Activity Overview

In this investigation we will explore the nature of a reaction from the POV of the ingredients. When chemicals mix to form compounds they don't always match in such a way that all ingredients are used. In some cases you use all of one element and leave some of the other, or in some cases you have a little of each left because you don't have enough left to combine to make another molecule of the compound. This part of chemistry is called Stoikiometry and includes some mathematics.

Before the Activity

Students should have balanced equations and written chemical formulas.

During the Activity
