Qhov sib txawv tseem ceeb ntawm CO thiab Co yog tias CO yog cov khoom siv tsis muaj zog uas muaj cov pa roj carbon thiab oxygen atoms, whereas Co yog hlau hu ua Cob alt.
CO thiab Co yog ob yam tshuaj sib txawv. CO yog cov xim tsis muaj xim, tsis muaj ntxhiab, thiab saj tsis qab, flammable gas uas muaj cov pa roj carbon atom thiab oxygen atom ib molecule. Cob alt yog cov khoom siv tshuaj uas muaj cov cim tshuaj Co thiab atomic tooj 27.
CO yog dab tsi?
CO yog cov tshuaj formula ntawm carbon monoxide. Nws yog xim tsis muaj xim, tsis muaj ntxhiab, tsis qab, tsis muaj roj, uas muaj cov pa roj carbon atom thiab oxygen atom rau ib lub molecule. Cov pa roj carbon monoxide tsawg dua li huab cua. Hauv cov ntsiab lus siab, carbon monoxide yog tshuaj lom rau cov tsiaj uas siv hemoglobin ua cov pa oxygen hauv cov ntshav. Tsis tas li ntawd, cov pa roj no tseem hu ua carbonous oxide, carbon (II) oxide, flue gas, thiab monoxide.

Thaum xav txog cov qauv tshuaj ntawm cov pa roj carbon monoxide, muaj ib lub pa roj carbon atom sib txuas rau ib lub atom oxygen los ntawm triple daim ntawv cog lus uas muaj ob daim ntawv cog lus pi thiab ib daim ntawv cog lus. Peb tuaj yeem txheeb xyuas cov pa roj carbon monoxide raws li qhov yooj yim tshaj plaws oxocarbon, thiab nws yog isoelectronic nrog rau lwm yam triple-bonded diatomic hom muaj kaum valence electrons, xws li. Cyanide ion.
Peb tuaj yeem npaj cov pa roj carbon monoxide siv cov oxidation ib nrab ntawm cov pa roj carbon monoxide xws li carbon dioxide. Lwm qhov chaw tseem ceeb yog coal gas. Hlau smelting kuj ua rau cov pa tshuaj lom no ua ib qho byproduct.
Cov yog dab tsi?
Lo lus Co yog hais txog cob alt hlau. Cob alt yog cov khoom siv tshuaj lom neeg uas muaj cov cim tshuaj Co thiab atomic tooj 27. Nws yog cov hlau thiab cov khoom siv d-block nyob rau hauv lub sij hawm. Cob alt yog nyob rau hauv pawg 9 thiab lub sij hawm 4. Tsis tas li ntawd, peb tuaj yeem faib nws ua cov hlau hloov pauv. Cob alt tsis tshwm sim raws li ib tug neeg hlau ntawm lub ntiaj teb crust; Tsis tas li ntawd, cob alt muaj nyob rau hauv kev sib xyaw nrog lwm cov ntsiab lus. Txawm li cas los xij, peb tuaj yeem tsim cov khoom dawb siv cov txheej txheem smelting. Cob alt yog ib qho nyuaj, lustrous xiav-grey hlau.
Daim duab 01: Cob alt
Lub atomic loj ntawm cob alt yog 58.93 amu. Peb tuaj yeem muab cov kev teeb tsa hluav taws xob ntawm cov hlau cob alt li [Ar] 3d7 4s2. Ntawm tus qauv siab thiab kub, nws yog nyob rau hauv lub solid-state. Lub melting point thiab boiling point yog 1495 ° C thiab 2927 ° C, feem. Qhov feem ntau oxidation xeev ntawm cob alt yog +2, +3 thiab +4. Nws cov qauv siv lead ua yog hexagonal kaw-packed qauv.
Ntxiv mus, cob alt yog cov khoom siv ferromagnetic. Qhov no txhais tau tias nws nyiam heev rau cov hlau nplaum. Lub ntiajteb txawj nqus tshwj xeeb ntawm cov hlau no yog 8.9, uas yog tus nqi siab heev. Halogens thiab sulfur tuaj yeem tua cov hlau no. Txawm li cas los xij, nws yog cov hlau tsis muaj zog. Peb tuaj yeem tiv thaiv nws ntawm oxidation los ntawm passivating oxide zaj duab xis.
Thaum xav txog kev tsim cov cob alt, peb tuaj yeem siv cov cob alt xws li cob altite, erythrite, glaucodot, thiab skutterudite. Txawm li cas los xij, cov tuam ntxhab feem ntau tau txais cov hlau no los ntawm kev txo cov khoom siv cob alt ntawm nickel thiab tooj liab mining.
Qhov txawv ntawm CO thiab Co yog dab tsi?
CO yog cov xim tsis muaj xim, tsis muaj ntxhiab, thiab saj tsis qab, cov pa taws uas muaj cov pa roj carbon atom thiab oxygen atom rau ib lub molecule. Cob alt yog cov khoom siv tshuaj lom neeg uas muaj cov cim tshuaj Co thiab atomic tooj 27. Yog li, qhov sib txawv tseem ceeb ntawm CO thiab Co yog tias CO yog ib qho inorganic compound uas muaj carbon thiab oxygen atoms, whereas Co yog cov hlau hu ua Cob alt.
Cov hauv qab no qhia txog qhov sib txawv ntawm CO thiab Co hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – CO vs Co
CO thiab Co yog ob yam khoom sib txawv uas muaj cov tshuaj lom neeg thiab lub cev sib txawv. Qhov sib txawv tseem ceeb ntawm CO thiab Co yog tias CO yog qhov sib xyaw ua ke uas muaj cov pa roj carbon thiab oxygen atoms, thaum Co yog hlau hu ua Cob alt.
