5. For the AP Vernier Determining Enthalpy of Chemical Reaction lab, on the bottom of the back of this page, answer the following showing all work (with units, sig fig etc): a. From Pre-lab rewrite the net ionic reaction for the 1st reaction, and show all work using standard heat of formation to calculate ΔHrxn. b. From the Calorimetry of this reaction in this lab, show all work to determine the ΔHrxn by this method including dividing by moles of reactant that reacted. c. Compare the value of part a and part b. 6. From the AP Vernier Determining Enthalpy...lab, rewrite answer to Question 4, "What is the major error in this experiment and give one way to reduce this error in subsequent experiments. |
