Welcome to CH 151!

CH 151 Announcements

June 25, 2025

It was wonderful to meet you this week, and if you ever have any questions, let me know!

For Monday, June 30:

For Tuesday, July 1:

  • Turn in the "Nomenclature" lab at 8 AM, then we will do some review catch up over the previous sections. We will also start the "Density" lab... this lab will be due Monday, July 7 at 8 AM.

For Wednesday, July 2:

  • Problem Set #2 will be due; we'll talk about it first (and ask questions!) before turning it in. We will take Quiz #2 after we discuss the Problem Set, then we will do some review for the upcoming Midterm Exam (which will be Monday, July 7 at 8 AM.)

In this section we will begin to explore chemistry and what it means to be a chemist. We will discus the nomenclature (i.e. "naming") of chemistry compounds and start a discussion on how chemists manipulate the chemicals to identify and utilize them for making substances. We will also look at the importance of the periodic table and how it is arranged, and more.

By the way: you can now check your grades for CH 151 using this link. Enter your MHCC ID number just to the right of the "looking glass", then click "Go!" to see your grades.

Here's what is due during week 2 of CH 151:

  • Explore the material in Chapter 2.4. There are several tools to help you learn the material.... they include:
    • Read Chapter 2.4 in the textbook
    • Watch the Lecture video for Chapter 2.4 (found here: Chapter 2.4)
    • You can also view the PDF versions of the Lecture videos using these links: Chapter 2.4 (color / black and white).
    • You can also view the raw presentation slides in PowerPoint (Chapter 2.4) or Keynote (Chapter 2.4)
  • Start on Monday, June 30: The Nomenclature Lab. This lab is due on Tuesday, July 1 at 8 AM.)
  • Start on Tuesday, July 1: The Density Lab. This lab is due on Monday, July 7 at 8 AM.)
  • Due Wednesday, July 2 at 8 AM: Quiz #2.
    • Quizzes will consist of several 'show your work' questions that will be completed in class. You will have 30 minutes to complete the quiz. You will have access to a periodic table (provided by me) and a calculator, but no notes are allowed.
    • Sample Quiz #2 (answers) might prove helpful while preparing for this quiz.

Also, be aware that next Monday (July 7) the midterm exam for CH 151 will happening.

  • In this short four week course, the midterm comes early.... but you'll be ready for it after completing the materials in week 1 and 2 of CH 151.
  • The midterm consists of 20 multiple choice questions and 6 short answer questions. Bring your calculator; you will have access to a periodic table (which I will provide), but notes are not allowed.
  • A sample midterm exam (with answers) is available to view and practice before the actual midterm happens.

Here's a preview of what's going to be happening during Week #3:

  • We will take the midterm exam on Monday at 8 AM.
  • For Monday, start exploring the material in Chapter 7.1 (balancing chemical equations). There are several tools to help you learn the material.... they include:
    • Read Chapter 7.1 in the textbook (focus on parts relating to the balancing of chemical reactions)
    • Watch the Lecture video for Chapter 7.1, found here.
  • For Tuesday, start exploring the material in Chapter 4.4-4.6 (Lewis Structures / VSEPR). There are several tools to help you learn the material.... they include:
    • Read Chapter 4.4 - 4.6 in the textbook.
    • Watch the Lecture video for Chapter 4.4 - 4.6, found here.
  • On Tuesday, we will start the "Chemical Equations and Reaction Types" lab (which is due on Wednesday)
  • Problem Set #3 will be due on Wednesday; we will also take Quiz #3 on Wednesday.
  • On Wednesday, we will start the "Chemical Models" lab (which is due on Monday, July 14.)
