Manganese(II) nitrate Manganese(II) nitrate Manganese(II) nitrate are the inorganic compounds with formula Mn(NO)(HO). Each formula unit is composed of one Mn cation and two NO anions and varying amounts of water. Most common is the tetrahydrate Mn(NO)·4HO, but mono- and hexahydrates are also known as well as the anhydrous compound. Some of these compounds are useful precursors to the oxides of manganese. Manganese(II) nitrate is prepared by dissolving manganese(II) oxide in nitric acid: It can also be prepared from manganese dioxide and nitrogen dioxide: On heating to 300 °C, aqueous solutions of manganese(II) nitrate thermally decompose to form MnO and NO.

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
