Qhov twg hauv qab no yuav tsum tau ntsib rau kev sib tsoo txoj kev xav ntawm cov tshuaj tiv thaiv tus nqi tuav ? - Cov reacting molecules yuav tsum sib tsoo nrog ib leeg. - Cov molecules yuav tsum sib tsoo nyob rau hauv ib qho kev taw qhia uas tuaj yeem ua rau rov kho cov atoms. - Cov reacting molecules yuav tsum sib tsoo nrog lub zog txaus.
Kuj paub, dab tsi yog 3 ntu ntawm kev sib tsoo txoj kev xav?
Muaj peb tseem ceeb ntu rau kev sib tsoo txoj kev xav , uas reacting tshuaj yuav tsum sib tsoo , uas lawv yuav tsum sib tsoo nrog lub zog txaus thiab lawv yuav tsum tau sib tsoo nrog txoj kev taw qhia kom raug.
Tsis tas li ntawd, peb cov txheej txheem twg yuav tsum tau ua yog tias muaj kev cuam tshuam ntawm ob lub reactants yuav tshwm sim? Raws li kev sib tsoo txoj kev xav, cov hauv qab no cov txheej txheem yuav tsum tau ua nyob rau hauv kev txiav txim rau ib qho tshuaj tshuaj tiv thaiv rau tshwm sim : Molecules yuav tsum sib tsoo nrog lub zog txaus, hu ua lub zog ua kom muaj zog, kom cov tshuaj lom neeg tuaj yeem tawg. Molecules yuav tsum sib tsoo nrog txoj kev taw qhia kom raug.
Tsuas yog li ntawd, kev sib tsoo txoj kev xav ntawm cov tshuaj tiv thaiv yog dab tsi?
Kev sib tsoo txoj kev xav . Kev sib tsoo txoj kev xav , kev xav siv los kwv yees tus tus nqi ntawm chemical cov tshuaj tiv thaiv , tshwj xeeb tshaj yog rau cov pa roj. Cov kev sib tsoo txoj kev xav yog nyob ntawm qhov kev xav tias rau ib tshuaj tiv thaiv kom tshwm sim nws yog tsim nyog rau cov reacting hom (atoms los yog molecules) los ua ke los yog sib tsoo nrog ib leeg.
Dab tsi yog kev sib tsoo txoj kev xav thiab nws cuam tshuam li cas rau cov kev tshwm sim?
Cov kev sib tsoo txoj kev xav hais tias chemical tshuaj tiv thaiv tsuas yog tshwm sim yog tias muaj kev sib tsoo ntawm txoj cai zog theem ntawm molecules thiab atoms. Nws ua raws li yog tias cov molecules sib tsoo ntau zaus tias qhov no yuav nce tus nqi ntawm tshuaj tiv thaiv . Qhov kub siab dua qhov ntau lub zog kinetic molecules thiab atoms muaj.

Qhov twg hauv qab no zoo tshaj plaws sawv cev rau qhov sib npaug molecular rau cov tshuaj tiv thaiv ntawm aqueous ammonia nrog sulfuric acid?
Nqe Lus Nug: Qhov Sib npaug Sib npaug rau Kev Ua Haujlwm Ntawm Aqueous Sulfuric Acid Nrog Aqueous Ammonia yog 2NH3 (aq) + H2SO4 (aq) --> (NH4) 2SO4 (aq) A
Yuav ua li cas tshwm sim rau atoms nyob rau hauv cov tshuaj tiv thaiv raws li Dalton lub atomic txoj kev xav?
Dalton's Atomic Theory Tag nrho cov atoms ntawm ib lub caij yog tib yam. Cov atoms ntawm cov ntsiab lus sib txawv sib txawv hauv qhov loj thiab loj. Cov tshuaj yog tsim los ntawm kev sib txawv ntawm cov lej sib txawv ntawm cov atoms. Cov tshuaj tiv thaiv tshuaj ua rau muaj kev hloov pauv ntawm cov atoms hauv cov reactant thiab cov khoom sib txuas
Yam dab tsi tuaj yeem hloov pauv yog tias koj xav nce tus nqi ntawm cov tshuaj tiv thaiv tshuaj?
Cov yam ntxwv uas cuam tshuam rau cov tshuaj tiv thaiv yog: thaj tsam ntawm cov khoom reactant. concentration los yog siab ntawm ib tug reactant. kub. xwm ntawm cov reactants. muaj/tsis muaj catalyst
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
