For example, suppose we weigh out 0.2636 g of pure nickel metal into a crucible and heat this metal in the air so that the nickel can react with oxygen to form a nickel oxide compound. After the sample has cooled, we weigh it again and ...
Basic Chemistry gives students the problem-solving tools and techniques they need to succeed in future chemistry courses and in the work force.
The main objective in writing this text is to make the study of chemistry an engaging and a positive experience for students by relating the structure and behavior of matter to real life.
This book covers the underlying essential concepts of basic chemistry, starting with atoms and molecules and including chemical nomenclature, chemical bonding, and, chemical units and calculations.
This book contains numerous solved problems in some important areas of chemistry. The worked examples in this book will really improve students understanding in the aspect of calculations in chemistry.
EDITIONS: This book is available in paperback in 5.5" x 8.5" (portable size), 8.5" x 11" (large size), and as an eBook.
This book is designed for students of biology, molecular biology, ecology, medicine, agriculture, forestry and other professions where the knowledge of organic chemistry plays the important role.
This book can be used as a quick reference guide to the different disciplines of Chemistry: the areas covered are General, Inorganic, Organic, and Instrumental Analysis.
Explanation: Let the bond energy of O–O bond in hydrogen peroxide be BE(O–O). Total energy absorbed during bond-breaking = 2 × BE(O-O). Total energy released during bond forming = 1 × 486 = 486 kJ mol-1. Hence, DH = 2 × BE(O-O) - 486 ...
Basic Chemistry for Water and Wastewater Operators H3O+ ion concentration = 0.001 mol or 1/1,000 mol/L Reciprocal of 1/1,000 = 1,000/1 = 103 or log of 1,000 = 3 pH = 3 pH may also be defined as minus log of hydronium ion concentration ...
