Answer

See answer below.

Work Step by Step

a) Sodium: $Na^+$, hypochlorite: $ClO^-$ NaClO. It's ionic because there is a metal (Na) bonded to a nonmetal (Cl). b) $BI_3$ Not ionic because it's a metalloid (B) bonded to a nonmetal (I). c) Aluminum: $Al^{3+}$, perchlorate: $ClO_4^-$ $Al(ClO_4)_3$. It's ionic because there is a metal (Al) bonded to nonmetal (Cl). d) Calcium: $Ca^{2+}$, acetate: $H_3C-COO^-$ $Ca(H_3C-COO)_2$. It's ionic because there is a metal (Ca) bonded to a nonmetal (O). e) Potassium: $K^{+}$, permanganate: $MnO_4^{-}$ $KMnO_4$. It's ionic because there are two ions bonded. f) Ammonium: $NH_4^{+}$, sulfite: $SO_3^{2-}$ $(NH_4)_2SO_3$. It's ionic because there are two ions bonded. g) Potassium: $K^{+}$, dihydrogen phosphate: $H_2PO_4^-$ $KH_2PO_4$. It's ionic because there is a metal (K) bonded to nonmetal (P). h) $S_2Cl_2$ Not ionic because it's a nonmetal (S) bonded to a nonmetal (Cl). i) $ClF_3$ Not ionic because it's a nonmetal (Cl) bonded to a nonmetal (F). j) $PF_3$ Not ionic because it's a nonmetal (P) bonded to a nonmetal (F).
