Qhov sib txawv tseem ceeb ntawm manganese oxide thiab manganese dioxide yog manganese oxide tshwm li ntsuab crystals, whereas manganese dioxide tshwm li xim av lossis xim dub.
Manganese oxide thiab manganese dioxide yog cov tshuaj tsis muaj zog oxide uas muaj manganese atoms txuas rau oxygen atoms. Ob lub tebchaw no muaj cov ntawv thov sib txawv.
Manganese Oxide yog dab tsi?
Manganese oxide yog cov tshuaj lom neeg muaj cov tshuaj formula MnO. Txawm li cas los xij, peb tuaj yeem siv lo lus no los xa mus rau ib qho oxide lossis hydroxide ntawm manganese, suav nrog manganese (II) oxide, manganese (II, III) oxide, manganese dioxide, thiab manganese (VI) oxide.
Daim duab 01: Manganese Oxide
Manganese oxide tshwm li ntsuab muaju, thiab nws yog tsim los ntawm cov nplai loj los siv los ua ib feem hauv cov chiv thiab cov khoom noj ntxiv. Zoo ib yam li lwm cov monoxides, MnO kuj tau txais cov qauv pob zeb ntsev, uas tau muab rau hauv daim duab saum toj no. Nws muaj cations thiab anions, ob qho tib si octahedrally ua haujlwm. Tsis tas li ntawd, zoo ib yam li ntau cov oxides, MnO feem ntau yog nonstoichiometric thiab tuaj yeem muaj qhov sib txawv (ntau ntawm MnO txog MnO 1.045).
Cov molar loj ntawm manganese oxide yog 70.93 g / mol. Nws muaj qhov ntom ntom ntawm 5.43 g / mol. Lub melting point yog 1945 degrees Celsius, thiab nws yog insoluble nyob rau hauv dej. Txawm li cas los xij, MnO yog soluble hauv acids. Cov qauv siv lead ua ntawm qhov sib xyaw no tuaj yeem piav qhia raws li tus qauv halite.
Manganese Dioxide yog dab tsi?
Manganese dioxide yog ib qho inorganic compound uas muaj cov tshuaj formula MnO2. Nws zoo nkaus li cov khoom siv dub-xim av thiab ib txwm tshwm sim raws li cov ntxhia pyrolusite. Nws yog lub ntsiab ore ntawm manganese, thiab nws kuj tshwm sim raws li ib feem ntawm manganese nodules.
Daim duab 02: Manganese Dioxide
Cov molar loj ntawm manganese dioxide yog 86.93 g / mol, thiab qhov ceev yog 5.026 g / cm3. Lub melting point yog hais txog 535 degrees Celsius, thiab nyob rau hauv lub kub kub, nws nyhav decompose. Txawm li cas los xij, nws yog insoluble hauv dej. Cov qauv siv lead ua ntawm manganese dioxide yog tetragonal.
Muaj ntau ntau polymorphs ntawm MnO2 nrog rau daim ntawv hydrated. Zoo ib yam li ntau lwm cov dioxides, cov khoom no crystallizes nyob rau hauv lub rutile siv lead ua qauv, muaj 3 coordinates oxide thiab octahedral hlau chaw. Cov tshuaj no yog yam ntxwv nonstoichiometric vim nws tsis muaj oxygen. Ntxiv mus, nyob rau hauv cov organic synthesis tshuaj, peb xav tau cov khoom no nyob rau hauv ib tug tshiab-npaj lub xeev. Cov qauv siv lead ua ntawm qhov sib xyaw no muaj cov qauv qhib heev uas muaj cov kab uas haum rau cov hlau atoms, suav nrog nyiaj thiab barium.
Qhov txawv ntawm Manganese Oxide thiab Manganese Dioxide yog dab tsi?
Manganese oxide thiab manganese dioxide yog ib qho tseem ceeb inorganic tebchaw tsim los ntawm oxidation ntawm manganese tshuaj ntsiab. Qhov sib txawv tseem ceeb ntawm manganese oxide thiab manganese dioxide yog manganese oxide tshwm li ntsuab crystals, whereas manganese dioxide tshwm li xim av lossis dub. Hauv manganese oxide, lub xeev oxidation ntawm manganese yog +2, thaum nyob rau hauv manganese dioxide, lub xeev oxidation ntawm manganese yog +4. Ntxiv mus, manganese oxide muaj cov qauv siv lead ua tetragonal whereas manganese dioxide muaj cov qauv siv lead ua halite.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm manganese oxide thiab manganese dioxide nyob rau hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Manganese Oxide vs Manganese Dioxide
Manganese oxide thiab manganese dioxide yog oxides ntawm manganese. Txawm li cas los xij, lo lus manganese oxide qee zaum siv los ua lub npe sib sau los xa mus rau tag nrho cov oxides thiab hydroxides ua los ntawm cov tshuaj manganese. Qhov sib txawv tseem ceeb ntawm manganese oxide thiab manganese dioxide yog manganese oxide tshwm li ntsuab crystals, whereas manganese dioxide tshwm li xim av lossis xim dub.
