Chemical reactions and chemical equations

 A chemical reaction is an event.

​A chemical equation is a story about the event.

​

​
Above, we can see evidence of a chemical reaction occurring. The essence of a chemical reaction is that new chemical species are formed.

And below is a chemical equation: chemists' language that gives us some information about the chemical reaction ....

Vive la difference!

Modules in this Chapter 05 explore the difference between chemical changes (reactions) and their representational form (chemical equations), as well as the significance of both.
