027 - Molecular, Ionic and, Net Ionic Equations
In this video Paul Andersen shows you how to write balanced equations that describe chemical changes. He then gives you a short introduction to balancing equations and uses the PHET site to practice this skill. In aqueous solutions an ionic equation (or complete ionic equation) is helpful in following the ions. When the spectator ions are removed a net ionic equation can be used to show the chemicals that are actually combining in the reaction.
