1.1 Objective and scope These chapters are not intended as a treatise on range management of tropical grazing lands, nor on the agronomy of sown pastures and cultivated fodder crops, aspects of applied science that are only one stage above scientific farming and use of land. An attempt is made to present the vegetation sciences, or botany and ecology in their widest aspects, as the essential background for their application in economic land use and plant and animal husbandry. The basic thesis is that science is global, but that its practical application is restricted to specific biological and socio economic habitats. The region covered is termed the intertropical zone. This comprises the equatorial latitudes, the tropics and subtropics. It is not only that part of the globe lying between latitudes 30° north and south of the Equator, as proposed by some writers (DAVIES, W., 1960; repeated by DAVIES & SKIDMORE, 1966). Rather is it those regions of the world in which, at the lower elevations, certain families and members of the Gramineae and Leguminosae grow wild or can be cultivated. It may be a matter for discussion whether these plants in their wild communities or sown or planted crop mixtures are better indicators of a biological environment than the instruments and criteria of the meteorologists.
This new edition introduces more problem-solving strategies and new conceptual and challenge problems. Also, each Chapter Review has been enhanced with Learning Goals to reinforce the mastery of concepts for students.
This laboratory manual contains 42 experiments for the standard sequence of topics in general, organic, and biological chemistry.
The book guides students through basic chemistry problem solving with engaging visuals and a focus on developing the math skills necessary to be successful in the course.

Essential Laboratory Manual for General, Organic and Biological Chemistry
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 behaviour of matter to real life.
The eText pages look exactly like the printed text, and include powerful interactive and customization functions. This is the product access code card for MasteringChemistry with Pearson eText and does not include the actual bound book.
Health, Environmental, and Green Chemistry Notes throughout the text relate chemistry chapters to real-life topics in health, the environment, and medicine that are interesting and motivating to students.
