Manganese (III) oxide is formed by the redox reaction in an alkaline cell: : 2 MnO2 + Zn → Mn2O3 + ZnO Manganese (III) oxide Mn2O3 must not be confused with MnOOH manganese (III) oxyhydroxide. Contrary to Mn2O3, MnOOH is a compound that decomposes at about 300 °C to form MnO2. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Manganese(III) oxide」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
