Fundamentals of Chemistry

 Fundamentals of Chemistry David Goldberg, 

 | 2006 |  | 720 pages | PDF | 14,2 MB

Designed for the one-semester preparatory chemistry course, the new, fifth edition of Fundamentals of Chemistry provides students with a solid foundation in problem solving for all the topic areas covered in a standard general chemistry course.

The author not only provides a clear consistent methodology to help students develop conceptual and quantitative problem-solving skills, but also engages students by using analogies that relate chemistry to everyday life. Students who need help with mathematical manipulations, as well as reading and writing scientific material, will find Goldberg’s text an excellent learning tool.

Chemistry, 9th Edition

Chemistry, 9th Edition

By Kenneth W. Whitten ,Raymond E. Davis ,Larry Peck ,George G. Stanley|2010|PDF|1168 Pages|30 Mb.

The ninth edition of CHEMISTRY incorporates a strong molecular reasoning focus, amplified problem-solving exercises, and innovative technological resources. This kind of reasoning helps students think at the molecular level and make connections between molecular structure and macroscopic properties. Molecular reasoning and visualization are emphasized via Molecular-Reasoning icons, chapter objectives, chapter essays, and end-of-chapter problems, and are integrated into the accompanying technology, including OWL )Online Web-based Learning) and interactive resources on the Student Companion Site.
