Qhov sum ntawm oxidation naj npawb ntawm tag nrho cov atoms nyob rau hauv ib tug nruab nrab compound yog 0. Y = -2. Yog li ntawd Oxidation naj npawb ntawm Carbon hauv C2H5OH yog -2.
Yog li ntawd, tus lej oxidation ntawm carbon hauv ethanol yog dab tsi?
Qhov no muab C ob tsawg dua electrons tshaj nws muaj nyob rau hauv methane yog li nws yog tsim nyog lub O. S. ntawm carbon yog -2. (Txhua H yog +1, O yog -2). Rau ethanol tus tus lej ntawm valence electrons, tom qab redistribution, ntawm C-1 yog 5 (ob ntawm txhua C-H daim ntawv cog lus thiab ib qho los ntawm C-C daim ntawv cog lus) yog li O. S. yog -1.
Dab tsi yog tus lej oxidation ntawm carbon hauv ch3cooh? Yog li ntawd, ob qho tib si carbon CH3 COJ muaj OS ntawm -3 thiab +3 feem. Spoiler - 3 ntawm 1st carbon thiab +3 ntawm 2nd Cov pa roj carbon .net oxidation naj npawb ntawm carbon nyob rau hauv lub compound yog - 0.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog oxidation tooj ntawm carbon?
Yog li tsis zoo li cov hlau, uas yuav luag ib txwm nyob hauv qhov zoo oxidation xeev , cov oxidation lub xeev ntawm carbon tuaj yeem sib txawv, los ntawm -4 (hauv CH4) txog +4 (xws li hauv CO2). Nov yog qee qhov piv txwv. (Tsis txhob hnov qab tias qhov no yog hu ua "formalism" vim yog vim li cas carbon tsis yog tiag +4 lossis -4.
Tus lej oxidation ntawm carbon atom hauv li2co3 yog dab tsi?
+4

Dab tsi yog oxidation naj npawb ntawm noble gases?
Cov ntsiab lus no tau suav tias yog cov pa roj tsis zoo kom txog rau thaum xyoo 1960, vim tias lawv cov oxidation naj npawb ntawm 0 tiv thaiv cov roj noble los ntawm kev sib txuas ua ke. Tag nrho cov pa roj carbon monoxide muaj qhov siab tshaj plaws ntawm cov khoom siv hluav taws xob hauv lawv lub plhaub sab nrauv (2 rau Helium, 8 rau tag nrho lwm tus), ua rau lawv ruaj khov
Dab tsi yog tus naj npawb ntawm subatomic hais hauv atom ntawm B11?

Nws atomic tooj yog 92 thiab nws atomic mass yog 238 (92 + 146). 2.1 Electrons, Protons, Neutrons, thiab Atoms. Element Iron Symbol Fe Number of Electrons in Txhua Plhaub Thawj 2 Thib Ob 8 Peb 14
Dab tsi yog oxidation naj npawb ntawm chlorine hauv perchloric acid?
Lub xeev oxidation ntawm chlorine hauv perchloric acid yog +7. Raws li perchloric acid yog ib qho nruab nrab, tag nrho cov oxidation naj npawb ntawm cov ntsiab lus nyob rau hauv nws yuav tsum sib npaug zos rau xoom. Raws li hydrogen txuas nrog cov hlau tsis xws li chlorine thiab oxygen, nws nqa +1 oxidation xeev
