Cov xwm txheej acidic
- Kev daws.
- Kauj Ruam 1: Sib cais ib nrab- cov tshuaj tiv thaiv .
- Kauj ruam 2: Tshuav cov ntsiab lus uas tsis yog O thiab H.
- Kauj ruam 3: Ntxiv H2O rau tshuav nyiaj li cas oxygen.
- Kauj Ruam 4: Tshuav hydrogen los ntawm kev ntxiv protons (H+).
- Kauj ruam 5: Tshuav tus nqi ntawm txhua qhov sib npaug nrog electrons.
- Kauj ruam 6: Scale lub cov tshuaj tiv thaiv kom cov electrons sib npaug.
Ua li no, ua li cas koj thiaj paub yog tias cov tshuaj tiv thaiv redox yog acidic lossis yooj yim?
Redox yog ib oxidation - txo cov tshuaj tiv thaiv , qhov twg nkawd ob leeg ua qhov chaw. Los ntawm tshuaj tiv thaiv mechanism, koj ua tau qhia seb "cov tshuaj tiv thaiv yog nyob rau hauv ib acidic los yog yooj yim nruab nrab" ( yog H + yog tam sim no thaum ntsuas qhov tshuaj tiv thaiv ces yog acidic nruab nrab, thiab yog OH- tam sim no ces nws yog yooj yim nruab nrab).
Koj ua li cas sib npaug cov nqi hauv cov tshuaj tiv thaiv redox?
- Kev daws.
- 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 oxygen.
- Kauj Ruam 4: Sib npaug hydrogen nrog protons.
- Kauj Ruam 5: Ntsuas tus nqi nrog e-.
- Kauj Ruam 6: Ntsuas cov tshuaj tiv thaiv kom lawv muaj qhov sib npaug ntawm cov hluav taws xob.
Ib tug kuj yuav nug, ua li cas koj sau oxidation ib nrab cov tshuaj tiv thaiv?
Phau Ntawv Qhia Txog Kev Sau Ntawv thiab Ntsuas Ib Nrab-Reaction Equations
- Txheeb xyuas cov ntsiab lus tseem ceeb uas dhau los ntawm kev hloov pauv ntawm lub xeev oxidation.
- Ntsuas tus naj npawb ntawm atoms ntawm lub ntsiab tseem ceeb ntawm ob sab.
- Ntxiv cov naj npawb tsim nyog ntawm electrons los them rau qhov kev hloov ntawm oxidation xeev.
Koj ua li cas sib npaug ntawm cov tshuaj tiv thaiv?
Rau tshuav nyiaj li cas ib qho kev sib npaug tshuaj, pib los ntawm kev sau cov lej ntawm cov atoms hauv txhua lub ntsiab lus, uas tau teev nyob rau hauv cov ntawv sau nyob ib sab ntawm txhua lub atom. Tom qab ntawd, ntxiv coefficients rau cov atoms ntawm txhua sab ntawm qhov sib npaug rau tshuav nyiaj li cas lawv nrog tib lub atoms ntawm lwm sab.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
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
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
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
