Nyob rau hauv chemistry, disproportionation, qee zaum hu ua dismutation, yog cov tshuaj tiv thaiv redox hauvuas ib lub tebchaw ntawm nruab nrab oxidation xeev hloov mus rau ob lub tebchaw, ib qho siab dua thiab ib qho ntawm qis oxidation xeev..
Lub sij hawm tsis sib haum yog dab tsi?
: kev hloov pauv ntawm cov tshuaj mus rau hauv ob lossis ntau qhov sib txawv ntawm cov tshuaj feem ntau yog los ntawm kev sib xyaw oxidation thiab txo.
Dab tsi yog qhov tsis txaus ntseeg redox cov tshuaj tiv thaiv nrog piv txwv?
Cov tshuaj tiv thaiv tsis sib xws yog thaum muaj ntau hom kab mob uas muaj feem cuam tshuam nrog lub xeev oxidation tshwj xeeb tau oxidized thiab txo qis hauv ob qhov kev sib cais ib nrab, ua rau ob qho khoom lag luam uas muaj tib lub ntsiab lus. Ib qho piv txwv yooj yim yog Mn2O3 dhau los ua Mn2+ thiab MnO2.
Koj paub li cas yog qhov kev tawm tsam tsis zoo?
Hint: Cov tshuaj tiv thaiv tsis sib xws yog thaum cov khoom siv oxidized thiab txo cov khoom sib txawv. Tshuaj xyuas tus lej oxidation ntawm cov ntsiab lus hauv cov tebchaw thiab muab piv rau ob sab.
Yuav ua li cas paub yog tias nws yog lub xeev redox?
Txoj cai lij choj hais txog Oxidation States
Rau qhov yooj yim (monoatomic) ion, lub xeev oxidation yog sib npaug rau cov nqi them ntawm ion Piv txwv li, Cl – muaj oxidation xeev ntawm -1. Thaum tam sim no nyob rau hauv feem ntau cov tebchaw, hydrogen muaj oxidation lub xeev ntawm +1 thiab oxygen lub xeev oxidation ntawm −2.

Puas yog kev sib haum xeeb lossis kev sib haum xeeb?
Harmonic atherosclerosis plays ib qho tseem ceeb hauv kev txiav txim siab qhov twg cadence tshwm sim. Cadences yog qhov taw qhia muaj zog ntawm tonic lossis nruab nrab suab ntawm ib qho los yog daim. Edward Lowinsky tau hais tias lub cadence yog "
Puas muaj kev sib haum xeeb ntawm kev sib haum xeeb kev cai lij choj?
Peb qhov kev sib cog lus loj yog Kev Sib Tham Zoo Tshaj Plaws, Peb Lub Tsib Hlis Ntuj, thiab Tsev Kawm Ntawv Xaiv Tsa. Qhov Kev Pom Zoo Loj tau daws teeb meem ntawm kev sawv cev hauv tsoomfwv . Qhov kev sib haum xeeb loj ntawm Txoj Cai Lij Choj tau ua rau dab tsi?
Puas yog kev tsis sib haum xeeb thiab tsis sib haum yog tib yam?
Unconformities sawv cev rau lub sij hawm ntawm non-deposition ntawm sediment los yog active erosion ntawm strata. Nonconformity: txhim kho qhov twg sediments tau tso rau saum qhov chaw eroded ntawm igneous los yog metamorphic pob zeb. … Puas yog kev tsis sib haum xeeb thiab tsis sib haum?
Qhov twg yog qhov tsis sib haum xeeb lossis tsis sib haum?
Raws li verbs qhov txawv ntawm untangle thiab detangle yog tias untangle yog tshem tawm tangles los yog knots thaum detangle yog disentangle (tshwj xeeb yog cov plaub hau) . txhais tau tias yog dab tsi? transitive verb.: kom plam los ntawm tangles los yog entanglement:
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
