Complete the equation for the dissociation of Na2CO3 (aq). Omit water from the equation because it is understood to be present.1. Know the difference between molecular and ionic compounds. The first step in writing a net ionic equation is identifying the ionic compounds of the reaction. Ionic compounds are those that will ionize in an aqueous solution and have a charge. [2] Molecular compounds are compounds that never have a charge.
