• Chapter 10: 50, 51, 57, 62, 63

Week 7 Problem Set and Workshop solutions can be found here.

For Week 8 Chemistry:

• Read Chapter 9 and Chapter 10.1-10.7, 10.9, 10.10
• Access Reading Response form here. See Guidelines.
• Learning Objectives:

  1. Calculate percent composition, molecular formula, and empirical formula

  2. Write balanced chemical equations, complete ionic equations, and net ionic equations to describe chemical reactions

  3. Use balanced chemical equations to determine the limiting reactant and calculate the percent yield

  4. Identify types of chemical reactions including precipitation, acid-base, and oxidation-reduction reactions.

  5. Use the solubility rules to predict if a reaction will occur between two aqueous reagents

• Krishna missed Problem Session on Thu. Nov. 12 to attend the Crossing Boundaries: Transforming STEM Education conference in Seattle. In particular, he attended a pre-conference workshop on Thursday afternoon: Workshop 1: Committing to Equity, Diversity, and Inclusive Excellence: Transformational Cultural Change for Student Success in STEM. You can find the full conference program linked at the conference website.
• While in Seattle, Krishna will attend a book launch for Responsive Teaching in Science and Mathematics, edited by his friends and colleagues Dr. Amy Robertson and Dr. Rachel Scherr.
• Krishna will discuss his experiences at the conference and book launch in class next week.

• Our Week 8 Seminar will be devoted almost exclusively to academic planning and working on Academic Statements.
• This session will be on Mon. Nov. 16 from 10:15 – 11:45 in CAL West, immediately following the weekly Quiz (and in place of Math Lab).
• Details on Pre-Seminar Assignment here.

Chemistry Lab 5: Discovery of Gas Laws including Pre-lab, Experiment Procedure, and Post-lab is available here.

The Pre-lab should be completed in your chemistry lab notebook and checked off at the beginning of Lab at 9 am on Thursday, Nov. 12th. Please read through the entire lab, including the Post-lab (Calculations), before Thursday morning.

• **Attempt all problems before Thursday Problem Session**.
• Include solutions to ALL TEXT PROBLEMS in your Problem Set Notebook; Workbook problems can stay in the Workbook.
• Submit bold underlined problems via MasteringPhysics by 9pm Sat. Nov. 14.

Math and Physics Lab Notebooks will be submitted for a spot check on Friday November 20.

• Turn in your Math and Physics Lab Notebook(s) by 5 pm Fri. Nov. 20 outside the door to Krishna’s office Lab 2 room 3255.
• Notebooks will be checked for evidence of engagement, evidence of learning, and attention to completion.
• It’s not a good use of your time to spend a lot of time catching up on old labs – the intent of the math and physics labs and the attendant learning occurs if you are working on the labs in conjunction with your work in the other parts of the program.

You can find solutions to the Week 6 Calculus, Chemistry, and Physics problem sets, plus Chemistry Workshop here.

For Week 7 Physics:

• Read Ch. 10 (skip 10.7, which you will read for Week 8).
• Access Reading Response via MasteringPhysics.
• Chapter 10 Learning Objectives
  0. (continuing objectives) I: Be able to work in and switch between verbal, pictorial, graphical, and algebraic/symbolic representations. II: Connect and apply concepts and methods of physics to other disciplines, particularly math and chemistry.
  1. State and use the Hooke’s law model for a restoring spring force, relating spring force to spring constant and displacement from equilibrium.
  2. Describe the Basic Energy Model and connect it to the First Law of Thermodynamics.
  3. a) Define kinetic energy in terms of mass and speed (magnitude of velocity); given any two of mass, speed, and kinetic energy, calculate the third. b) Define gravitational potential energy in terms of mass, gravitational field constant, and height with respect to a zero of potential energy. Given any two of gravitational potential energy, mass, and height, calculate the third. c) Define elastic potential energy in terms of spring constant and displacement from equilibrium; given any two, calculate the third. d) Define mechanical energy.
  4. State and recognize the conditions under which conservation of mechanical energy applies, and solve problems using this principle.
  5. Given a graph of an object’s potential energy and total energy vs. position, determine the object’s kinetic energy, turning points, points of stable and unstable equilibrium, and forbidden zones.

• 3.7: 15, 24, 25, 26, 27, 28, 31, 32, 33, 34, 36, 39, 41 (note: 3.7.29 replaced with 3.7.28)
• 3.10: 6, 7, 8, 9, 10, 11, 18
• (Optional) Drills: Practice as many as you need to get comfortable with the differentiation short-cuts and implicit differentiation; answers to odd-numbered problems in back of text. Section 3.7: 1 – 21 (odd).

• **Attempt all problems before Thursday Problem Session**.
• Include solutions to ALL PROBLEMS in your Problem Set Notebook.
• Submit bold underlined problems via WileyPLUS by 9pm Fri. Nov. 13.
