3.0 PROCEDURE: For each reaction, you should write a total molecular reaction, a total ionic reaction and then remove any spectator ions to produce a final net ionic reaction. In order to simplify your task each reaction has its driving force listed. In more advanced General Chemistry courses, you will be expected to find the driving force yourself (based on the rules given above), but for our purposes it is best for you to simply "experience the steps of producing...
