name	empirical formula
barium chloride

Explanation:

Step1: Determine lead(II) bromide formula

Lead(II) has a charge of +2 ($Pb^{2 + }$) and bromide has a charge of - 1 ($Br^{-}$). To balance the charges, we need 2 bromide ions for 1 lead(II) ion. So the empirical formula is $PbBr_{2}$.

Step2: Determine barium chloride formula

Barium has a charge of +2 ($Ba^{2+}$) and chloride has a charge of -1 ($Cl^{-}$). To balance the charges, we need 2 chloride ions for 1 barium ion. So the empirical formula is $BaCl_{2}$.

Answer:

barium chloride	$BaCl_{2}$
