1. The Solvay process for the manufacture of sodium carbonate involves the following reactions:
NH3(g) + H2O(l) + CO2(g)-(arrow) NH4HCO3(aq)
NH4HCO3(aq) + NaCl(aq)-(arrow) NH4Cl(aq) + NaHCO3(s)
2NaHCO3(s) -(arrow) Na2CO3(s) + H2O(g) + CO2(g)
Calculate the masses of ammonia and sodium chloride required to produce 150.0kg of pure anhydrous sodium carbonate.
2. A 2.750g sample of zinc carbonate was treated with a solution containing 0.0500 moles of hydrochloric acid.
ZnCO3(s) + 2HCl(aq) -(arrow) ZnCl2(aq) + H2O(l)+ CO2(g)
Find the
a) limiting reactant
b) mass of carbon dioxide produced
c) mass of zinc chloride that could be recovered
d) mass of remaining reactant
Thanks for helping. Please show working and explain it to me if possible. Thanks so much!
