There are a nuer of indiors you can use to determine whether or not a chemical reaction has occurred. Among them are a change in color, the evolution of a gas, and the production or absorption of heat. To understand why any of these indiors work, we first need to understand what we mean by a chemical reaction, so let’s start there. In
