Which of the following is not a chelating ligand?

What is the coordination number of the central metal ion in $[Fe(C_2O_4)_3]^{3-}$?

The anion of acetylacetone $(acac)$ forms $Co(acac)_3$ chelate with $Co^{3+}.$ The rings of the chelate are

$A$ $2 \ L$ solution is prepared by mixing $0.02 \ mol$ of $[Co(NH_3)_5SO_4]Br$ and $0.02 \ mol$ of $[Co(NH_3)_5Br]SO_4$. If $1 \ L$ of this mixture $X$ is treated with $AgNO_3$ to give $Y$,and another $1 \ L$ of mixture $X$ is treated with $BaCl_2$ to give $Z$,find the moles of $Y$ and $Z$.
