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.

Qhov feem pua txhais li cas hauv chemistry?
Cov feem pua ntau yog ib txoj hauv kev los sawv cev qhov concentration ntawm cov khoom hauv ib qho kev sib xyaw lossis cov khoom sib xyaw hauv cov khoom sib xyaw. Cov feem pua ntau yog xam raws li qhov loj ntawm ib feem faib los ntawm tag nrho cov loj ntawm qhov sib tov, muab 100%
Qhov ntau txhais li cas hauv chemistry?
'Bulk' txhais tau hais tias cov cuab yeej ntawm ib yam khoom uas muaj qhov loj thiab qhov no yog tib lub ntsiab lus uas yog siv rau hauv qhov chaw chemistry rau cov khoom siv-gas, khoom-kua, kua-gas thiab kua-kua, raws li lawv (khoom orliquid lossis gas) yog siv nyob rau hauv loj npaum li cas (piv txwv li nyob rau hauv tej) totudy txog cov sib txawv theem
Kev taw qhia txhais li cas hauv chemistry?
Kev taw qhia hauv chemistry txhais tau hais tias thaum lub sijhawm tshuaj tiv thaiv kev sib tsoo ntawm cov atoms. Cov reactant molecules yuav tsum sib tsoo nrog kev pom zoo. Txoj kev taw qhia tseeb yog qhov uas ua kom muaj kev sib cuag ncaj qha ntawm lub atom koom nrog hauv kev sib tsoo thiab kev sib koom ua ke
Lub thickness txhais li cas hauv chemistry?
Txhais ntawm thickness. 1: ntawm txheej epitaxial, qhov kev ncua deb ntawm qhov chaw ntawm lub wafer mus rau txheej-substrate interface. [
Aqueous txhais li cas hauv chemistry?
Ib qho tshuaj aqueous yog ib qho kev daws teeb meem uas cov kuab tshuaj yog dej. Nws yog feem ntau qhia inchemical sib npaug los ntawm appending (aq) rau cov mis formula. Ib qho piv txwv ntawm cov tshuaj hydrophilic yog sodium chloride. Acids thiab bases yog aqueoussolutions, raws li ib feem ntawm lawv cov ntsiab lus Arrhenius
