  Net Ionic Equations

 **__What does a net ionic equation show?__** **A net ionic equation shows the two particles that are occurring in a reaction together. Each particle is written down with mass and charge in mind. A complete ionic equation is an equation that shows dissolved ionic compounds as dissociated free ions. Silver nitrate dissociattes into silver ions and nitrate ions for example. Net ionic equations are equations for reactions in solutions that show only those particles that are directly involved in the chemical change.

A molecular equation is a chemical equation that is a symbolic representation of a chemical reaction. Molecular equation show the replacement of one or more ions in a chemical reaction. Whenever a chemical reaction occurs the two reactants switch places to form a product.

The types of chemical reactions from which these equations can be made are combination, decomposition, single-replacement, double-replacement, and combustion reactions.

Combination reactions occur when two or more substances combine to form a single product.
