intimate sib tov hu ua ib tug tov. Tsuas yog cov khoom yog xim nws yuav tsis yog ua pom thiab kev daws teeb meem tsuas yog zoo li cov kua pib.
Hais txog qhov no, cov piv txwv ntawm cov tshuaj soluble yog dab tsi?
Piv txwv ntawm qee cov khoom Soluble yog:
- Ntsev hauv dej.
- Qab zib hauv dej.
- Cov pa roj carbon dioxide hauv dej.
- Glucose hauv dej.
- Oxygen hauv dej.
- sulfuric acid nyob rau hauv dej.
- Hydrochloric acid hauv dej.
- Sodium hydroxide hauv dej.
Dab tsi yog ob yam khoom uas yaj hauv dej?
Ob hom ntawm tshuaj yuav yaj hauv dej : ionic compounds, xws li sodium chloride (NaCl, los yog lub rooj ntsev) thiab cov tebchaw tsim los ntawm cov molecules loj dua uas muaj cov nqi them vim yog kev npaj ntawm lawv cov atoms. Ammonia (NH3) yog ib qho piv txwv ntawm hom thib ob.

Yuav ua li cas yog ib tug piv txwv ntawm ib tug electron cab kuj?
Raws li cov electrons raug xa mus los ntawm ib lub tshuab nqa hluav taws xob mus rau lwm qhov, lawv lub zog theem qis, thiab lub zog tawm. Cytochromes thiab quinones (xws li coenzyme Q) yog qee qhov piv txwv ntawm cov khoom siv hluav taws xob
Yuav ua li cas yog ib qho piv txwv ntawm kiag li xoom?
Tus xoom xoom yog sib npaug rau 0 ° K, − 459.67 ° F, lossis − 273.15 ° C. Thaum qhov kub thiab txias nce mus txog xoom, cov yam ntxwv ntawm lub cev ntawm qee yam khoom hloov pauv loj heev. Piv txwv li, qee yam khoom hloov pauv ntawm cov hluav taws xob hluav taws xob mus rau cov khoom siv hluav taws xob, thaum lwm tus hloov los ntawm cov hluav taws xob mus rau cov hluav taws xob
Yam ua piv txwv piv txwv li cas?
Ib khub xaj yog ib khub ntawm tus lej hauv ib qho kev txiav txim. Piv txwv li, (1, 2) thiab (- 4, 12) raug txiav ua khub. Qhov kev txiav txim ntawm ob tus lej tseem ceeb: (1, 2) tsis sib npaug rau (2, 1) -- (1, 2) ≠ (2, 1)
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Yuav ua li cas yog ib tug piv txwv ntawm ib tug rational naj npawb uas tsis yog ib tug tag nrho?
Tus lej "rational" yog qhov piv ntawm ob tus lej. Piv txwv li, cov hauv qab no yog cov lej rational, thiab tsis muaj leej twg yog tus lej: 1 / 2. 2 / 3
