Atoms yog tsis yog CREATED los yog DESTROYED thaum muaj tshuaj lom neeg . Cov kws tshawb fawb paub tias yuav tsum muaj tib tus lej ntawm atoms ntawm txhua sab ntawm lub EQUATION . Yuav kom sib npaug tshuaj sib npaug , koj yuav tsum ntxiv COEFFICIENTS nyob rau hauv pem hauv ntej ntawm lub tshuaj cov qauv hauv cov kev sib npaug . Koj ua tsis tau Ntxiv lossis hloov cov ntawv sau npe!
Tib neeg kuj nug, yuav ua li cas rau atoms hauv tshuaj tiv thaiv?
Hauv ib tshuaj tiv thaiv , cov atoms thiab cov molecules uas cuam tshuam nrog ib leeg yog hu ua reactants. Tsis muaj tshiab atoms yog tsim, thiab tsis muaj atoms puas lawm. Hauv ib tshuaj tiv thaiv , reactants tiv tauj ib leeg, bonds ntawm atoms nyob rau hauv cov reactants yog tawg, thiab atoms rearrange thiab tsim daim ntawv cog lus tshiab los ua cov khoom.
Puas muaj pes tsawg tus atoms hloov hauv cov tshuaj tiv thaiv? Txoj cai lij choj ntawm kev txuag ntawm huab hwm coj thiab lub zog ("muab ua tau tsis raug tsim los sis rhuav tshem") qhia meej tias a tshuaj hloov hloov tsis tau tus naj npawb ntawm atom hauv ib qho muab tshuaj tiv thaiv . Cov atoms tau tsuas yog rearrange kom nws ua tau yield ib tug tshiab molecule/compound tab sis lub tus naj npawb ntawm atom yuav tsum nyob tib yam.
Ib yam li ntawd, cov tshuaj tiv thaiv tshuaj twg tuaj yeem sawv cev los ntawm?
A tshuaj tiv thaiv yog ib tug rearrangement ntawm atoms nyob rau hauv uas ib los yog ntau lub tebchaw raug hloov mus rau hauv cov tebchaw tshiab. Tag nrho tshuaj lom neeg muaj peev xwm ua sawv cev los ntawm kev sib npaug thiab cov qauv. Txhua lub sij hawm uas atoms sib cais los ntawm ib leeg thiab recombine rau sib txawv ua ke ntawm atoms, peb hais a tshuaj tiv thaiv tau tshwm sim.
Vim li cas peb thiaj xav tau tshuaj loog?
Cov tshuaj tiv thaiv yog cov ntaub ntawv tshiab li cas yog ua. Thaum nuclear cov tshuaj tiv thaiv kuj tuaj yeem tsim cov teeb meem tshiab, ze li txhua yam khoom koj ntsib hauv lub neej niaj hnub yog qhov tshwm sim ntawm tshuaj kev hloov. Tshuaj tiv thaiv pab peb nkag siab txog cov khoom ntawm qhov teeb meem.

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
Puas yog dej tiv thaiv tsis muaj zog tiv thaiv?
Kev sib txhuam yog lub zog tshwm sim los ntawm ob yam khoom sib tsoo ua ke. Huab cua tsis kam thiab dej tsis kam yog hom kev sib txhuam. Lawv hu ua non- contact rog
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
