Cov tshuaj hloov pauv tshwm sim ntawm qib molecular, txhais tau hais tias cov atoms hauv cov molecules lossis cov tebchaw tau hloov kho los tsim cov khoom. Oxidation yog ib qho piv txwv ntawm a tshuaj hloov pauv.
Puas yog oxidation lub cev lossis tshuaj lom neeg?
Cov khoom dav dav ntawm cov teeb meem xws li xim, ntom ntom, hardness, yog cov piv txwv ntawm lub cev. Cov khoom uas piav qhia txog yuav ua li cas cov khoom hloov pauv mus rau hauv cov khoom sib txawv kiag li hu ua cov khoom siv tshuaj. Flammability thiab corrosion / oxidation kuj yog piv txwv ntawm cov khoom siv tshuaj.
Puas oxidation yog lub cev txheej txheem?
Oxidation tej zaum yuav yog txheej txheem ua raws li tus kheejlossis nws tuaj yeem pib tsim khoom. Qee lub sij hawm nws yuav pab tau, thiab qee zaus nws ua rau puas tsuaj heev. Ntawm nws cov theem pib, oxidation yog poob ntawm electrons. Nws tshwm sim thaum lub atom lossis compound poob ib lossis ntau dua electrons.
Yuav ua li cas hloov tshuaj lom neeg yog oxidation?
Ib qho oxidation-txo (redox) cov tshuaj tiv thaiv yog ib hom tshuaj tiv thaiv uas cuam tshuam nrog hloov ntawm electrons ntawm ob hom. Ib qho oxidation-txo cov tshuaj tiv thaiv yog ib qho tshuaj tiv thaiv uas cov oxidation tooj ntawm cov molecule, atom, los yog ion hloov los ntawm kev nce lossis poob ib qho hluav taws xob.
Puas yog tarnishing lub cev lossis tshuaj hloov pauv?
Tarnishing raug suav tias yog tshuaj hloov pauv.

Puas yog kev ua tau zoo yog lub cev lossis tshuaj lom neeg?
Lub cev muaj zog ntawm cov teeb meem suav nrog xim, tawv, tawv, ua kom zoo, solubility, hluav taws xob conductivity, ntom, khov cov ntsiab lus, cov ntsiab lus melting, thiab cov ntsiab lus kub. Puas yog malleability yog tshuaj lom neeg?
Puas yog denaturation yog tshuaj los yog lub cev hloov?
Denaturation ntawm ib txwm muaj protein ntau yuav piav raws li hloov pauv ntawm nws lub cev, tshuaj, lossis khoom lom neeg. Kev mob me me tuaj yeem cuam tshuam cov txheej txheem tertiary lossis quaternary, qhov hnyav hnyav tuaj yeem cuam tshuam cov saw hlau.
Puas yog lub cev tiv thaiv kab mob hauv lub cev puas tsim cov tshuaj tiv thaiv?
Lub cev tiv thaiv kab mob tau txais, nrog kev pab los ntawm lub cev hauv lub cev, tsim cov hlwb (tshuaj tiv thaiv kab mob) los tiv thaiv koj lub cev los ntawm ib tus neeg invader tshwj xeeb. Cov tshuaj tiv thaiv no yog tsim los ntawm cov hlwb hu ua B lymphocytes tom qab lub cev tau raug rau cov neeg ua phem.
Vim li cas cov tshuaj tiv thaiv combustion yog cov tshuaj tiv thaiv oxidation?
Kev sib xyaw ua ke ib txwm ua rau muaj oxygen lossis huab cua. … Hauv combustion cov tshuaj tiv thaiv oxygen yog ua ke nrog cov roj qhov chaw feem ntau carbon thiab hydrogen raws li ua rau carbon dioxide thiab dej thiab yog li qhov no yog cov tshuaj tiv thaiv oxidation.
Puas yog lub tsev muag tshuaj lossis lub tsev muag tshuaj?
Lub lub tsev muag tshuaj tuaj yeem suav tau lossis suav tsis tau. Feem ntau, feem ntau siv, cov ntsiab lus, feem ntau daim ntawv tseem yuav yog lub tsev muag tshuaj. Txawm li cas los xij, hauv cov ntsiab lus tshwj xeeb, ntau daim ntawv tuaj yeem yog cov khw muag tshuaj xws li.
