Prelab: Chemical Reactions Name three types of double displacement reactions. How are they defined? What pushes the double displacement reactions toward completion? Consider the reaction of aqueous hydrochloric acid and aqueous barium hydroxide. Write balanced molecular, complete ionic, and net ionic equations for this chemical reaction. What are spectator ions? Identify any spectator ions from the reaction in the question above. How can one predict whether two aqueous solutions will/will not undergo a double displacement reaction? A single displacement reaction...
