Long considered the standard for honors and high-level mainstream general chemistry courses, PRINCIPLES OF MODERN CHEMISTRY, 7e continues to set the standard as the most modern, rigorous, and chemically and mathematically accurate text on the market. Thoroughly revised throughout to strengthen its sound atoms first approach, this authoritative text now features new and updated content, and more mathematically accurate and artistic atomic and molecular orbital art. In addition, the text is now more student friendly without compromising its rigor. End-of-chapter study aids now focus on only the most important key objectives, equations and concepts, making it easier for students to locate chapter content, while new applications to a wide range of disciplines, such as biology, chemical engineering, biochemistry, and medicine deepen students' understanding of the relevance of chemistry beyond the classroom.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ... (6) Columns for Discount on Purchases and Discount on Notes on the same side of the Cash Book; (c) Columns for Discount on Sales and Cash Sales on the debit side of the Cash Book; (d) Departmental columns in the Sales Book and in the Purchase Book. Controlling Accounts.--The addition of special columns in books of original entry makes possible the keeping of Controlling Accounts. The most common examples of such accounts are Accounts Receivable account and Accounts Payable account. These summary accounts, respectively, displace individual customers' and creditors' accounts in the Ledger. The customers' accounts are then segregated in another book called the Sales Ledger or Customers' Ledger, while the creditors' accounts are kept in the Purchase or Creditors' Ledger. The original Ledger, now much reduced in size, is called the General Ledger. The Trial Balance now refers to the accounts in the General Ledger. It is evident that the task of taking a Trial Balance is greatly simplified because so many fewer accounts are involved. A Schedule of Accounts Receivable is then prepared, consisting of the balances found in the Sales Ledger, and its total must agree with the balance of the Accounts Receivable account shown in the Trial Balance. A similar Schedule of Accounts Payable, made up of all the balances in the Purchase Ledger, is prepared, and it must agree with the balance of the Accounts Payable account of the General Ledger." The Balance Sheet.--In the more elementary part of the text, the student learned how to prepare a Statement of Assets and Liabilities for the purpose of disclosing the net capital of an enterprise. In the present chapter he was shown how to prepare a similar statement, the Balance Sheet. For all practical...

The Zumdahls' hallmark problem-solving approach and focus on conceptual development come to life in this new edition with interactive problems that promote active learning and visualization. Enhanced by a wealth of online support that is seamlessly integrated with the program, Chemistry's solid explanations, emphasis on modeling, and outstanding problem sets make both teaching and learning chemistry more meaningful and accessible than ever before. The authors emphasize a qualitative approach to chemistry in both the text and the technology program before quantitative problems are considered, helping to build comprehension. The emphasis on modeling throughout the narrative addresses the problem of rote memorization by helping students to better understand and appreciate the process of scientific development. By stressing the limitations and uses of scientific models, the authors show students how chemists think and work.

Antoine Lavoisier is considered to be the father of modern chemistry. Using experiments and careful measurements, he created a system to help chemists understand how matter behaves. He discovered and named oxygen and hydrogen, and helped set up a system to classify these and other elements. Perhaps his most famous discovery is the role oxygen plays in combustion.
