Chemical Reactions in Daily Life

In this discussion, you will do a web search to find an example of a chemical reaction which may be encountered in daily life. Describe a little about the chemical changes that occur. If possible, classify the chemical reaction and write out the chemical equation.

For example, baking soda (sodium hydrogen carbonate) is used in baking. When the baking soda heats up, carbon dioxide and water vapor gases are released, leading to the cookie dough or cake batter rising. This is a decomposition reaction, and the chemical equation is:  2 NaHCO3(s) heatrxn Na2CO3(s)  +  H2O(g)  +  CO2(g)
