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).
