Manganese(II,III) oxide Manganese(II,III) oxide Manganese(II,III) oxide is the chemical compound with formula MnO. Manganese is present in two oxidation states +2 and +3 and the formula is sometimes written as MnO.MnO. MnO is found in nature as the mineral hausmannite. MnO formed when any manganese oxide is heated in air above 1000 °C. Considerable research has centred on producing nanocrystalline MnO and various syntheses that involve oxidation of Mn or reduction of Mn. MnO has been found to act as a catalyst for a range of reactions e.g. the oxidation of methane and carbon monoxide; the decomposition of NO, the reduction of
Manganese, Minnesota crack through the concrete sidewalks. In the 1990s, a majority of the land was purchased. It is now privately owned and has a "no trespassing" sign posted on the gate of the southeastern part of the city. Presently, the area is consumed entirely by the growth of natural vegetation. Although the grid pattern of roads remains, the roads have either disintegrated or have been completely overtaken by grass, trees, and shrubs. The sheer height of the trees expose what has become of land once occupied by numerous buildings. Manganese is a classic example of a "ghost town." Manganese, Minnesota Manganese
