Approximately 1 ml of two clear, colorless solutions-0.1 m ba(no3)2and 0.1 m na2so4- were combined. upon mixing, a thick, milky white precipitate formed. after centrifugation, the solution above the precipitate was found to be clear and colorless. based on these observations, determine if a reaction occurred. if so, write the balanced chemical equation and net ionic equation for the reaction.

2. predict if a reaction would occur when solutions of 0.1 m al(no3)2and 0.1 m ki are combined. explain your reasoning, and, if you predict a reaction will occur, include the net ionic equation for the reaction.

3. when a solution of 0.1 m mg(no3)2was mixed with a limited amount of aqueous ammonia, a light white, wispy solid was observed, indicating a reaction took place. write the net ionic equation for this reaction.
