Chem 165 Class 16 Chapter 23: Nuclear Chemistry Suggested End-of-chapter problems for Chapter 23 (those covering today’s material in bold ) Chapter 23: 5, 6, 14, 15, 16, 17 , 18 , 20 , 23, 24 , 25 , 26 , 33, 34, 36, 55, 57, 62, 68 , 79 , 85 ARIS: Chapter 13-C: assignment due Friday (3/6) at 6:00 pm CST Objective today: 1.Discuss kinetics of nuclear decay reactions and radiodating. 2.Consider the origins of energy from nuclear reactions & nuclear binding energies. 3.Nuclear fission and fusion. Text: Chapter 23: Section 2 – 6; Next class: Chapter 14: Section 1 – 3 ARIS: Chapter 23-A: assignment due Monday (3/9) at 6:00 pm CDT Caption : Design of a nuclear power plant. Controlled nuclear reactions within the reactor core produce energy in the form of heat. This heat is carried via a liquid in a closed cycle loop to a heat exchanger, where water is heated to produce steam. This steam is then used to drive an electrical generator. ARIS: Chapter 23-B: assignment due Friday (3/13) at 6:00 pm CDT (yes—I realize this last one is due at the start of Spring Break; you can certainly complete it earlier if you prefer)

    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.
