Course Length:
  • 16 Week


Hello and Welcome! 

Hi, I’m Dr. Piao, your instructor of CHEM 151. I am excited to work with you on mastering the fundamentals of chemistry so that you can launch your educational career.  CHEM 151 is a fast-paced course, so you will need to make sure you are keeping up with all the material and checking Canvas and your COC e-mail often! More detailed information about this course will be outlined in our course syllabus.

Course Description

This course is a 4.0 unit, CSU, UC transferrable course. This is a one semester preparatory course for CHEM 201 and provides intensive foundation in problem solving, basic atomic theory, stoichiometry, nomenclature, states of matter, and solution chemistry. Laboratory experiences will enforce principles learned and will familiarize students with proper handling and maintenance of gravimetric equipment. 4 units: UC, CSU transferable; UC credit limitation: Chem 110 and 151 combined, maximum credit, one course. Prerequisites for this course is Math 060, or its equivalent as determined by the COC Assessment Center.



Student Learning Outcomes (SLO’s):

At the conclusion of the course, students will be able to


1. Analyze chemical problems and chemical reactions according to stoichiometric methodology.

2. Examine the forms and states of matter, the structure of the atom, arrangement of electrons,  

     and how this relates to the organization of the periodic table.

3.  Differentiate between the essential features of covalent and ionic bonding.


1. Investigate chemical reactions with chemicals, scientific glassware, and instruments in a precise, accurate, and safe manner.

2. Analyze chemical data, including graphical manipulation, and formulate meaningful conclusions based on the chemical data.

What to Expect in this Course

Although this course will be in the distance learning modality, you will be required to meet during class time for all of lecture and lab through Zoom.  I will actually lecture through the material during our lecture zoom meetings. Our labs will consist of two general forms. I will either just provide you with the data that you normally would have collected yourself, had we been able to do the experiment (and you will perform all subsequent analysis and calculations) or you will complete virtual simulations of experiments on various free websites (so you will actually collect the data yourself, just in more of a game-type format). 

Types of Assessments

Homework, quizzes, and exams, will all be administered online. Homework will have assigned due dates, but can be completed at your own pace. Quizzes and exams will also be administered online, but I will open them for you to complete during an allotted time period, with a given time allotment. . You will have a quiz on each chapter every week and three midterm exams.

Textbook Information

recommend that you hold off on purchasing any of these course materials until after our first meeting during the first week. I will be providing you with a lot more information about the various ways you can access the materials, which may change how you want to purchase them for the semester. Briefly though, all students will be required to have:


  • Textbook: We are using the 6th Edition of Introductory Chemistry by Nivaldo Tro (although any other edition will also work for the course). Print copies of this are available in the bookstore. 
  • Lab Manual: CHEM 151 now provides a free, OER laboratory manual for students, and so no longer requires a lab-manual be purchased. All of the laboratory experiments will be posted in Canvas, and each lab, you are required to have the assigned lab accessible to you during the lab section – beginning with the very first week/class meeting!
  • Chem101: This is the program that we utilize for our online homework assignments. We will talk about how to purchase access code on the first day of class.
  • Scientific calculator: You must have a calculator capable of exponential and logarithmic functions for this class.  We can talk more about this on the first day of lecture. 

Other Relevant Course Information


This class requires a reliable computer with a high-speed internet connection. The high-speed internet connection should handle any requests that Canvas and Zoom demand of it. We will be using Canvas to assign and turn in any work as well as taking part in quizzes and exams. The ability to convert documents to pdf’s, as well as uploading said documents is also necessary.

Additional Resources


This course can be accessed on the first day of class via Canvas at Log into Canvas using your CanyonsID single sign-on:

  • CanyonsID Username is your COC student email address (Ex:
  • CanyonsID Password is your COC student email password

Please visit the Get to Know Your Online Classroom page for help logging into Canvas and for tips on using Canvas and Zoom. Canvas Chat Support is also available 24/7 for any Canvas related issues.
