Qhov Tseem Ceeb Qhov txawv - Monoxide vs Dioxide
Cov ntsiab lus monoxide thiab dioxide yog siv nyob rau hauv lub npe ntawm oxide compounds. Ib qho oxide yog ib qho tshuaj lom neeg uas muaj tsawg kawg yog ib qho oxygen atom txuas rau lwm lub caij. Qee lub sij hawm lo lus oxide yog siv rau lub npe oxide anion (O2-). Feem ntau ntawm cov ntsiab lus tuaj yeem pom nyob rau hauv lawv daim ntawv oxide compound. Qee cov ntsiab lus tsim cov oxide sib txawv raws li lawv cov oxidation xeev. Lub sij hawm monoxide yog siv los hu ua ib qho chaw uas muaj ib qho oxygen atom txuas rau lwm lub caij. Yog li ntawd, lub sij hawm dioxide qhia tias muaj ob lub atoms oxygen. Qee lub ntsiab lus tsim oxides nrog ntau dua ob lub atoms oxygen. Qhov sib txawv tseem ceeb ntawm monoxide thiab dioxide yog cov monoxide compounds muaj ib qho oxygen atom sib txuas rau lwm lub caij thaum dioxide compounds muaj ob lub pa atoms sib txuas rau tib lub atom ntawm cov khoom sib txawv.
Monoxide yog dab tsi?
Lub sij hawm monoxide yog siv rau lub npe cov tebchaw uas muaj ib qho oxygen atom txuas rau lwm lub caij. Thaum xav txog cov anion, lo lus monoxide yog hais txog oxide anion (O2-). Txawm li cas los xij, nyob rau hauv monoxide tebchaw, tsuas yog oxygen atom tuaj yeem txuas rau ib lub atom ntawm lwm lub caij lossis ob lub atom ntawm nws, tab sis tsis ntau tshaj ob. Qhov ntawd yog vim tias oxygen atom tuaj yeem tsim tsuas yog ob daim ntawv cog lus hauv nws qhov chaw ruaj khov.
Pab pawg 1 cov ntsiab lus ntawm lub sijhawm lub sijhawm tuaj yeem muaj tsuas yog +1 lub xeev oxidation. Tab sis cov oxide anion muaj -2 oxidation xeev. Tom qab ntawd, cov monoxide ntawm pawg 1 cov ntsiab lus muaj ob lub atoms sib txuas rau tib lub atom oxygen. Tab sis nyob rau hauv cov ntaub ntawv ntawm pawg 2 ntsiab, lawv ruaj khov oxidation xeev yog +2. Tom qab ntawd, ib qho oxygen atom khi rau ib lub atom (ntawm pawg 2 lub ntsiab) los tsim cov monoxide.
Daim duab 01: Ib lub monoxide muaj ib lub atom oxygen (hauv liab) khi rau lwm lub caij.
Muaj ntau yam ntawm monoxide compounds. Qee qhov piv txwv tau muab hauv qab no.
Dioxide yog dab tsi?
Lub sij hawm dioxide yog siv rau lub npe cov tebchaw uas muaj ob lub pa oxygen atoms sib koom ua ke rau lwm lub caij. Cov tebchaw no tseem ceeb yog tsim los ntawm ob lub pa oxygen atom. Feem ntau cov sij hawm no ob lub atoms yog sib txuas rau tib lub atom (ntawm cov tshuaj sib txawv).
Daim duab 02: Ib lub dioxide muaj ob lub atom oxygen (hauv liab).
Muaj ntau yam dioxide compounds. Qee qhov piv txwv tau muab hauv qab no.
YCarbon dioxide (CO
Txawm hais tias H2O2 kuj tseem muaj ob lub atoms oxygen, nws tsis suav tias yog dioxide. Nws yog hu ua hydrogen peroxide. Yog vim li cas yog, hu rau ib tug oxide uas muaj ob lub atoms oxygen, ib tug dioxide, lub oxidation lub xeev ntawm cov pa atom nyob rau hauv lub compound yuav tsum nyob rau hauv nws ruaj khov (-2 oxidation xeev). Hauv H2O2, oxygen yog nyob rau hauv -1 oxidation xeev, yog li, nws yog hu ua peroxide.

Summary – Monoxide vs Dioxide
Monoxide thiab dioxide yog cov ntsiab lus siv rau npe sib txawv oxides raws li cov pa atoms nyob hauv lawv cov qauv tshuaj. Qhov sib txawv ntawm monoxide thiab dioxide yog tias monoxide tebchaw muaj ib qho oxygen atom sib txuas rau lwm lub caij thaum dioxide compounds muaj ob lub atoms oxygen sib txuas rau tib lub atom ntawm ib lub caij sib txawv.
