Featured Articles For Unit 0

Students interested in earning credit by editing articles should start with the featured articles.

Article #1

Chemistry is an experimental science based on observations of the structure and composition of matter, energy, and the interactions between matter and energy; Chemistry is a physical science based on laws, theories, and models. According to Zumdahl, Zumdahl, and DeCoste, chemistry is a science that deals with the materials of the universe and the changes that these materials undergo.<ref>Zumdahl, S.S., Zumdahl, S. L., DeCoste, D. J. (2006). World of Chemistry. Houghton Mifflin Company.</ref>


The Central Science
Brown, LeMay and Bursten suggested that chemistry is the central science because chemistry touches so many other subjects. For example, chemistry is interwoven with physics, biology, and earth science.


First year students will study atomic structure, chemical bonds, stoichiometry, kinetics, thermochemistry, and chemical reactions. Students will need to be organized, practice solving problems, and constantly ask questions. Additionally, students must be comfortable with math.

 

Article #2 Chemical research follows an approach to study known as the scientific method, however, "intuition and imagination play an important part in the scientific method." <ref>Pauling, L. (1988). General Chemistry, (3rd ed.). Dover.</ref>
