Signature: Laboratory Waste Evaluation (1 pt) Laboratory waste is considered anything generated during an experiment that is disposed of down the sewer drain, thrown in the garbage, collected in a container for disposal by the UW Environmental Health & Safety department, or released into the environment. Based on the written lab procedure and your actions during the lab, list the identity and approximate amount (mass or volume) of waste that you generated while performing this experiment. 0.01 M maleic acid solution 0.01 M fumaric acid solution 0.5 L DI water 1 trough ice cubes Paper towels Draw the structural formula for pentane: H H H H H H-C-C-C-C-C-H H H H H H Draw the structural formula for diethyl ether: H H H H H-C-C-O-C-C-H H H H H H Draw the structural formula for 2-butanone: H O H H H-C-C-C-C-H H H H Draw the structural formula for 2-butanol: H OH H H H-C-C-C-C-H H H H H Note: All secti this repo except t structur formulas be typed 0.00335 0.0034 0.00345 0.0035 0.00355 0.0036 0.00365 0.0037 -1.6 -1.4 -1.2 -1 -0.8 -0.6 -0.4 -0.2 0 f(x) = -3324.6302330552x + 10.6891663624 R² = 0.9853508834 Pentane: ln Pvap (atm) vs. 1/T (K) 1/T (K) ln Pvap (atm) 0.003300 0.003350 0.003400 0.003450 0.003500 0.003550 0.003600 0.003650 0.003700 -1.6000 -1.4000 -1.2000 -1.0000 -0.8000 -0.6000 -0.4000 -0.2000 0.0000 f(x) = -3309.4663662466x + 10.7184000366 R² = 0.9995192525 Diethyl Ether: ln Pvap (atm) vs. 1/T (K) 1/T (K) ln Pvap (atm) 0.002800 0.002900 0.003000 0.003100 0.003200 0.003300 0.003400 -2.5000 -2.0000 -1.5000 -1.0000 -0.5000 0.0000 f(x) = -3810.5172284734x + 10.7061006661 R² = 0.9997986729 2-Butanone: ln Pvap (atm) vs. 1/T (K) 1/T (K) ln Pvap (atm) 0.002750 0.002800 0.002850 0.002900 0.002950 0.003000 0.003050 -2.5000 -2.0000 -1.5000 -1.0000 -0.5000 0.0000 f(x) = -6180.2744377326x + 16.6854305709 R² = 0.9976497874 2-Butanol: ln Pvap (atm) vs. 1/T (K) 1/T (K) ln Pvap (atm)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
