What chemicals are most important?
Sulfuric acid
is the world’s most important industrial chemical! In North America we produce about 50 million tons a year, mostly by burning sulfur to form sulfur dioxide which is then reacted with water.
What is health chemistry?
Chemistry for Health Sciences is
an introductory course, which is designed exclusively for Health Sciences or Pre- Nursing majors
. Basic concepts in general, organic and biological chemistry are covered. The course is designed to show the centrality of chemistry between the physical and life sciences.
How is chemistry used in hospital?
Chemistry
contributes to the preparation and use of materials for surgery
(sutures, artificial skin, and sterile materials). The sutures used in many surgeries today do not have to be removed, because they simply dissolve in the body after a period of time.
