Consider the following complex: $[Co(CO_3)(NH_3)_5]ClO_4$.
Mark the correct option for the following parameters in order:
Coordination number $-$ Oxidation number $-$ Number of $d$-electrons $-$ Number of unpaired $d$-electrons.

When $1 \ mol$ of the complex $Co(NH_3)_5Cl_3$ is dissolved in water,it yields $3 \ mol$ of ions. When $1 \ mol$ of the same complex reacts with $2 \ mol$ of $AgNO_3$,it produces $2 \ mol$ of $AgCl_{(s)}$. What is the structure of this complex?
