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

If $1/3$ of the total chlorine in the compound $CrCl_3 \cdot 6H_2O$ is precipitated by adding $AgNO_3$ to its aqueous solution,what is the possible structure of the compound?

Which of the following complexes gives a white precipitate with a solution of barium chloride $(BaCl_2)$?

Which molecule/ion among the following cannot act as a ligand in complex compounds?

$A$ coordination complex compound of cobalt has a molecular formula containing five ammonia molecules,one nitro group,and two chlorine atoms for one cobalt atom. One mole of this compound produces three moles of ions in an aqueous solution,and upon reacting with an excess of $AgNO_3$,it forms $AgCl$ precipitate. The ionic formula for this complex would be:
