I am finding these questions difficult..please help me...?
Q. 1. The Solvay process for the manufacture of sodium carbonate involves the following reactions: NH3(g) + H2O(l) + CO2(g) -(arrow sign) NH4HCO3(aq) NH4HCO3(aq) + NaCl(aq) -(arrow sign) NH4Cl(aq) + NaHCO3(s) 2NaHCO3(s) -(arrow sign) 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 sign) ZnCl2(aq) + H2O(l) + CO2(g) Find the a) limiting reactant b) mass of carbon dioxide c) mass of zinc chloride that could be recovered d) mass of remaining reactant NOTE: How do I show the working on my page for each of the… [cont.]

A. 2 moles NH3 and 2 moles NaCl are required to produce 1 mole Na2CO3. Calculating the atomic weights (roughly), we have NH3 = 17, NaCl = 58, and Na2CO3 = 2*23 + 12 + 3*16 = 106 x/17 = 150/106 x = 24 g NH3 x/58 = 150/106 x = 82 g NaCl 2. ZnCO3(s) + 2HCl(aq) ZnCl2(aq) + H2O(l) + CO2(g) ZnCO3 = 65.39 + 12.01 + 3*16 = 221.4 g/mole HCl = 1.008 + 35.45 = 36.458 g/mole ZnCl2 = 65.39 + 2*36.45 = 78.29 g/mole CO2 = 12.01 + 2*16 = 44.01 g/mole 0.05 mole HCl requires 0.025 moles of the others. 2.750g ZnCO3 = 2.75/221.4 = 0.01242 mole a) limiting reactant is ZnCO3 b) mass of carbon dioxide = 0.01242*44.01 = 0.54665 g c) mass of zinc chloride that could be recovered = 0.01242*78.29 = 0.97244 g d) mass of remaining reactant (0.05 - 2*0.01242)(36.458)… [cont.]
