In industry, sodium carbonate is produced in two stages whose equations are as follows:

NaCl + NH3 + H2O + CO2 à NH4Cl + NaHCO3

2NaHCO3 + heat à Na2CO3 + CO2 + H2O

a) What’s the mass of sodium carbonate that can be produced from 1.0 t of sodium chloride? (Assume that the other reactants are in excess.)

Hint: Indicate clearly how you found the molar ratio. Use the two equations given to you above to make your calculations.

b) If 0.85 t of sodium carbonate is actually produced from 1.0 t of sodium chloride, what’s the theoretical yield percentage?
