3.1 Chemical Equations

In the first two chapters we laid the foundation for what is to come in Chapter 3. We built this foundation based on observations in the laboratory and discussed how to interpret, calculate, and manipulated measured quantities. We also analyzed atoms, molecules, and compounds and discussed their properties.

Now it’s time to start observing what happens when we react chemical species together. How do we represent chemical reactions on paper? When two or more reactants are combined together, how can we determine the quantity of products produced? How can we use Stoichiometry to examine the quantity of substances produced and consumed in chemical reactions? This Chapter will answer these questions and then some as we begin to analyze chemical formulas and equations.

Chemical Reactions are represented by chemical equations. These equations list all the reactants and products in a chemical reaction.

3.1 Chemical Reactions

Once the reactants and products are determined for a chemical reaction, those products must be balanced in order to properly determine the amount of a reactant(s) consumed or the amount of the product(s) produced.
