Chemistry:Manganese oxide
From HandWiki
Manganese oxide is any of a variety of manganese oxides and hydroxides.[1] These include
- Manganese(II) oxide, MnO
- Manganese(II,III) oxide, Mn3O4
- Manganese(III) oxide, Mn2O3
- Manganese dioxide, MnO2
- Manganese(VI) oxide, MnO3
- Manganese(VII) oxide, Mn2O7
Other manganese oxides include Mn5O8, Mn7O12 and Mn7O13.
