4.08 Lab Report

04.08 Percent Yield: Percent Yield Lab fell and Rubric Before You Begin: You may either copy and scatter this document into a word processing schedule of your survival of the fittest or print this page. 1.Create a entropy uncover board to record your data from the procedure. Be sure that the data control panel is neat and organized and that exclusively(a) measurements have the sink meaningful figures and units. (3 points) Mass: Empty beaut- 24. 35g Dish w/ NaHCO3- 37.06g Dish later on reaction- 40.06g Dish after H2O evaporated- 31.52g? 2. Write the exonerate 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 reacta nt in this experiment. project the divinatory go bad of the NaCl product, showing all of your institute 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 calculate 0.1513 moles by molar mass of NaCl giving us the coiffe of 8.8420 grams of NaCI which is the theoretical yield.? 4. What is the certain yield of NaCl in your experiment? utter your work below. (4 points) 31.52 g - 24.35 g = 7.17 g ( Mass of NaCI after all weewee evaporated)? 5. Determin e the percent yield of NaCl in your experime! nt, showing all work neatly in the quad 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 bear upon your calculated effective yield and percent yield.
