Every chemical reaction begins with the formula of one or more substances (reactants) followed by an arrow and ends with the formula of one or more substances (products). There are many types of chemical reactions; however, only a few basic types appear in this chapter. Redox reactions tend to be more difficult to balance than the other reactions here, so you use a systematic approach to balance most redox reactions.
The Problems You’ll Work On
In this chapter, you work with chemical reactions in the following ways:
Identifying types of reactions
Balancing chemical equations
Balancing redox reactions
Note: See the Appendix if you need to check the periodic table.
What to Watch Out For
Remember the following when working on chemical reactions:
When balancing equations, never change a chemical formula; change only the coefficients.
There are only a few basic reaction types here, so don’t invent new ones. But note that a reaction may fit into more than one ...
