READ THIS BEFORE ENROLLING IN CHEM 1411 !!!
Before you enroll in CHEM 1411, please read this …
1. Excellent attendance is essential.
If you already expect that you will miss 3 or more class days due to health issues or personal circumstances, this is not the right semester to take Chem 1411.
2. A high school chemistry course is a course prerequisite.
If you did not take chemistry in high school or if it was a long time ago, please consider taking CHEM 1405: Introductory Chemistry instead of or before taking this course.
3. Strong math skills are needed for this course.
You will be solving many problems involving math in this course. A few sample problems are given below. If these problems are difficult for you to work, please take either MATH 0312: Intermediate Algebra or MATH 1314: College Algebra before taking this course.
4. Homework is an important part of this course and requires time outside of class.
If you have a heavy course load or work schedule for the semester, please think about how you will make time to do the homework for this class before you enroll.
5. The textbook is an essential part of this course.
Please stop by the bookstore and take a look at the textbook Chemistry by Chang, 10th edition, before enrolling in this course. If you cannot afford to buy or rent the textbook at this time, please do not enroll in this course.
Sample Problems to Assess Math Readiness
1. Convert 20.0 centimeters to inches. (1 inch = 2.54 centimeters)
2. Convert 10.0 miles/hour to meters/second. (1 mile = 1609 meters)
3. Convert 350°F to °C. ?°C = (__°F - 32°F) x (5°C/9°F)
4. Calculate the density of a substance having a mass of 8.50 grams and a volume of 9.80 milliliters.
5. If P1 = 1.1 atm, V1 = 3.0 liters, and P2 = 1.5 atm, calculate V2 using P1•V1 = P2•V2.
6. If P1 = 1.0 atm, T1 = 298 K, and T2 = 350 K, calculate P2 using P1/T1 = P2/T2.
