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: 2MnCO3(s)+O2(g)→2MnO2(s)+2CO2(g) In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxide: 3MnO2(s)+4Al(s)→3Mn(s)+2Al2O3(s) Write the net chemical equation for the production of manganese from manganese (II) carbonate, oxygen and aluminum. Be sure your equation is balanced.

The net chemical equation for the formation of manganese from manganese (II) carbonate, oxygen and aluminum is written above.

Explanation:

The given chemical equation follows:

Equation 1:       ( × 3)

Equation 2:       ( × 2)

As, the net chemical equation does not include manganese (IV) oxide. So, to cancel out from the net equation, we need to multiply equation 1 by (3) and equation 2 by (2)

Now, the net chemical equation becomes:

Hence, the net chemical equation for the formation of manganese from manganese (II) carbonate, oxygen and aluminum is written above.
