kev tsis sib haum xeeb , hauv chemistry, sib cais ntawm a yam khoom nyob rau hauv atom los yog ions. Kub kev tsis sib haum xeeb tshwm sim ntawm qhov kub thiab txias. Rau piv txwv , hydrogen molecules (H 2) tsis sib haum rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv a qauv ntawm hydrogen yog kev tsis sib haum xeeb hauv atoms.

Tsuas yog li ntawd, nws txhais li cas thaum ib yam dab tsi dissociates?

Kev tsis sib haum xeeb hauv chemistry thiab biochemistry yog Cov txheej txheem dav dav uas cov molecules (los yog ionic compounds xws li ntsev, los yog complexes) cais los yog faib ua me me xws li atoms, ions, los yog radicals, feem ntau nyob rau hauv ib tug reversible yam. Dissociation yog qhov opposite ntawm kev koom tes los yog recombination.

Qhov thib ob, qhov piv txwv ntawm kev sib cais yog dab tsi? Kev tsis sib haum xeeb yog ib qho kev tsis sib haum xeeb ntawm tus neeg txoj kev xav, kev nco, kev xav, kev ua lossis kev nkag siab ntawm nws yog leej twg. Piv txwv ntawm me me, common kev tsis sib haum xeeb suav nrog kev npau suav nruab hnub, txoj kev loj hypnosis lossis "tau ploj" hauv phau ntawv lossis yeeb yaj kiab, txhua yam cuam tshuam nrog "tso kov" nrog kev paub txog ib puag ncig tam sim ntawd.

Nyob rau hauv no hais txog, dab tsi yog ib tug dissociation tshuaj tiv thaiv?

A dissociation cov tshuaj tiv thaiv yog tshuaj tshuaj tiv thaiv nyob rau hauv uas ib tug compound tawg sib nrug mus rau hauv ob los yog ntau tshaj Cheebtsam. General formula rau a dissociation tshuaj tiv thaiv AB → A + B.

Yuav ua li cas molecules dissociate?

Kev tsis sib haum xeeb . Hauv electrolytic, los yog ionic, kev tsis sib haum xeeb , qhov sib ntxiv ntawm cov kuab tshuaj los yog lub zog nyob rau hauv daim ntawv ntawm tshav kub ua molecules los yog crystals ntawm cov khoom rau tawg mus rau hauv ions (hluav taws xob cov khoom ). Feem ntau kev tsis sib haum xeeb Cov tshuaj tsim ions los ntawm kev sib xyaw tshuaj nrog cov kuab tshuaj.
