MnO occurs in nature as the rare mineral manganosite. It is prepared commercially by reduction of MnO2 with hydrogen, carbon monoxide or methane, e.g.: MnO2 + H2 → MnO + H2O MnO2 + CO → MnO + CO2 Upon heating to 450 °C, manganese(II) nitrate gives a mixture of oxides, MnO2-x, which can be … Meer weergeven Manganese(II) oxide is an inorganic compound with chemical formula MnO. It forms green crystals. The compound is produced on a large scale as a component of fertilizers and food additives. Meer weergeven Like many monoxides, MnO adopts the rock salt structure, where cations and anions are both octahedrally coordinated. Also like many oxides, manganese(II) oxide is often nonstoichiometric: its composition can vary from MnO to MnO1.045.
