Ua raws li cov cai no kom sib npaug qhov sib npaug redox yooj yim:
- Sau tus oxidation thiab txo ib nrab- cov tshuaj tiv thaiv rau hom uas yog txo los yog oxidized .
- Multiply the half- cov tshuaj tiv thaiv los ntawm tus lej tsim nyog kom lawv muaj cov lej sib npaug ntawm cov hluav taws xob.
- Ntxiv ob kev sib npaug tshem tawm cov electrons.
Ntxiv mus, oxidation thiab txo qhov piv txwv yog dab tsi?
Kev txo qis yog cov txheej txheem kom tau txais ib lossis ntau dua electrons. Hauv ib oxidation - txo , los yog redox, cov tshuaj tiv thaiv, ib lub atom los yog compound yuav nyiag electrons los ntawm lwm lub atom los yog compound. Ib qho classic piv txwv ntawm cov tshuaj tiv thaiv redox yog xeb. Oxygen tau txais txo thaum hlau tau oxidized.
Kuj Paub, dab tsi ua rau oxidation? Cov players loj rau corrosion thiab oxidation yog oxygen thiab atmospheric noo noo. Nws yog cov tshuaj tiv thaiv ntawm cov hlau nto nrog cov pa oxygen uas ua rau qee cov hlau rau corrode (los yog lwm yam oxidize) thiab tsim cov oxidation los yog zoo dua lub npe hu ua hlau oxide ntawm qhov chaw.
Hauv kev hais txog qhov no, koj ua li cas txiav txim siab oxidation thiab txo qis?
Tsev
- Muab cov lej oxidation rau tag nrho cov atoms hauv qhov sib npaug.
- Sib piv cov lej oxidation los ntawm sab reactant mus rau sab khoom ntawm qhov sib npaug.
- Lub caij oxidized yog qhov uas nws oxidation naj npawb nce.
- Lub ntsiab txo yog qhov uas nws tus lej oxidation txo.
Dab tsi yog qhov piv txwv ntawm cov tshuaj tiv thaiv redox hauv lub neej niaj hnub?
Txhua hnub redox cov tshuaj tiv thaiv muaj xws li photosynthesis, ua pa, combustion thiab corrosion.

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
Koj sau cov tshuaj tiv thaiv synthesis li cas?
Summary A synthesis cov tshuaj tiv thaiv tshwm sim thaum ob los yog ntau dua reactantscombine los tsim ib yam khoom. Cov tshuaj tiv thaiv no yog sawv cev los ntawm cov kab zauv dav dav: A + B → AB. Ib qho piv txwv ntawm cov tshuaj tiv thaiv synthesis yog kev sib xyaw ntawm sodium (Na) thiab chlorine (Cl) los tsim sodium chloride (NaCl)
Cov tshuaj tiv thaiv zoo li cas thaum cov tshuaj nkag mus rau hauv cov hlab ntsha?
Cov tshuaj tiv thaiv 'systemic' tshwm sim thaum cov tshuaj nkag mus rau hauv cov hlab ntsha los ntawm daim tawv nqaij, qhov muag, qhov ncauj, lossis lub ntsws
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
