Enthalpy Change (AH) in kl/mol Please complete this worksheet and submit it to your instructor before leaving lob. Show all work. 1. Use the data collected in Part 1 to calculate the following: Mol of NaOH Heat produced (a) in kl MOSS OF NOOH Dewets 100.5759 X0,00 397) AH = heat of solution molar mass NAOH - 2.0529 +0.0513 = (0.3992 kJ 0.3992 %) 10-05 13 more more = 7.78 kJ/mole NAOH more of NAOH 40.0 g/mol 2. Use the data collected in Part 2 to calculate the following: Mol of Limiting Reactant Heat produced (9) inkl 50 ml NaOHX 2 M q=1m x Sx0+) NOOH q=103.902 X 3.98*13) 1000 9-5375.885 0.1 mol Nacht a =(5.37 kJ Enthalpy Change (AH) in kl/mol AH= 5.37 kJ/O. 1 mole 53.7 kj/mole 5 3. Use the data collected in Part 3 to calculate the following: Mol of Limiting Reactant Heat produced (q) in kJ Mass of NOOH Pellets 101.7649 X 0.00 399 KT Motor mass NaOH = 0.4060 KJ 2.115 g = 0.0528 40.0g/mol mole Enthalpy Change (AM) in kJ/mol AH = 0.4060 10.0528 = 17.69 kJ/mole) ) NooH 4. Comparison of AH values a. What was your expectation regarding the sum of the AHs for Parts 1 and 2 compared to the AH for Part 3? Explain the reason for your expectation
