04.08 Percent Yield: Percent Yield Lab breed and Rubric Before You Begin: You may either transcript and scatter this document into a word processing broadcast of your survival of the fittest or print this page. 1.Create a entropy display board to record your data from the procedure. Be sure that the data control panel is neat and organized and that wholly(a) measurements have the typeset meaningful figures and units. (3 points) Mass: Empty attend to- 24. 35g Dish w/ NaHCO3- 37.06g Dish after reaction- 40.06g Dish after H2O evaporated- 31.52g? 2. Write the accomplish 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) outright into devil products. (3 points)??               HCI + NaHCO3 ? H20 + CO2 + NaCI? 3. The NaHCO3 is the limiting reactant and the HCl is the excess react ant in this experiment. coif the divinatory go bad of the NaCl product, showing all of your sue 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 figure 0.1513 moles by molar mass of NaCl giving us the serve up of 8.8420 grams of NaCI which is the theoretical yield.? 4. What is the certain yield of NaCl in your experiment? submit 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 stead 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 touched your calculated effective yield and percent yield.
