Here's how to break it down:

* Ba: Barium, the chemical symbol for the element.

* (CH₃COO)₂: Acetate ion, which has a charge of -1. Two acetate ions are needed to balance the +2 charge of the barium ion.

* ·2H₂O: Dihydrate, indicating two molecules of water (H₂O) are associated with each formula unit of barium acetate.
