Teb thiab piav qhia: Hauv ib oxidation ib nrab cov tshuaj tiv thaiv , atom poob electron(s). Thaum ib qho tseem ceeb oxidized nws poob ib tug xov tooj ntawm electrons.
Kuj nug, dab tsi yog oxidation ib nrab cov tshuaj tiv thaiv?
A ib nrab cov tshuaj tiv thaiv yog tus oxidation los yog txo tshuaj tiv thaiv ib feem ntawm redox tshuaj tiv thaiv . A ib nrab cov tshuaj tiv thaiv yog tau los ntawm kev xav txog kev hloov hauv oxidation lub xeev ntawm tus kheej cov tshuaj koom nrog hauv redox tshuaj tiv thaiv . Ib nrab - cov tshuaj tiv thaiv feem ntau yog siv los ua ib txoj hauv kev ntsuas redox cov tshuaj tiv thaiv.
Ib yam li ntawd, oxidation thiab txo cov tshuaj tiv thaiv nrog piv txwv yog dab tsi? Kev tsim ntawm hydrogen fluoride yog ib qho piv txwv ntawm a tshuaj tiv thaiv redox . Peb tuaj yeem rhuav tshem tshuaj tiv thaiv down mus soj ntsuam cov oxidation thiab txo ntawm reactants. Hydrogen yog oxidized thiab poob ob lub electrons, yog li txhua hydrogen ua zoo. Ob lub electrons tau txais los ntawm fluorine, uas yog txo.
Tom qab ntawd, lo lus nug yog, dab tsi tshwm sim hauv qhov txo qis ib nrab cov tshuaj tiv thaiv?
A ib nrab cov tshuaj tiv thaiv yog a txo los yog oxidation tshuaj tiv thaiv . Piv txwv li, cov hauv qab no yog ib nrab tshuaj tiv thaiv . yog zoo li ib tshuaj tiv thaiv redox , Zn raug oxidized, thiab Cu2 + raug txo. Cov tshuaj tiv thaiv Redox coj qhov chaw hauv cov roj teeb ua haujlwm.
Puas yog Oxygen yog oxidizer?
Tsis muaj oxygen tsis yog ib txwm ib oxidizer los yog oxidizing tus neeg sawv cev. Rau nws kom nws yuav tsum tau txo, I.e. Nws yuav tsum tau txais electrons. Rau feem ntau oxygen Yuav luag ib txwm ua qhov no txawm li cas los xij, yog tias nws tau sib koom ua ke rau ntau lub tshuab hluav taws xob tsis zoo xws li fluorine ces oxygen ua oxidized thiab fluorine txo.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Yuav ua li cas tshwm sim rau atoms nyob rau hauv cov tshuaj tiv thaiv raws li Dalton lub atomic txoj kev xav?
Dalton's Atomic Theory Tag nrho cov atoms ntawm ib lub caij yog tib yam. Cov atoms ntawm cov ntsiab lus sib txawv sib txawv hauv qhov loj thiab loj. Cov tshuaj yog tsim los ntawm kev sib txawv ntawm cov lej sib txawv ntawm cov atoms. Cov tshuaj tiv thaiv tshuaj ua rau muaj kev hloov pauv ntawm cov atoms hauv cov reactant thiab cov khoom sib txuas
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons. Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom cov electrons sib npaug
