Manganese commonly occurs in nature as a mineral. The extraction of manganese from the carbonite mineral rhodochrosite, involves a two-step process. In the first step, manganese (II) carbonate and oxygen react to form manganese (IV) oxide and carbon dioxide: 2 MnCO3(s) + O₂(g)-2 MnO₂ (s)+2 CO₂(g) e second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide: 3 MnO₂ (s) +4 Al(s)→-3 Mn(s) +2 Al₂O3(s) Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced. 0 ローロ X S
