Chemical Principles
Chemistry, it is a word that evokes various, and often dramatic, responses. It is a word that is impossible to define concisely, because the field is so diverse, and its practitioners perform such an incredible variety of jobs. Chemistry mainly deals with situations in which the nature of a substance is changed by altering its composition; entirely new substances are synthesized or the properties of existing substances are enhanced. The goal of this chapter is to introduce some of the important aspects of chemistry not typically discussed in connection with learning chemistry.
