Chemical reaction and general college chemistry

Balancing chemical equations Video transcript - Balancing chemical equations is one of those concepts in chemistry that often confuses people. But I think we'll see that if we work through this carefully and methodically, and we also appreciate the art of balancing chemical equations, that it's actually not too bad. So first of all, what is a chemical equation?

CHM General Chemistry I Course - University of Phoenix

Covers the fundamental concepts of acids and bases. Except for some stoichiometry and a discussion on pH, this section is largely qualitative. Acid-base equilibrium calculations are covered in Unit The section on equilibrium calculations contains problem examples illustrating techniques such as iterative and graphical solutions of polynomials, all of which employ the "systematic" method of organizing information.

What's the fundamental difference between a strong acid and a weak acid? Can acid A neutralize base B?

Why are some salts acidic and others alkaline? How do buffers work? What governs the shapes of titration curves? This complete rewrite of the previous pdf document is now organized into seven lessons covering all aspects of the subject.

Considerable effort has been expended to make most of this material accessible to those whose knowledge of thermodynamics is minimal, while still incorporating the proton-free energy concept that makes it easy to answer the questions posed in the preceding paragraph.

Much emphasis is placed on the practical aspects of calculations, including how to deal with quadratic equations and how to judge when approximations are appropriate.

The commonly-taught algebraic method of solving acid-base problems hides the underlying principles and is able to deal with only the simplest systems. The use of log-C vs pH plots avoids the math, provides a bird's-eye view of what's going on in the solution, and yield useful results without algebra.

Finally, there are separate lessons on practical applications physiology, acid rain, and the geochemical carbonate system and, for more advanced students, on exact numerical solutions.The arrow in the equation means "changes to" or "forms." The reaction of gaseous nitrogen with hydrogen to produce ammonia, NH 3, is represented by the chemical equation Although there are thousands of chemical reactions, a significant number of them, especially those that are not organic reactions, can be classified according to four general patterns: combination, decomposition, .

It is important that you know the basic types of chemical reactions for the SAT II Chemistry test since the test often refers to reactions as being of one type or another.
