Exam 4

Wednesday 12/4
2-2:50pm
UTC 2.102A


What we provide on Exams We will provide all students with:

  • the Exam
    • cover page with periodic table and all necessary conversion factors and constants
    • actual exam - 20 multiple choice questions
  • an answer sheet - aka: bubblesheet

The cover page with the periodic table will be very similar to the one available in the Appendix of the ChemBook website (Chapter 10).

Coverage: Exam 4 covers all the material that was covered on HW's 07 and 08. ChemBook Chapters: The exam covers all of Chapter 5 on fossil fuels and thermodynamics.

Questions: The exam will have 20 multiple choice questions. This means that each question is worth 5 points. If we up that number we will let you know. We will only grade you by what is bubbled in on the answer sheet that you turn in. We will not look at your exam copy for answers, nor consider them in any way. Bubble carefully and correctly.

Bring the Following to the Exam

  • UT ID Card / picture ID
  • a pencil(s) - mechanical or wood
  • scanner only reads pencil - no ink!
  • bring eraser if you are prone to mistakes
  • bring a non-programmable, non-graphing, scientific calculator
  • we provide the rest - see previous section

DO NOT bring...

  • ink pens
  • graphing calculator
  • any type of programmable calculator
  • electronic devices - phones, earbuds, etc...
  • smart watches - put away that smart watch!

Learning Outcomes for Exam 4

Students will know...
