A tshuaj tiv thaiv yog cov txheej txheem uas atoms tam sim no nyob rau hauv pib tshuaj rearrange muab tshiab tshuaj kev sib xyaw ua ke muaj nyob hauv cov khoom tsim los ntawm tshuaj tiv thaiv . Cov no pib tshuaj ntawm a tshuaj tiv thaiv yog hu ua cov reactants, thiab cov tshiab tshuaj qhov tshwm sim yog hu ua cov khoom.
Ua li no, dab tsi yog cov tshuaj insoluble tsim nyob rau hauv cov tshuaj tiv thaiv hu ua?
Cov insoluble tshuaj tsim thaum a tshuaj tiv thaiv yog hu ua precipitate.
Qhov thib ob, dab tsi yog qhov ntawm cov tshuaj tiv thaiv tshuaj? Muaj ob ntu rau a tshuaj tiv thaiv . Cov reactants yog cov khoom lossis cov khoom sib txuas ntawm sab laug ntawm tus xub. Cov ntsiab lus thiab cov khoom sib txuas rau sab xis ntawm tus xub yog cov khoom.
Qhov thib ob, nws hu ua dab tsi thaum tsim cov khoom tshiab?
Cov tshuaj hloov pauv tshwm sim thaum a yam khoom ua ke nrog rau lwm tus daim ntawv ib cov khoom tshiab , hu ua chemical synthesis lossis, hloov, tshuaj decomposition rau hauv ob lossis ntau qhov sib txawv tshuaj . Cov txheej txheem no yog hu ua tshuaj tiv thaiv thiab, feem ntau, tsis thim rov qab tsuas yog los ntawm cov tshuaj tiv thaiv ntxiv.
Dab tsi yog insoluble piv txwv?
" Insoluble " feem ntau txhais tau hais tias ib yam khoom tsis yaj hauv dej piv txwv suav nrog: xuab zeb, rog, ntoo, hlau, thiab yas. Thaum peb muab tso rau hauv dej thiab sim sib tov, lawv yuav tsis yaj.

Dab tsi yog tsim nyob rau hauv cov tshuaj tiv thaiv acid puag neutralization?
Cov tshuaj tiv thaiv ntawm cov kua qaub nrog lub hauv paus yog hu ua cov tshuaj tiv thaiv neutralization. Cov khoom ntawm cov tshuaj tiv thaiv no yog ntsev thiab dej. Piv txwv li, cov tshuaj tiv thaiv ntawm hydrochloric acid, HCl, nrog sodium hydroxide, NaOH, cov kev daws teeb meem tsim cov tshuaj sodium chloride, NaCl, thiab qee cov dej molecules ntxiv
Hom tshuaj twg pom nyob rau hauv cov khoom ntawm cov tshuaj tiv thaiv decomposition?
Cov tshuaj tiv thaiv decomposition tshwm sim thaum ib qho reactant tawg mus rau hauv ob lossis ntau yam khoom. Qhov no tuaj yeem sawv cev los ntawm kev sib npaug dav: AB → A + B. Cov piv txwv ntawm cov tshuaj tiv thaiv decomposition muaj xws li kev tawg ntawm hydrogen peroxide rau dej thiab oxygen, thiab kev tawg ntawm cov dej mus rau hydrogen thiab oxygen
Dab tsi yog qhov tseeb ntawm cov ntsev tsim nyob rau hauv cov tshuaj tiv thaiv neutralization ntawm hydrochloric acid nrog barium hydroxide?
Lus Nug: Dab tsi yog cov qauv ntawm cov ntsev tsim nyob rau hauv Neutralization Reaction ntawm Hydrochloric Acid Nrog Barium Hydroxide? BaCl BaCl2 BaClH BaH2 BaO
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
