Answer

Brief Explanations:

In chemical formulas, when indicating multiple polyatomic ions, parentheses are placed around the atoms in the ion and then a subscript is added to show the number of such polyatomic ions. For example, in calcium hydroxide $Ca(OH)_2$, the $(OH)$ is the polyatomic ion hydroxide and the subscript 2 indicates two hydroxide ions.

Answer:

B. Put parentheses around the atoms in the ion and then add a subscript.
