Hauv ib tshuaj tiv thaiv , tsuas yog cov atoms tam sim no nyob rau hauv cov reactants tuaj yeem xaus rau hauv cov khoom. Tsis muaj cov atom tshiab tsim, thiab tsis muaj atoms raug puas tsuaj. Hauv ib tshuaj tiv thaiv , reactants sib cuag, bonds ntawm atoms nyob rau hauv lub reactants tawg, thiab atoms rearrange thiab tsim tshiab bonds los ua cov khoom.

Kuj nug, dab tsi yog qhov tseeb txog kev sib npaug tshuaj?

A tshuaj sib npaug xaus lus. Tag nrho cov atoms tam sim no thaum pib ntawm cov tshuaj tiv thaiv yog tam sim no thaum kawg. muaj tseeb . Thaum kawg ntawm a tshuaj cov tshuaj tiv thaiv, dab tsi yog tag nrho cov loj ntawm cov reactants piv rau tag nrho cov loj ntawm cov khoom?

Tsis tas li ntawd, vim li cas cov tshuaj chemical tshwm sim? Kev tshwm sim tshwm sim Thaum ob lossis ntau lub molecules cuam tshuam thiab cov molecules hloov. Bonds ntawm atoms raug tawg thiab tsim los tsim cov molecules tshiab. Thaum koj sim nkag siab tshuaj tiv thaiv , xav txog tias koj ua haujlwm nrog cov atoms.

Kuj paub, dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv yooj yim txhais?

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 constituent atoms ntawm cov reactants los tsim cov khoom sib txawv raws li cov khoom.

Dab tsi yog hom tshuaj tiv thaiv?

Lub ntsiab plaub hom ntawm cov tshuaj tiv thaiv yog kev sib txuas ncaj qha, tsom xam tshuaj tiv thaiv , ib qho kev hloov pauv, thiab kev hloov pauv ob zaug. Yog koj raug nug tsib lub ntsiab hom ntawm cov tshuaj tiv thaiv , nws yog plaub thiab ces yog acid-base los yog redox (nyob ntawm seb leej twg koj nug).
