InstructiоnsYоu will hаve 120 minutes tо tаke this exаm. That includes submitting all necessary documents.Testing EnvironmentSet up your webcam to provide the best viewing angle of your working space. I should be able to see your papers, calculator (if using personal), writing utensil, and general area around you.All other devices should be out of the area. This includes headphones, air pods, or any other music/phone listening technology.If using your own graphing calculator, please show it to the camera prior to beginning the exam. If using Desmos TEST MODE App, you need to press "Start Test" and show that you're in the lockdown screen. Keep your calculator in the working area and on camera during the exam time.Testing Format20 points: Blackboard matching portion. There is no need to include any work for these problems.70 points: Handwritten problems. You will submit your answers to those questions as ONE SINGLE .PDF file at the end of the exam to the Exam 3 Problems Submission link. Please follow the included instructions carefully and make sure you stay on camera and in lockdown browser as indicated.10 points: Neatness of your work (5 points) and your testing environment video (5 points).If you use your personal calculator during the exam, please show what you did to the screen. If you used the Desmos TEST MODE App, show your phone to the screen when you are done with the length of you've been in the testing mode. This should (approximately) match the time you've spent in the lockdown browser for the exam.
Refer tо the fоllоwing bаlаnced chemicаl equation for the solvation of 1-chlorbutane, C4H9Cl, into butanol, C4H9 Part A. During this chemical reaction the concentration of C4H9Cl was continuously monitored and the following plots were constructed displaying the relationship between the concentration of C4H9Cl vs time data. Review the three scatter plots below, based on the data provided below, what is the reaction order of C4H9Cl? Final answers to this question must be included in the space below to receive credit. Part B. Provide a brief 1 sentence justification which explains how you arrived at this conclusion. Final answers to this question must be included in the space below to receive credit.
