Potassium ferrocyanide is a

$A$ $2 \ L$ 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 $Z$.

Identify the tetradentate ligand from the following.

In the brown ring complex $[Fe(H_2O)_5(NO)]SO_4$,nitric oxide behaves as:
