Qhov sib txawv tseem ceeb ntawm oxygen thiab ozone yog tias cov pa oxygen yog diatomic gaseous molecule ntawm cov pa oxygen, whereas ozone yog triatomic molecule ntawm oxygen.
Oxygen gas thiab ozone yog cov paub zoo tshaj plaws ntawm cov pa oxygen. Oxygen yog ib qho roj tseem ceeb heev rau cov kab mob nyob; rau lawv ua pa. Ozone kuj tiv thaiv lub neej hauv ntiaj teb thaum nws nyob rau hauv huab cua sab saud, tab sis ntawm qhov chaw qis, nws muaj kev phom sij.
Oxygen yog dab tsi?
Oxygen yog cov khoom siv tshuaj lom neeg nrog tus lej atomic 8, uas muaj nyob hauv pawg 16 ntawm lub sijhawm teem sijhawm. Nws muaj lub teeb tsa hluav taws xob 1s2 2s2 2p4Oxygen muaj peb lub isotopes loj; 16O, 17O, 18O. Ntawm cov no, 16 O yog cov isotope tshaj plaws. Ntxiv mus, cov pa atom muaj yim electrons, thiab nws tuaj yeem tau txais ob lub electrons ntxiv los ntawm lwm lub atom los ua ib qho -2 them anion. Xwb, ob lub atoms oxygen tuaj yeem faib plaub lub electrons los ua covalent bonding uas muab cov diatomic molecule (O2).
Lub cev hnyav ntawm O2 yog 32 g mol-1 Nws yog xim tsis muaj xim, tsis muaj ntxhiab, tsis muaj roj. Muaj li ntawm 21% ntawm oxygen nyob rau hauv lub ntiaj teb huab cua. Tsis tas li ntawd, nws tsis zoo soluble hauv dej thiab yog me ntsis hnyav dua li huab cua. Oxygen kuj muaj cov khoom sib nqus. Thaum cov pa oxygen condenses ntawm -183 ° C, nws dhau los ua cov kua xim xiav.
Daim duab 01: Rau vuam lub hom phiaj, Peb xav tau Oxygen los tsim Oxy-acetylene nplaim
Tsis tas li, cov roj no ua haujlwm nrog txhua lub ntsiab lus los tsim cov oxides tshwj tsis yog cov roj inert. Yog li ntawd, nws yog ib qho zoo oxidizing tus neeg sawv cev. Oxygen yog qhov tseem ceeb hauv kev ua pa ntawm cov tsiaj muaj sia. Peb siv cov roj no hauv tsev kho mob, vuam, thiab lwm yam kev lag luam.
Ozone yog dab tsi?
Daim ntawv peb-atomic ntawm oxygen yog ozone, thiab nws yog ib hom pa oxygen. Thaum peb hnov lub npe ozone, peb xav txog txheej ozone. Lub ozone txheej tam sim no nyob rau hauv lub stratosphere ntawm qhov siab dua atmospheric theem, thiab nws absorbs teeb meem UV hluav taws xob, yog li txwv tsis pub nws mus rau lub ntiaj teb nto.
Txawm li cas los xij, ozone muaj kev phom sij nyob rau hauv qis atmospheric theem. Nws ua raws li huab cua paug (lub luag haujlwm rau photochemical smog) thiab tuaj yeem ua rau cov kab mob ua pa rau tib neeg thiab tsiaj txhu. Tsis tas li ntawd, nws ua rau cov nroj tsuag puas. Ozone tsis ruaj khov dua li cov pa oxygen, yog li ntawd; tawg rau hauv cov pa oxygen ruaj khov dua.
Daim duab 02: Hybrid Structure ntawm Ozone Gas Molecule
Cov pa roj ozone yog xim daj daj daj nrog cov ntxhiab tsw ntse. Nws yog ntau soluble hauv cov kuab tshuaj uas tsis yog-polar thiab tsawg soluble hauv dej. Ntxiv mus, ob lub pa oxygen atoms nyob rau hauv lub ozone khi ua ke nrog ob daim ntawv cog lus, thiab muaj ib tug dative daim ntawv cog lus ntawm ib tug oxygen atom nrog rau lwm cov pa atom.
Txawm li cas los xij, nws qhia txog kev ruaj khov; Yog li, qhov tseeb qauv ntawm no molecule yog ib tug hybrid qauv. Nyob ntawd, O-O daim ntawv cog lus ntev zoo ib yam ntawm peb lub atoms. Lub hauv paus oxygen atom muaj sp2 hybridization nrog ib leeg. Tsis tas li ntawd, lub ozone muaj bent geometry. Tsis tas li ntawd, nws yog ib qho polar molecule. Thiab, txij li nws yog ib tug muaj zog oxidizing neeg sawv cev, ozone yog heev reactive. Tsis tas li ntawd, cov roj no tsim los ntawm cov pa oxygen thaum muaj hnub ci.
Qhov txawv ntawm Oxygen thiab Ozone yog dab tsi?
Oxygen yog cov khoom siv tshuaj nrog tus lej atomic 8 thiab cim O thiab ozone yog cov khoom siv roj av nrog cov tshuaj formula O 3Feem ntau, thaum peb hais oxygen, peb xa mus rau cov pa oxygen. Yog li, qhov sib txawv tseem ceeb ntawm oxygen thiab ozone yog tias cov pa roj carbon dioxide yog diatomic gaseous molecule ntawm cov pa oxygen, whereas ozone yog triatomic gaseous molecule ntawm oxygen. Ntxiv mus, muaj qhov sib txawv ntawm oxygen thiab ozone hauv lawv cov xim thiab. Qhov ntawd yog; cov pa oxygen yog cov pa tsis muaj xim, tab sis ozone yog cov pa xiav daj.
Tsis tas li ntawd, lwm qhov sib txawv tseem ceeb ntawm cov pa thiab ozone yog tias cov pa roj ozone tuaj yeem ua rau muaj kev phom sij ntawm cov cua hauv qab qis tab sis, oxygen tsis yog cov pa phem. Tsis tas li ntawd, nyob rau hauv cov huab cua, cov pa oxygen tshwm sim nyob rau hauv ntau ntau dua ozone. Tsis tas li ntawd, ozone tsis ruaj khov dua li cov pa oxygen. Yog li ntawd, lub peev xwm oxidation ntawm ozone yog siab dua li cov pa oxygen.
Cov lus qhia hauv qab no ntawm qhov sib txawv ntawm cov pa thiab ozone qhia qhov sib txawv ntawm daim ntawv tabular.
Summary – Oxygen vs Ozone
Oxygen thiab ozone yog ob lub ntsiab lus tseem ceeb ntawm cov tshuaj lom neeg oxygen. Qhov sib txawv tseem ceeb ntawm cov pa thiab ozone yog tias cov pa oxygen yog ib qho diatomic gaseous molecule ntawm cov pa oxygen, whereas lub ozone yog triatomic molecule ntawm oxygen.
