1 CHE 132 Final Exam Fall 2022 Form 2B Directions 1.
Place all other items besides your exam out of sight and or beneath your seat. 2.
Place your ID (face up), pencils, erasers, and a scientific calculator at your desk now. You may be asked to show proof of ID and sign an attendance sheet. 3.
On your scantron, starting from the left, write and bubble-in your (leave extra spaces blank): SBID NUMBER under IDENTIFICATION NUMBER 4.
Print your name clearly and sign. 5.
DO NOT OPEN YOUR EXAM until told to do so. 6.
All scantron forms must be submitted by10:45 am
. No extra time will be given. 7.
All answers must be entered on the Scantron answer sheet, which you must turn in. 8.
Answer sheets will not be returned, so record your answers next to each question on the exam for comparison with the answers when they are posted on Blackboard. Use the space between questions, the backs of pages, or the extra sheets for analysis and calculations. 9.
There are 28 questions on this quiz and 20 total pages. 10.
For multiple choice questions, bubble in the letter of the one choice that best completes the statement or answers the question on the scantron form. No credit will be given for multiple answers.
11.
For numerical response/short answer questions, e
nter your answers on the right-hand side of the scantron in the appropriately numbered line
. A small amount of partial credit will be given when possible.
12.
Once you open the exam, be sure you have all the pages including a Periodic Table and a sheet of equations/conversion factors. 13.
General Chemistry Policies: Possession of cell phones, smart watches, other communication devices, or any unauthorized materials during the exam will result in a grade of 0 on this exam, a report to Academic Judiciary, and a possible grade of F for the course. If you do not have an ID, note that on the sign-in sheet, and you must see Dr. Nagan the day after the exam and show her a valid ID.

The enolate of a ketone can be treated with an ester to give a diketone. Drawa mechanism for this Claisen-like reaction and explain
why an acid source is required after the reaction is complete.
For the mechanism, draw the curved arrows as needed. Include lone pairs and charges in your answer. Do not draw out any hydrogen
explicitly in your products. Do not use abbreviations such as Me or Ph.

Common brass is a copper (Cu) and zinc (Zn) alloy containing
63.0% copper by mass.
A. Write the percent Cu by mass as a conversion factor in the
boxes to the right. Include the
proper
units.
B. If you have a brass pipe that weighs 160 kilograms, how would
you determine the mass of zinc in this pipe in pounds? Write out
your steps in words or a series of calculation steps and then give
your final answer on the space below. Discuss your work with your group. Is there one way that works
better? Come up with a plan as a group for solving problems.
(1 lb = 453.6 g, 1000 g = 1 kg, 2.20 lb = 1 kg)

The compound cyclohexanol, C6H120, is a good fuel. It is a liquid at ordinary temperatures. When the liquid is burned, the reaction involved is
2 C6H120(t) + 17 02(g)→12 CO2(g) + 12 H20(g)
The standard enthalpy of formation of liquid cyclohexanol at 25 °C is -348.2 kJ mol-1; other relevant enthalpy of formatton values in kJ mol1 are:
C6H120(g) = -286.2 ; CO2(g) = -393.5 ; H20(g) = -241.8
(a) Calculate the enthalpy change in the burning of 3.000 mol liquid cyclohexanol to form gaseous products at 25°C. State explicitly whether the reaction
is endothermic or exothermic.

(b) Would more or less heat be evolved if gaseous cyclohexanol were burned…
