a) $PtCl_2$, $PtCl_4$ b) $PtS$, $PtS_2$
The ions chloride $Cl^-$ and sulfide $S^{2-}$ would form the following compounds: a) $Pt^{2+}$: balancing the charges: 1 $Pt^{2+}$ and 2 $Cl^-$: $PtCl_2$ $\qquad\qquad\qquad\qquad\qquad\quad\quad\ \$ 1 $Pt^{2+}$ and 1 $S^{2-}$: $PtS$ b) a) $Pt^{4+}$: balancing the charges: 1 $Pt^{4+}$ and 4 $Cl^-$: $PtCl_4$ $\qquad\qquad\qquad\qquad\qquad\quad\quad\ \ \ \ \ \$1 $Pt^{4+}$ and 2 $S^{2-}$: $PtS_2$
