Back 9

A polyatomic ion, also known as a molecular ion, is a charged chemical species composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit.

double replacement reason

Back 13

Chemical reactions can be divided into several classes each having similar characteristics. These different types of reactions will be discussed in greater detail throughout the book. You will find that almost every reaction you see can fall into one of these categories, so make sure that you understand them.
