Reaction sequence stoichiometry
The useful metal manganese can be extracted from the mineral rhodochrosite by a two-step process. In the first step, manganese(II) carbonate and oxygen
react to form manganese(IV) oxide and carbon dioxide:
2MnCO₂ (s) + O₂(g) → 2MnO₂ (s) + 2 CO₂ (g)
In the second step, manganese(IV) oxide and aluminum react to form manganese and aluminum oxidide:
3MnO₂ (s) + 4Al(s) 3Mn(s) + 2 AL₂O₂ (s)
W
Explanation
X
Suppose the yield of the first step is 63.% and the yield of the second step is 67.%. Calculate the mass of manganese(II) carbonate required to make 4.0 kg of
manganese.
Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.
