COURSE DESCRIPTION:
A one-semester introductory course in basic concepts and language of chemistry for the non-science major. Fundamentals of inorganic and organic chemistry with applications to everyday life. Face-to-Face class meets for 3 hours of lecture and 2 hours of lab per week.

Foundations of Chemistry in the Laboratory, by Morris Hein and Susan Arena, 14th Edition—Custom.

  • Supplies: Scientific calculator, splash goggles, appropriate lab clothing.
    • Safety Goggles:
      • Students must purchase their own laboratory safety goggles.
      • Goggles are available in the DACC Bookstore.
      • If you already have your own, they must offer complete protection of the side of your eyes. (Look for the markings "Z87" stamped on the goggles.) Lab safety glasses are not acceptable for students.
    • Calculator:
      • Any simple scientific or graphing calculator is sufficient.
      • A calculator may only be necessary for a very small portion of this class.
    • Enclosed Shoes & Pants:
      • For lab days.
      • If you are not dressed appropriately you will not be allowed to participate.

EVALUATION:
Grading is based on a weighted percentage of five different categories with overall grade divisions at 90, 80, 70 and 60 percent. The five categories are:
  • four or more midterm tests (best three) accounting for forty percent of the course grade
  • lab reports accounting for twenty percent of the course grade
  • ten quizzes (best eight) accounting for ten percent of the course grade
  • homework assignments accounting for ten percent of the course grade and a final exam accounting for twenty percent of the course grade

Attendance is required and a student may be withdrawn from the class roster due to unexcused absences.

Laboratory work must be performed during the regularly scheduled laboratory period.

"Make-up" laboratory work at an alternate time will not be an option.

No credit will be given for laboratory reports submitted if the student was absent from that laboratory session

If a student has a valid excuse for missing a lecture or laboratory class, credit for the missed period may be arranged with instructor.

It will not be "automatic".

Notes:
All students must pass the laboratory portion of the class in order to pass the course.

The final exam will include all the material that is covered in the semester. Every student is required to take the final exam at the scheduled time. Each student must take and pass the cumulative final exam in order to pass the course.

A curve may be applied at the instructor's discretion.
