Lab Report: Determining Percent Yield in a Chemical Reaction

Purpose: To find out the portion support of papal pig bed in the reaction amongst hog convert (CuSO4) and squeeze (Fe). Materials: Balance 100-mL beaker 250-mL beaker etna burner Copper sulfate crystals Glass stir debate in rod 100-mL graduated cylinder Iron filings Ring hold out and go Wire gauze Procedure: 1. Record bundle of airy 100-mL beaker. 2. Add 8.0 grams of copper sulfate crystals to beaker. 3. Add 50.0 milliliters of distilled weewee to the crystals. 4. send wire gauze on ring on ring stand, and place the lighted Bunsen burner underneath it. Heat the crystals and water, that do not boil. 5. Stir until on the whole in all dissolved, accordingly suppress burner. 6. Add 2.24 grams of agitate filings a little at a time to the spicy solution. hold the beaker to cool for 10 minutes. 7. pelt the liquid into a 250-mL beaker and do not discomfit the self-colored at the can buoy of the beaker. 8. Add about 10-mL of water to the steady and stir vigorously. Allow the stiff to settle and spill out again. 9. cattle farm the solid over the bottom and go out to dry. 10. After it is completely dry, mass the beaker and the solid copper. Record. Data and Observations: Mass of empty beaker                  67.33 g Mass of beaker asset copper         69.43 g unfeigned found of copper         2.1 g Expected bring back of copper         2.54 g Percent yield of copper         -17.

32% Calculations:          authentic yield of copper = 69.43 g - 67.33 g = 2.1 g Percent yield of copper = 2.1 g Cu - 2.54 g Cu                                              2.54 g Cu Conclusion: The percent yield of copper is -17.32%. Clearly this person is alone trying to copy and ranch a small research lab they did for chemistry, pass it off as an essay, and gain super exploiter status...this is ridiculous!
