Manganese
Ib yam li ntawd, tib neeg nug, dab tsi hloov pauv hlau muaj ntau lub xeev oxidation?
Yog li, cov no kev hloov hlau ua tau muaj ntau heev oxidation xeev . Piv txwv li, hlau tuaj yeem pom hauv ob peb oxidation xeev xws li +2, +3, thiab +6.
Ib yam li ntawd, vim li cas cov hlau hloov pauv tau hloov pauv tau oxidation xeev? 1. Kev hloov pauv hais qhia variable xeev oxidation hauv lawv cov tebchaw vim tias muaj qhov sib txawv me me ntawm lub zog ntawm (n-1)d thiab ns orbitals. Raws li qhov tshwm sim, electrons ntawm (n-1)d orbitals nrog rau ns-orbitals koom nrog hauv kev tsim daim ntawv cog lus.
Ntawm no, cov hlau twg muaj lub xeev oxidation siab tshaj?
iridium
Vim li cas Zn CD Hg tsis yog qhov hloov pauv?
☆ ib kev hloov pauv yog cov keeb uas tau ua tsis tiav d orbitals hauv nws lub xeev hauv av lossis ib qho ntawm nws lub xeev oxidation, zn , cd thiab hg muaj tag nrho d10 configuration nyob rau hauv lawv cov av hauv av nrog rau lawv cov oxidation xeev. thiab li no, tsis txhob qhia cov cuab yeej ntawm raug kev hloov hlau.

Vim li cas tom qab kev hloov pauv kev hloov pauv tseem ceeb?
Kev hloov pauv tom qab kev txhais lus (PTMs) xws li glycosylation thiab phosphorylation ua lub luag haujlwm tseem ceeb ntawm kev ua haujlwm ntawm hemostatic proteins thiab tseem ceeb heev hauv kev teeb tsa kab mob. Xws li theem nrab hloov pauv rau cov proteins hemostatic muaj ntau yam cuam tshuam rau lawv lub peev xwm los cuam tshuam nrog lwm cov proteins
Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Thaum ib qho kev sib cais ua rau muaj kev hloov pauv hloov pauv ntawm lub ntiaj teb nce ntxiv?
Txij li thaum lub kaw lus raug cais tawm, tsis muaj cua sov tuaj yeem khiav tawm (tus txheej txheem yog li adiabatic), yog li thaum lub zog ntws tawm hauv lub cev, qhov entropy ntawm qhov system nce, piv txwv li Δ Ssys> 0. Yog li ntawd, lub entropy ntawm lub system yuav tsum tau nce rau ib tug spontaneous txheej txheem nyob rau hauv no cais system
Thaum twg cov khoom hloov pauv ncaj qha mus rau cov roj, qhov kev hloov ntawm lub xeev hu ua?
Sublimation yog tus txheej txheem ntawm transformation ncaj qha los ntawm cov khoom theem mus rau lub gaseous theem, tsis dhau los ntawm ib tug nruab nrab kua theem. Tsis tas li ntawd, nyob rau hauv qhov siab ntawm qhov siab ntawm triple point, qhov kub thiab txias yuav ua rau cov khoom hloov pauv mus rau cov roj yam tsis tau dhau los ntawm cov dej hauv cheeb tsam
Hom kev hloov pauv twg yog lub xeev hloov?
Kev hloov ntawm lub xeev yog kev hloov ntawm lub cev hauv qhov teeb meem. Lawv yog cov kev hloov pauv uas tsis hloov qhov teeb meem tshuaj pleev lossis tshuaj lom neeg. Cov txheej txheem koom nrog hauv kev hloov pauv hauv xeev suav nrog melting, khov, sublimation, deposition, condensation, thiab evaporation
