Recognizing patterns allows us to predict future behavior. Weather experts use patterns to predict dangerous storms so people can get their families to safety. Political analysts use patterns to predict election outcomes. Similarly, chemists classify chemical equations according to their patterns to help predict products of unknown but similar chemical reactions.

New Fun Fact! There are seven elements who are labeled as "diatomic".  These seven elements can never be alone with only one atom, instead they will always be found in a pair if they are not in a compound. The seven elements are Hydrogen (H2), Nitrogen (N2), Oxygen (O2), Fluorine (F2), Chlorine (Cl2), Bromine (Br2), and Iodine (I2). 

For example, you have seen the synthesis of water as 2H2 + O2 --> 2 H2O. The reason you cannot just say H2 + O --> H2O is because both oxygen and hydrogen are diatomic elements.
