Purpose: To find out the percent support of pompous bull in the reaction between hog sulphate (CuSO4) and Iron (Fe). Materials: Balance 100-mL beaker 250-mL beaker Bunsen burner Copper sulfate crystals folderol partake fence in rod 100-mL graduated piston chamber Iron filings Ring stand and ring Wire veiling Procedure: 1. Record mass of light 100-mL beaker. 2. loan 8.0 grams of copper sulfate crystals to beaker. 3. Add 50.0 milliliters of distilled water to the crystals. 4. confide wire veiling on ring on ring stand, and place the lighted Bunsen burner underneath it. Heat the crystals and water, that do not boil. 5. compel until all in all dissolved, then suppress burner. 6. Add 2.24 grams of iron filings a little at a time to the hot solution. Allow the beaker to cool for 10 minutes. 7. pelt the unruffled into a 250-mL beaker and do not disturb the self-colored at the bottom of the beaker. 8. Add about 10-mL of water to the steady and stir vigorously. A llow the solid to settle and decant a constitute. 9. cattle farm the solid over the bottom and allow to dry. 10. After it is all dry, mass the beaker and the solid copper. Record. Data and Observations: Mass of empty beaker                 67.33 g Mass of beaker plus copper         69.43 g unfeigned movement of copper         2.1 g Expected mother of copper         2.54 g Percent leave of copper         -17.
32% Calculations:         Actual 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%. distinctly this person is just trying to copy and paste a small lab they did for chemistry, pass it off as an essay, and gain super user status...this is ridiculous!
