Week 7 Schedule: Section B

This week we will explore the behavior ideal and real gases.  We will jump ahead to chapter 10 this week and return to chapter 6 the following week.  We aim to expand our repertoire problem solving techniques to be able to convert between volumes, pressures, and temperatures of gases to moles.  We will also consider what assumptions go into the ideal gas law and when those assumptions break down.  Be sure to check out the Gas Simulator!

Homework #6 which covers the end of chapter 5 will be due Wednesday 10/17 at midnight.

Remember, exam 2 is on the horizon!  Exam 2 will take place on Thursday, 10/25, from 5pm to 7pm.

Week 6 Schedule: Section B

How are chemical reactions and energy related?  What does it mean to transfer energy? How can we get usable energy out of chemical reactions?  How can we measure these properties?

This week we will be answering these questions and more while we study Thermochemistry!

Reminder: We have two homework assignments due this week.  One on Sunday and a second on Wednesday.  After this week, we will resume our usual Wednesday due date schedule for homework.

Week 5: Section B Schedule

This week we will start by finishing chapter 4 with Oxidation and Reduction Reactions and then take a brief detour into chapter 20 to learn how to balance Redox reactions.

Then we will begin our discussion on how energy is transferred due to chemical reactions with Thermochemistry.

Reminder: First Exam is Monday, October 1st from 5pm until 7pm.

Because of the exam, you have a few extra days to do Homework Assignment #5.  That is due on Sunday, 10/7.

Exam and Review Session

Review session for first exam is on Sunday at 7 PM in Keyes 5.

Reminder: Exam 1 is Monday, Oct. 1st!  Exam Locations: Last name A-M in Keyes 105.  Last name N-Z in rooms 102 and 103, and 114.

A practice exam can be found on the “Sample Exams” section of the course website.  The relevant files are Practice Exam 1, Answers to Practice Exam 1 , and  Exam 1 from 2016.

Exam information: Exam 1 will be held on Monday, October 1st from 5:00-7:00 pm. You may work for the entire 2 hours, but the exam is expected to take most students 60 min. The exam will cover the class material from chapters 1-3, chapter 4 sections 1-2 and 5-6 (note: titrations from section 6 will not be tested), and laboratory material from experiments 1-3.  Allowed exam items are pens/pencils and a course-approved calculator. You will be provided with a periodic table. There will be an optional review session on Sunday, September 30 starting at 7:00 pm in Keyes 105.

Week 4: CH141 B Schedule

Which chemical reactions happen in our water sources like the the Belgrade Lakes? How does the fluoridation of drinking water protect tooth enamel? How do plants react when eaten by a caterpillar?   To answer these questions (and many more!) we first need to explore how chemistry happens in the aqueous phase!

This week we will learn about different types of reactions that can happen when molecules are dissolved in water.

Reminder: Our first exam will happen on Monday, Oct. 1st from 5pm -7pm. More information can be found here.  There will be an optional review session on Sunday, September 30 starting at 7:00 pm in Keyes 105.

Study Tip of the Week: Do you and your study group feel confused about a practice problem?  Bring the questions and your whole study group to office hours or email me to schedule a meeting time.  We can figure it out together!
