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: 2MnCO3(s) + O₂(g) → In the second step, manganese (IV) oxide and aluminum react to form manganese and aluminum oxidide: 3 MnO₂ (s) + 4A1(s) 3 Mn (s) + 2 Al₂O3(s) Check 2 MnO₂ (s) + 2 CO₂ (g) Suppose the yield of the first step is 88.% and the yield of the second step is 70.%. Calculate the mass of manganese(II) carbonate required to make 1.0 kg of manganese. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits. 0 0 x10 nin 0 0.0 S Save For Later E OL A S C Submit Assignmen
