The Solvay process for the manufacture of sodium carbonate begins by passing ammonia and carbon dioxide through a solution of sodium chloride to make sodium bicarbonate and ammonium chloride. The equation for this reaction is H2O + NaCl + NH3 + CO2 → NH4Cl + NaHCO3. In the next step, sodium bicarbonate is heated to give sodium carbonate and two gases, carbon dioxide and steam 2NaHCO3 → Na2CO3 + CO2 + H2O
What is the theoretical yield of sodium carbonate, expressed in grams, if 144 g of NaCl were used in the first reaction?
If 87.6 g of Na2CO3 were obtained from the reaction described in part a, what was the percentage yield?
I got answer 130.57 g of theoratical yield
and 67% of percentage yield.
Pleas can u check me , my answer is correct or not. Thanks
130.57 g for the theoretical yield looks ok but you aren't allowed that many significant figures. You are allowed three (from the 144); therefore, I would round the theoretical yield to 131 g. For percent yield, You are allowed three and you have only two; therefore, I would recalculate that part of it and round to three places. I have 66.9%.
Determine the mass of antimony produced when 0.46g of antimony (III) oxide reacts with carbon.... (cont.)?
....occording to the following equation
Sb2O3+3C ---> 2Sb+3CO
please help me im soo lost, thank you!
