1. [8 points] A side reaction in the manufacture of rayon from wood pulp is CS2 + NaOH Na2CS; + Na2CO3 + H2O How many grams of Na2CS3 are produced in the reaction of 92.5 mL of liquid CS2 (d=1.26 g/mL) and 2.78 mol NaOH? 2. (12 points] The reaction of 16.0 g CH,OH, 23.4 g NaBr, and 33.7 g H2SO4 yields 17.1 g C&H.Br in the reaction shown. What are the a. 15 points) Theoretical yield, b. 14 points) Actual yield, and c. 13 points) Percent yield of this reaction? C4H,OH + NaBr +H2SO4 C4H,Br + NaHSO4 + H2O 3. [20 points] A drop (0.05 mL) of 10,0 M HCl is spread over a sheet of thin aluminum foil. Assume that all the acid reacts with, and thus dissolves through, the foil. What will be the area, in of the cylindrical hole produced? Density of Al=2.70 g/mL; foil thickness 0.2 mm. The reaction is: Al + HCI AlCl3 + H2
