Essentials of General Chemistry Book

I'll give a review later

from preface
"What's new in this edition?
Kenneth Goldsby, Florida State University, has joined Raymond Chang as an author on the seventh edition of General Chemistry. Ken's background in inorganic chemistry has added insight into content and problems, and his extensive work with undergraduate students, both in the classroom and in the laboratory, reinforces Raymond's long tradition of understanding and respecting the student's view of the material as well as that of the instructor's.

Many new End-of-Chapter Problems have been added to this edition of General Chemistry, with an emphasis on interpreting graphs and solving problems based on visual information. End-of-chapter problems are organized in various ways. Each section under a topic heading begins with Review Questions followed by Problems. The Additional Problems section provides more problems not organized by section.

Many of the examples and end-of-chapter problems present extra tidbits of knowledge and enable the student to solve a chemical problem that a chemist would solve. In particular, numerous problems are based on descriptive and applied chemistry that would be found in boxed essays and later chapters of a longer text; see Problems 1.72, 4.115, 6.108, 8.108, 11.73, 13.105, 19.127. These examples and problems show students the real world of chemistry and applications of everyday life situations.

New is the creation and versatility of our Connect Chemistry system. McGraw-Hill has initiated a rigorous process to ensure high quality electronic homework. Through careful observation of real students and active instructors, we have advanced online homework to an online learning and engagement environment. The goal of Connect is to usher in a new era of meaningful online learning that balances the conceptual and quantitative problem solving aspect of this most vital disciplin.

McGraw-Hill is offering students and instructors an enhanced digital homework experience using Connect Chemistry. Each problem within Connect Chemistry carries the text problem-solving methodology and is tailored with specific hints, as well as answer-specific feedback for common incorrect answer. Each question has been accuracy checked by two or more chemistry professors. Several rounds of editorial and chemical accuracy checking, in addition to numerous instructor and student tests of all problems, ensure the accuracy of all content.
In addion to the specific hints and feedback provided for all questions, many questions allow students a chemical drawing experience that can be assessed directly within their online homework. Connect Chemistry utilizes ChemDraw, which is widely considered the ''gold standard'' of scientific drawing programs and the cornerstone application for scientists who draw and annotate molecules, reactions, and pathways. This collaboration of Connect and ChemDraw features an easy-to use, intuitive, and comprehensive course management and homework system with professional-grade drawing capabilities.

New Review of Concepts have been added to many chapters. Review of Concepts are quick conceptual exercises spread throughout the chapters to enable the student to gauge his or her understanding of the concept just presented. The answers to the Review of Concepts are availible in the Problem-Solving Workbook and on the companion website in Connect.

The entire text has been revised to improve clarity and readability, hallmark characteristics of General Chemistry. New and substantial revisions to chapters and sections include:
chapter 3 - summary of solving stoichiometry problems based on the mole method.
chapter 4 - new Example 4.4 on writing molecular, ionic, and net-ionic equations addressing common misconceptions for diprotic and triprotic acids.
chapter 9 - Example 9.11 provides insigth into drawing Lewis structures for all compounds containing elements in the third period and beyond, and addresses the controversies in drawing these structures.
chapter 19 - discussion of the increasingly important lithium-ion battery has been updated, including a new figure highlighting the role of graphene in these systems.
chapter 21 - up-to-date information on the nuclear power plant accident in Fukushima, Japan, and its implications for the nuclear power industry."Kenneth Goldsby
