CHEMISTRY 105 

Introductory Chemistry for the Health and Environmental Sciences

Chem 105 is intended for students who require a lab science course to fulfill the requirements for other UFV programs. It is an introductory lab course for students with a high school science background, and relates important scientific principles to the chemistry of the environment and the body. Chem 105 will satisfy part of the science requirements for a BA degree, but the course may not be used for credit by science or engineering majors. Chem 105 provides important background material for students intending to enter a variety of health sciences programs, and other programs requiring general chemistry. The course will provide students with information on the origins, scientific background, and significance of many aspects of chemistry that are met in the work-place and in every-day life.
