Hauv ib tshuaj tiv thaiv , cov khoom (cov ntsiab lus thiab / lossis cov khoom sib txuas) hu ua reactants raug hloov mus rau lwm yam khoom (cov khoom sib txuas thiab / lossis cov khoom) hu ua cov khoom . Koj tsis tuaj yeem hloov ib lub ntsiab rau lwm qhov hauv ib tshuaj tiv thaiv - uas tshwm sim hauv nuclear cov tshuaj tiv thaiv.
Ib yam li ntawd, nws yog nug, dab tsi yog cov khoom hauv cov tshuaj tiv thaiv?
Khoom (Chemistry) Los ntawm Wikipedia, phau ntawv dawb encyclopedia. Cov khoom yog hom tsim los ntawm tshuaj cov tshuaj tiv thaiv . Thaum muaj tshuaj lom neeg 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.
Dab tsi yog qhov txawv ntawm reactants thiab cov khoom hauv cov tshuaj tiv thaiv tshuaj? Tshuaj tiv thaiv feem ntau tshwm sim nruab nrab cov khoom uas raug xa mus rau tshuaj reactants . Thaum kawg ntawm tshuaj tiv thaiv , reactants feem ntau yog noj thiab hloov mus ua ib yam khoom tshiab. Ntawm qhov tod tes, cov khoom yog cov ntsiab lus kawg ntawm tshuaj tiv thaiv , thiab lawv raug tsim thaum kawg ntawm txoj kev.
Tsis tas li lo lus nug yog, dab tsi yog cov khoom lag luam hauv kev sib npaug tshuaj?
Chemical Equation A khoom yog ib yam khoom uas muaj nyob rau hauv qhov kawg ntawm ib tshuaj tshuaj tiv thaiv. Hauv kev sib npaug saum toj no, zinc thiab sulfur yog cov reactants uas chemically sib xyaw ua cov zinc sulfide khoom . Muaj ib txoj hauv kev sau ntawv tshuaj sib npaug.
Cov tshuaj tiv thaiv tshuaj yog dab tsi piav qhia nrog piv txwv?
A tshuaj tiv thaiv tshwm sim thaum ib los yog ntau tshaj tshuaj 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. yam kub kub los yog tawg.

Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
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
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
