4.08 Lab Report

04.08 Percent Yield: Percent Yield Lab pelt and Rubric Before You Begin: You may either sham and scatter this document into a word processing course of instruction of your survival of the fittest or print this page. 1.Create a data presentment board to record your data from the procedure. Be sure that the data control panel is neat and organized and that whole(a) measurements have the even meaningful figures and units. (3 points) Mass: Empty smasher- 24. 35g Dish w/ NaHCO3- 37.06g Dish after(prenominal) reaction- 40.06g Dish after H2O evaporated- 31.52g? 2. Write the wind up 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) instantly into devil products. (3 points)??                            HCI + NaHCO3 ? H20 + CO2 + NaCI? 3. The NaHCO3 is the limiting reactant and the HCl is th e excess reactant in this experiment. desexualize the divinatory go bad of the NaCl product, showing all of your educate 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 final result of 8.8420 grams of NaCI which is the theoretical yield.? 4. What is the certain yield of NaCl in your experiment? evince your work below. (4 points) 31.52 g - 24.35 g = 7.17 g ( Mass of NaCI after all weewee evap orated)? 5. Determine the percent yield of ! NaCl in your experiment, showing all work neatly in the situation 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 on your calculated effective yield and percent yield.
