Video: Qhov twg yog ib qho piv txwv ntawm cov tshuaj tiv thaiv?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
A tshuaj tiv thaiv tshwm sim thaum ib los yog ntau tshaj tshuaj raug hloov mus rau ib qho lossis ntau dua lwm tus tshuaj . Piv txwv : hlau thiab oxygen combining ua xeb. vinegar thiab ci dej qab zib combining ua sodium acetate, carbon dioxide thiab dej.
Tsis tas li ntawd, qee qhov piv txwv ntawm cov tshuaj tiv thaiv tshuaj yog dab tsi?
Kev hloov tshuaj lom neeg
- Kev xeb ntawm hlau.
- combustion (kub) ntawm ntoo.
- Cov metabolism hauv cov zaub mov hauv lub cev.
- Sib tov cov kua qaub thiab lub hauv paus, xws li hydrochloric acid (HCl) thiab sodium hydroxide (NaOH)
- Ua noj qe.
- Digesting qab zib nrog amylase hauv qaub ncaug.
- Sib tov baking soda thiab vinegar los tsim cov pa roj carbon dioxide.
Tsis tas li ntawd, 4 hom tshuaj tiv thaiv kab mob yog dab tsi? Sawv cev ntawm plaub yam tshuaj tiv thaiv kab mob yooj yim: synthesis, decomposition , ib qho hloov pauv thiab hloov ob.
Nyob rau hauv no hais txog, dab tsi yog 5 hom tshuaj tiv thaiv piv txwv?
Lub tsib hom tshuaj tiv thaiv kab mob yog ua ke , decomposition , ib leeg-hloov, ob-hloov hloov, thiab combustion . Kev tshuaj xyuas cov reactants thiab cov khoom ntawm cov tshuaj tiv thaiv yuav tso cai rau koj tso rau hauv ib qho ntawm cov pawg no. Qee qhov kev tawm tsam yuav haum rau ntau tshaj ib pawg.
10 chemical pauv piv txwv yog dab tsi?
Kaum piv txwv ntawm kev hloov tshuaj lom neeg yog:
- Hlawv cov thee, ntoo, ntawv, kerosene, thiab lwm yam.
- Tsim cov curd los ntawm mis nyuj.
- Electrolysis ntawm dej los tsim hydrogen thiab oxygen.
- Rusting ntawm hlau.
- Kev tawg ntawm cracker.
- Ua noj ua haus.
- Kev zom zaub mov.
- Germination ntawm noob.

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
Ib qho piv txwv ntawm oxidation txo cov tshuaj tiv thaiv yog dab tsi?
Nyob rau hauv ib qho 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 piv txwv classic ntawm cov tshuaj tiv thaiv redox yog xeb. Thaum xeb tshwm sim, oxygen steals electrons los ntawm hlau. Oxygen tau txo qis thaum hlau tau oxidized
Yuav ua li cas yog ib qho piv txwv ntawm exergonic cov tshuaj tiv thaiv?
Ib qho exergonic cov tshuaj tiv thaiv yog hais txog ib qho kev tshwm sim uas lub zog tawm. Cov piv txwv ntawm exergonicreactions tshwm sim nyob rau hauv peb lub cev yog cellular respiration: C6H12O6 (glucose) + 6 O2 -> 6 CO2 + 6 H2O no cov tshuaj tiv thaiv tso tawm zog uas yog siv rau cell ua ub no
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
