Hi online CHEM 151 students! I hope your wrap up of Unit 1 is going well, as well as your final prep for the Unit 1 exam (if you haven’t taken it already). The following is a list of reminders for the coming week as you wrap up Unit 1 and begin Unit 2.
Please don’t hesitate to contact me if you have any questions about the information below or about the course material.
Unit 1 Exam
If you haven’t already taken the Unit 1 exam, please see the info at the end of this page under Unit 1 Exam. The final day to take the Unit 1 exam is Tuesday, Jan 30, 2024.
Unit 2
The next unit is Unit 2 and it will move more into the study of chemistry, as opposed to the calculational tools emphasized in Unit 1 (especially in the Matter and measurement section). An overview of Unit 2 is provided at this link: Unit 2.
The organization of Unit 2 is similar to Unit 1 – the assignments and deadlines for Unit 2 can be seen on the Online Course Schedule – the next deadline (and the first for this Unit) is Feb 12.
Online Homework
The online homework for all three assignments in Unit 1 is due today – Monday Jan 29.
For those of you doing the honor’s homework (or interested in it), I can offer some flexibility on the deadlines – please contact me if you have interest in or questions about the Honors option.
Quiz/Class Participations
Quiz 3’s are being graded and will be returned to you shortly (if they haven’t already). There was an error in question 3. It said “How many oxygen atoms are in 1500 atoms of C6H12O6.” It should have said “How many oxygen atoms are in 1500 molecules of C6H12O6.” Because of this error, you got full credit regardless of your answer.
The correct answer to the question as it should have been written is:
1500 molecules * 6 O atoms/molecule = 9000 O atoms.

Additional Study Resources
Don’t forget to look at the Unit 1 – additional study resourcespage on this Website. It contains many resources to help you prepare for the exam. Please take a look at them. One of those resources is a practice exam. Please read more about the practice exam below:
Practice Exam
What the practice exam is:
This practice exam will be similar in length, number of questions, types of questions (multiple choice, short answer, numerical problems, etc) to your exam. The practice exam will be useful as a general review and will help you see how prepared you are. If the practice exam (without looking at your notes) is easy for you, the actual exam probably will be. If it is difficult, the actual exam probably will be.
What the practice exam is NOT:
The actual exam will NOT be the same as the practice exam with only a few numbers changed. Do NOT think that if you only study and memorize the questions on the practice exam that you will be ready for the exam because the questions will be the same.
