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.

Introduces the key areas of chemistry required for all pharmacy degree courses and focuses on the properties and actions of drug molecules This new edition provides a clear and comprehensive overview of the various areas of general, organic, and natural products chemistry (in relation to drug molecules). Structured to enhance student understanding, it places great emphasis on the applications of key theoretical aspects of chemistry required by all pharmacy and pharmaceutical science students. This second edition particularly caters for the chemistry requirements in any ‘Integrated Pharmacy Curricula’, where science in general is meant to be taught ‘not in isolation’, but together with, and as a part of, other practice and clinical elements of the course. Chemistry for Pharmacy Students: General, Organic and Natural Product Chemistry, 2nd Edition is divided into eight chapters. It opens with an overview of the general aspects of chemistry and their importance to modern life, with emphasis on medicinal applications. The text then moves on to discuss the concepts of atomic structure and bonding and the fundamentals of stereochemistry and their significance to pharmacy in relation to drug action and toxicity. Various aspects of organic functional groups, organic reactions, heterocyclic chemistry, nucleic acids and their pharmaceutical importance are then covered in subsequent chapters, with the final chapter dealing with drug discovery and development, and natural product chemistry. Provides a student-friendly introduction to the main areas of chemistry required by pharmacy degree courses Written at a level suitable for non-chemistry students in pharmacy, but also relevant to those in life sciences, food science, and the health sciences Includes learning objectives at the beginning of each chapter Focuses on the physical properties and actions of drug molecules Chemistry for Pharmacy Students: General, Organic and Natural Product Chemistry, 2nd Edition is an essential book for pharmacy undergraduate students, and a helpful resource for those studying other subject areas within pharmaceutical sciences, biomedical sciences, cosmetic science, food sciences, and health and life sciences.
