Fill in the Blanks Net Ionic EquationOnline version A Fill in the Blanks game to test your knowledge of net ionic equations and chemical reactions. by Mona Y 1 reactants spectator ions chemical equation chemistry net ionic equation analyze complex reactions chemical reaction products stoichiometry ions A is a that shows only the that are involved in a . It excludes the , which are ions that do not participate in the reaction . The purpose of writing a net ionic equation is to focus on the essential chemical species that are undergoing a change . By eliminating the spectator ions , the net ionic equation provides a clearer representation of the actual chemical reaction . It allows chemists to identify the key and , as well as the of the reaction . Net ionic equations are commonly used in to simplify and the underlying chemistry .
