Chemical Reactions

4.2  Net Ionic Equations

Essential Knowledge:

*These are taken directly from College Board

• All physical and chemical processes can be represented symbolically by balanced equations. (TRA-1.B.1 )  

• Chemical equations represent chemical changes. These changes are the result of a rearrangement of atoms into new combinations; thus, any representation of a chemical change must contain equal numbers of atoms of every element before and after the change occurred.Equations thus demonstrate that mass is conserved in chemical reactions (TRA-1.B.2 )  

• Balanced molecular, complete ionic, and net ionic equations are differing symbolic forms used to represent a chemical reaction. The form used to represent the reaction depends on the context in which it is to be used. (TRA-1.B.3)
