Barite mineral (BaSO4) is processed by heat fusion with soda ash (Na2CO3) followed by  leaching with water to produce BaCO3. The overall reaction is 
Na2CO3 + BaSO4 → Na2SO4 + BaCO3 
Mol. wt: 106 233 142 197 
The analysis shows the weight percent as: solid residue, 33.6% BaSO4 and 66.4% BaCO3; 
and soluble salts, 58.1% Na2SO4 and 41.9% Na2CO3. For the process, calculate: 
(a) The composition of the mix before fusion 
(b) The percent excess reactant 
(c) The degree of completion and extent of reaction
