Tshuaj decomposition yog kev tawg ntawm ib qho chaw (ib txwm molecule, cov tshuaj tiv thaiv nruab nrab, thiab lwm yam) rau hauv ob lossis ntau qhov tawg. Tshuaj decomposition yog feem ntau suav thiab txhais tau tias yog qhov txawv ntawm qhov tseeb tshuaj synthesis.

Ntawm no, dab tsi yog qhov piv txwv ntawm decomposition hauv chemistry?

A decomposition Cov tshuaj tiv thaiv tshwm sim thaum ib qho reactant tawg mus rau hauv ob lossis ntau yam khoom. Qhov no tuaj yeem sawv cev los ntawm kab zauv dav dav: AB → A + B. Piv txwv ntawm decomposition Cov tshuaj tiv thaiv muaj xws li kev tawg ntawm hydrogenperoxide rau dej thiab oxygen, thiab kev tawg ntawm dej rau hydrogen thiab oxygen.

Ib sab saum toj no, puas cov ntsiab lus decompose? Ib yam khoom ntshiab ua tau be ib keeb los yog sib xyaw. Cov ntsiab lus yog cov khoom ntshiab uas ua tsis tau decomposed los ntawm cov tshuaj zoo tib yam txhais tau tias xws li cua sov, electrolysis, lossis cov tshuaj tiv thaiv. Kub, nyiaj, thiab oxygen yog piv txwv ntawm cov ntsiab lus . Cov tshuaj ua tau sib cais rau hauv lawv cov khoom tsuas yog los ntawm kev hloov tshuaj.

Ntawm no, dab tsi ua rau chemical decomposition?

Decomposition Reaction txhais A decomposition tshuaj tiv thaiv yog ib hom tshuaj cov tshuaj tiv thaiv nyob rau hauv uas ib tug compound lov downin rau ob los yog ntau tshaj cov ntsiab lus los yog tshiab compounds. Cov tshuaj tiv thaiv no feem ntau cuam tshuam nrog lub zog xws li cua sov, lub teeb, lossis hluav taws xob uas tawg sib nrug ntawm cov khoom sib txuas.

Koj puas tuaj yeem siv tshuaj decompose kub?

Tshuaj khoom Yog maj mam rhuab, Au (OH)3 decomposes rau kub (III) oxide (Au2O3) thiab tom qab ntawd kub hlau.
