Final answer:

The precipitate for NaOH BaCl2 is Ba(OH)2 (option B). A double displacement reaction occurs, resulting in the formation of barium hydroxide (Ba(OH)2) and sodium chloride (NaCl). Ba(OH)2 is a white precipitate that indicates a chemical change has occurred.

Step-by-step explanation:

The precipitate for NaOH BaCl2 is Ba(OH)2 (option B). When sodium hydroxide (NaOH) is added to barium chloride (BaCl2), a double displacement reaction occurs resulting in the formation of barium hydroxide (Ba(OH)2) and sodium chloride (NaCl). Ba(OH)2 is a white precipitate that indicates a chemical change has taken place.
