Über diesen Kurs

This is an introductory course for students with limited background in chemistry; basic concepts involved in chemical reactions, stoichiometry, the periodic table, periodic trends, nomenclature, and chemical problem solving will be emphasized with the goal of preparing students for further study in chemistry as needed for many science, health, and policy professions.....

Great Beginner Course. There are some parts where there will be frustration, but the forums are helpful. Any type of class involving math and science involves practice and work. Professor is great!

A very good course to review basic college chemistry, or to prepare for for taking a college course if High School chemistry was taken too long ago. Highly recommended!

I learned so much about Chemistry! I really did not understand it in high school since I had a first year teacher. But now I know so much. I'm going to buy the text the professor recommended at the beginning of the course.

음... 내 생각에는 화학 공동교육과정을 할 때 이 강좌의 내용을 잘 알고 있으면 도움이 많이 될거같다.

hemistry is the study of matter and energy and the interaction between them. There are many reasons to study chemistry, even if you aren't pursuing a career in science.

Chemistry is everywhere in the world around you! It's in the food you eat, clothes you wear, water you drink, medicines, air, cleaners... you name it
