Hauv chemistry, disproportionation, qee zaum hu ua dismutation, yog redox cov tshuaj tiv thaiv uas ib qho kev sib txuas ntawm nruab nrab oxidation xeev hloov mus rau ob lub tebchaw, ib qho siab dua thiab ib qho ntawm qis oxidation xeev.
txhais tau li cas los ntawm cov tshuaj tiv thaiv tsis sib npaug muab piv txwv?
teb. Nyob rau hauv ib tug disproportionation cov tshuaj tiv thaiv, tib yam khoom undergoes oxidation (nce nyob rau hauv oxidation tooj) raws li zoo raws li txo (qis nyob rau hauv oxidation tooj) uas ua rau tsim ntawm ob yam khoom sib txawv. e.g. (i) Mn (VI) ua tsis ruaj tsis khov txheeb ze rau Mn (VII) thiab Mn (IV) hauv cov kua qaub
txhais tau li cas los ntawm cov tshuaj tiv thaiv tsis sib npaug Chav Kawm 11?
Tus cov tshuaj tiv thaiv uas ib qho reactant tau oxidized thiab tib reactant tau txo qisyog lub npe hu ua cov tshuaj tiv thaiv tsis sib xws. Cov tshuaj tiv thaiv tsis sib xws tseem hu ua dismutation reaction. Tib lub ntsiab yog oxidized thiab txo nyob rau hauv cov tshuaj tiv thaiv disproportionation.
Dab tsi yog qhov tsis txaus ntseeg cov tshuaj tiv thaiv nrog Piv txwv Chav 12?
Ib qho tshuaj tiv thaiv uas tib hom yog ib txhij oxidised thiab txo qis yog hu ua cov tshuaj tiv thaiv tsis sib xws. Ntawm no, peb tuaj yeem hais tias Cr hauv + 5 lub xeev oxidation undergo disproportionation rau hauv nws +6 thiab +3 xeev.
Dab tsi yog qhov kev cuam tshuam tsis txaus ntseeg muab piv txwv Chav Kawm 11?
Cov tshuaj tiv thaiv tsis sib xws yog cov tshuaj tiv thaiv uas cov khoom sib xyaw ua ke oxidized thiab txo kom muab ob yam khoom sib txawv. … Cov tshuaj tiv thaiv, 2H2O2→2H2O+O2 yog cov tshuaj tiv thaiv tsis sib xws. Ib molecule ntawm hydrogen peroxide yog oxidized rau oxygen thiab lub thib ob molecule ntawm hydrogen peroxide yog txo mus rau dej.

Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Ntawm qhov sib npaug ntawm qhov sib npaug ntawm cov reactants) thiab cov khoom) yog qhov tas li?
Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine.
Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas . Puas yog tshuaj tiv thaiv kab mob tib yam li kev tiv thaiv kab mob?
Cov tshuaj tiv thaiv puas tiv thaiv koj tsis txhob kis tus kabmob?
Cov tshuaj tiv thaiv COVID-19 muaj kev nyab xeeb thiab siv tau zoo. Tshuaj tiv thaiv tsis tuaj yeem muab rau koj COVID-19. Tej zaum koj yuav muaj kev phiv tom qab txhaj tshuaj tiv thaiv. Cov no yog qhov qub thiab yuav tsum ploj mus li ob peb hnub .
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
