a) Barium fluoride, Silicon tetrachloride, Nickel (II) bromide b) $BaF_2$, $NiBr_2$ are ionic. $SiCl_4$ is molecular. c) 1.0 mol of $NiBr_2$

Work Step by Step

a,b) Ionic: $Ba^{2+}$ - Barium, $F^-$ - Fluoride: Barium fluoride, Molecular: Silicon tetrachloride, Ionic: $Ni^{2+}$ - Nickel(II), $Br^{-}$ Bromide: Nickel (II) bromide c) Molar masses (g/mol): $BaF_2: 175.32,\ SiCl_4:169.90,\ NiBr_2:218.50$. $NiBr_2$ has the largest molar mass and has more amount of moles in the sample, so it's the one with the largest mass.
