It offers guidelines for writing and balancing equations, emphasizing the importance of correct formulas, atom counting, and using the lowest coefficient ratios. An example of balancing the reaction between lead(II) nitrate and sodium chloride is provided to illustrate the process.

It also discusses combination reactions, where multiple substances unite to form new ones, such as elements reacting with oxygen to create oxides. The text provides examples of balancing equations for these reactions, including potassium oxide formation and the reaction of calcium oxide with water.

Chemical reactions can occur rapidly, like the explosive reaction of sodium metal in the presence of water, and others occur very slowly, like the rusting of iron or the tarnish that slowly develops on some metal surfaces exposed to air.

Cars and other vehicles burn gasoline in order to power their engines. Batteries use electrochemical reactions to produce energy and power many everyday devices. Many chemical reactions are going on inside you as well, especially during the digestion of food.
