ENVIRONMENTAL SOIL CHEMISTRY AN OVERVIEW

Environmental chemistry, Seventh Edition, continues much the same
organizational structure, level, and emphasis that have been developed through
preceding editions. In addition to providing updated material in the rapidly
developing area of environmental chemistry, this edition emphasizes several ma[r]

Acrylic acid (IUPAC: prop2enoic acid) is an organic compound with the formula CH2=CHCO2H. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. It is miscible with[r]

at equilibrium (i.e., when the reaction has come tocompletion and when neither A or B is being lost norC or D is being formed), the ratio of the concentrationsof the products times each other divided by the concentrations of the reactants times each other is constant.If K is very small, then there a[r]

PROTECT YOUR OWN LIFE ENVIRONMENT
In our life environment plays an important role. But now we see a green environment that is severely threatened by the consciousness of every person. The present situation is that we are not really interested in protecting the environment[r]

Chemistry is a dynamic and rapidly changing field. It is an extraordinarily interesting subject to study and an intriguing one to teach. The diversity of knowledge of the beginning student presents a unique challenge to the student and to the teacher. This text is written primarily for use in course[r]
