Introduction

Quantitative relationship among reactants and products are called stoichiometry. Stoichiometry problems are easily solved when amounts of substances are converted from mass (in units of g, kg etc), volume (L), into moles. Amounts in moles depend on how the chemical formula or the chemical reaction equations are written. Chemical reaction equations are the basis for reaction stoichiometry, but when the reactants are not stoichiometric mixtures, some reactants will be in excess whereas others will be in limited supply. The former is called excess reagents whereas the latter are called limiting regents.

Classification is a good method for the organizaiton of information. It is a good start in any study, because it helps to organize our thought and to put information in am order. We can classify chemical reactions according to their common features, and divide chemical reactions into a few types:

On the topic of stoichiometry, we still have to deal with solutions of compounds, electrolytes.

Some Common Features of Chemical Reactions

Classification is a useful scientific method, and we divide chemical reactions into some common types.

Chemical reactions can be beneficial and hazardous. Chemical Reaction Hazards Forum is an Internet site that discusses some recent event related to chemical reactions.

Mechanisms of oscillating reactions, and chain reactions are interesting. These and millions of reactions are still being investigated now.
