Txhawm rau xam lub xeev oxidation rau carbon, siv cov lus qhia hauv qab no:
- Hauv daim ntawv cog lus C-H, H raug kho zoo li nws muaj oxidation xeev ntawm +1.
- Rau carbon bonded rau ntau electronegative tsis-hlau X, xws li nitrogen, oxygen, sulfur los yog halogens, txhua C-X daim ntawv cog lus yuav ua rau kom cov oxidation xeev ntawm carbon los ntawm 1.
Ib yam li ntawd, tus lej oxidation ntawm carbon yog dab tsi?
+4
Tsis tas li ntawd, koj yuav nrhiav tau oxidation li cas? Kev piav qhia:
- Tus naj npawb oxidation ntawm cov khoom dawb yog ib txwm 0.
- Tus lej oxidation ntawm monatomic ion sib npaug ntawm tus nqi ntawm ion.
- Tus naj npawb oxidation ntawm H yog +1, tab sis nws yog -1 nyob rau hauv thaum ua ke nrog tsawg electronegative ntsiab.
- Tus lej oxidation ntawm O hauv cov tebchaw feem ntau yog -2, tab sis nws yog -1 hauv peroxides.
Yog li ntawd, lub xeev oxidation ntawm CO yog dab tsi?
Nyob rau hauv nws cov compounds cobalt yuav luag ib txwm pom qhov +2 lossis +3 oxidation xeev Txawm hais tias lub xeev ntawm +4, +1, 0, thiab −1 paub.
Vim li cas oxidation ntawm cov organic tebchaw?
Oxidation yog thaum cov pa roj carbon atoms tau bonds rau oxygen, xws li yog hais hauv qhov piv txwv no. Nws ua tau kuj xa mus rau tej yam tshwm sim uas txav electrons. Oxidation yog Qhov tseeb qhov nce ntawm oxygen, uas ua rau kom muaj txiaj ntsig zoo ntawm lub atom.

Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Cov organic tebchaw tau txais lawv lub npe Li cas lo lus muaj feem xyuam rau nws lub ntsiab lus li cas?
Lo lus hais txog nws lub ntsiab lus li cas? Organic Compounds tau txais nws lub npe los ntawm tus lej ntawm cov ntawv cog lus carbon. Lo lus muaj feem xyuam rau lub ntsiab lus vim hais tias nws yuav tsum tau ua nrog bonds nyob rau hauv carbon atoms nyob rau hauv cov organic tebchaw
Yuav ua li cas koj txiav txim siab tus lej ntawm cov lej tseem ceeb hauv kev ntsuas?
Muaj peb txoj cai los txiav txim seb muaj pes tsawg tus lej tseem ceeb hauv ib tus lej: Cov lej tsis yog xoom yog qhov tseem ceeb. Ib qho xoom ntawm ob tus lej tseem ceeb yog qhov tseem ceeb. Qhov kawg xoom los yog trailing zeros nyob rau hauv tus lej zauv Xwb yog qhov tseem ceeb
Vim li cas nws tseem ceeb heev uas yuav tsum xav txog ntau yam thaum txiav txim siab cov hauv paus hniav ntawm cov kab zauv polynomial?
Piv txwv li, tus naj npawb ntawm lub sij hawm ib tug muab polynomial sib npaug muaj ib lub hauv paus ntawm ib tug muab point yog lub multiplicity ntawm lub hauv paus. Qhov kev xav ntawm ntau qhov tseem ceeb yog qhov tseem ceeb kom suav tau kom raug yam tsis muaj kev qhia tshwj xeeb (piv txwv li, ob lub hauv paus suav ob zaug). Li no cov lus qhia, ' suav nrog ntau ntau'
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
