n ib chemical tshuaj tiv thaiv nruab nrab ntawm ob lub tebchaw nyob rau hauv uas qhov chaw ntawm txhua qhov sib hloov los ua ob lub tebchaw tshiab (AB + CD = AD + CB) Synonyms: ob chav decomposition , Hom metathesis: ob npaug hloov tshuaj tiv thaiv.
Ib yam li ntawd, muaj pes tsawg hom kev cuam tshuam ob npaug ntawm kev puas tsuaj?
Muaj peb hom kev hloov pauv ob zaug : nag lossis daus, neutralization thiab gas tsim. Peb yuav tham txog txhua tus thiab mus dhau ib qho piv txwv rau txhua tus.
Tsis tas li ntawd, puas yog ob chav decomposition thiab ob chav hloov chaw zoo ib yam? Qhov txawv ntawm kev hloov pauv ob npaug thiab ob chav decomposition cov tshuaj tiv thaiv yog tias cov kev hloov pauv ob npaug Cov tshuaj tiv thaiv yog tshuaj lom neeg cov tshuaj tiv thaiv nyob rau hauv uas cov khoom ntawm ob reactants pauv nrog ib leeg whereas lub ob chav decomposition cov tshuaj tiv thaiv yog ib daim ntawv ntawm kev hloov pauv ob npaug cov tshuaj tiv thaiv nyob rau hauv uas ib los yog ntau tshaj
Piv txwv li, ob chav decomposition yog dab tsi?
A ob chav decomposition Cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv uas cov ions zoo thiab tsis zoo ions hauv ob lub tebchaw hloov cov koom tes los tsim ob lub tebchaw tshiab. Ntau ob chav decomposition cov tshuaj tiv thaiv yog nag lossis daus. AgNO3(aq)+NaCl(aq) →AgCl(s)+NaNO3(aq) Lwm yam yog acid-base neutralization reactions.
Ib qho piv txwv ntawm kev hloov pauv ob zaug yog dab tsi?
A ob npaug - hloov cov tshuaj tiv thaiv tshwm sim thaum qhov chaw ntawm ob lub tebchaw ionic pauv, ua ob lub tebchaw tshiab. Ib tug yam ntxwv ntawm a ob npaug - hloov Qhov sib npaug yog tias muaj ob lub tebchaw ua reactants thiab ob lub tebchaw sib txawv raws li cov khoom. Ib piv txwv yog. CuCl 2(aq) + 2 AgNO 3(aq) → Cu(NO 3) 2(aq) + 2 AgCl(s)
Pom zoo:
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
Hom tshuaj twg pom nyob rau hauv cov khoom ntawm cov tshuaj tiv thaiv decomposition?
Cov tshuaj tiv thaiv decomposition tshwm sim thaum ib qho reactant tawg mus rau hauv ob lossis ntau yam khoom. Qhov no tuaj yeem sawv cev los ntawm kev sib npaug dav: AB → A + B. Cov piv txwv ntawm cov tshuaj tiv thaiv decomposition muaj xws li kev tawg ntawm hydrogen peroxide rau dej thiab oxygen, thiab kev tawg ntawm cov dej mus rau hydrogen thiab oxygen
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
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
