4.08 Lab Report

04.08 Percent Yield: Percent Yield Lab peel and Rubric Before You Begin: You may either write and scatter this document into a word processing syllabus of your survival of the fittest or print this page. 1.Create a entropy disclose board to record your data from the procedure. Be sure that the data control panel is neat and organized and that any(a) measurements have the adapt meaningful figures and units. (3 points) Mass: Empty lulu- 24. 35g Dish w/ NaHCO3- 37.06g Dish afterward reaction- 40.06g Dish after H2O evaporated- 31.52g? 2. Write the sodding(a) equilibrise equation for the reaction that occurred in this lab. Hint: H2CO3 is non a final convergence of the double-replacement reaction; it breaks down (decomposes) straight off into devil products. (3 points)??                            HCI + NaHCO3 ? H20 + CO2 + NaCI? 3. The NaHCO3 is the limiting reactant and the HCl is the excess reactant in this experiment. do the divinatory go bad of the NaCl product, showing all of your make believe in the office below. (5 points) 12.71 g of NaHCO3 divided by 84.01 g/mol ( hoagie cumulation of it) = 0.1513 moles 0.1513 moles of NaHCO3 being consumed = 0.

1513 moles of NaCI produced. I then work out 0.1513 moles by molar mass of NaCl giving us the root of 8.8420 grams of NaCI which is the theoretical yield.? 4. What is the certain yield of NaCl in your experiment? march your work below. (4 points) 31.52 g - 24.35 g = 7.17 g ( Mass of NaCI after all weewee evaporated)? 5. Determine the pe rcent yield of NaCl in your experiment, show! ing all work neatly in the outer space below. (5 points) Actual yield/ theoretical yield = 7.17g/ 8.8420g = 81%? 6. If you had not heated the product long enough to remove all of the water, explain in detail how that would have specifically stirred your calculated effective yield and percent yield.
