$CuSO_{4(aq)}$ $\xrightarrow{H_2S \uparrow} M \downarrow$ $\xrightarrow[\text{Excess}]{KCN} N + O$
Then final products $N$ and $O$ are respectively.

Given below are two statements:
Statement $I$: $PF_5$ and $BrF_5$ both exhibit $sp^3 d$ hybridisation.
Statement $II$: Both $SF_6$ and $[Co(NH_3)_6]^{3+}$ exhibit $sp^3 d^2$ hybridisation.
In the light of the above statements,choose the correct answer from the options given below:

For the reaction $K_4[Fe(CN)_6] \xrightarrow{\text{oxidation}} Fe^{3+} + CO_2 + NO_3^-$,which of the following statements is incorrect?

$A$ mixture $X$ of $0.02 \, mol$ of $[Co(NH_3)_5SO_4]Br$ and $0.02 \, mol$ of $[Co(NH_3)_5Br]SO_4$ was prepared in $2 \, L$ of solution:
$1 \, L$ of mixture $X +$ excess of $AgNO_3 \to Y$
$1 \, L$ of mixture $X +$ excess of $BaCl_2 \to Z$
Number of moles of $Y$ and $Z$ respectively are

The number of ions present in $2 \ L$ of a solution of $1.6 \ M \ K_4[Fe(CN)_6]$ is:
