Hauv cov ntsiab lus, a tshuaj tiv thaiv yog ib txoj kev uas hloov ib los yog ntau yam khoom mus rau lwm yam khoom. Tshuaj tiv thaiv pib nrog reactants thiab hloov mus rau hauv cov khoom.
Tom qab ntawd, dab tsi yog tshuaj tiv thaiv hauv kev tshawb fawb?
Tshuaj tiv thaiv , ib txheej txheem uas ib los yog ntau yam tshuaj, cov reactants, yog hloov mus rau ib los yog ntau yam khoom, cov khoom. Cov tshuaj yog ib yam tshuaj cov ntsiab lus los yog compounds. A tshuaj tiv thaiv rearranges lub constituent atoms ntawm cov reactants los tsim cov khoom sib txawv raws li cov khoom.
Tsis tas li ntawd, dab tsi yog cov khoom hauv cov tshuaj tiv thaiv? Khoom ( chemistry ) Cov khoom yog hom tsim los ntawm tshuaj tiv thaiv . Thaum lub sij hawm a tshuaj tiv thaiv reactants hloov mus rau hauv cov khoom tom qab dhau los ntawm kev hloov pauv lub zog siab. Cov txheej txheem no ua rau kev noj cov reactants.
Kuj tseem yuav paub, dab tsi yog cov tshuaj lom neeg lom neeg?
Ib qho biochemical tshuaj tiv thaiv yog kev hloov pauv ntawm ib lub molecule mus rau ib qho txawv molecule hauv ib lub cell. Biochemical cov tshuaj tiv thaiv yog kho los ntawm enzymes, uas yog lom catalysts uas tuaj yeem hloov tus nqi thiab qhov tshwj xeeb ntawm cov tshuaj cov tshuaj tiv thaiv hauv cov hlwb.
Dab tsi yog tshuaj tiv thaiv thiab nws hom?
Qhov tsib qhov yooj yim hom ntawm tshuaj tiv thaiv yog kev sib xyaw ua ke, decomposition, ib zaug hloov, hloov ob zaug, thiab combustion. Ntsuam xyuas cov reactants thiab cov khoom ntawm ib tug muab tshuaj tiv thaiv yuav tso cai rau koj muab tso rau hauv ib qho ntawm cov pawg no. Ib txhia cov tshuaj tiv thaiv yuav haum rau ntau tshaj ib qeb.

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
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
Dab tsi yog qhov sib txawv tseem ceeb ntawm tshuaj lom neeg thiab cov tshuaj tiv thaiv nuclear Lub hlwb?
(1) Cov tshuaj tiv thaiv Nuclear cuam tshuam nrog kev hloov pauv ntawm inan atom lub nucleus, feem ntau tsim cov khoom sib txawv, nrog rau kev tawm ntawm cov hluav taws xob xws liα, β thiab gamma; lwm ray. Cov tshuaj tiv thaiv tshuaj, ntawm qhov tod tes, tsuas yog muaj kev hloov pauv ntawm cov hluav taws xob thiab tsis cuam tshuam nrog kev hloov pauv hauv cov nuclei
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
