$0.5 \mathrm{g}$ of an organic compound cantaining $\mathrm{N}$ on Kjeldahlising required $29 \mathrm{ml}$ of $\mathrm{N}/5{\mathrm{H}}_2{\mathrm{SO}}_4$ for complete neutralization of ${\mathrm{NH}}_3$. The percentage of $\mathrm{N}$ in the compound is

$0.4 \mathrm{g}$ of organic compound gave $0.188 \mathrm{g}$ of $\mathrm{AgBr}$. The percentage of $\mathrm{Br}$ in the compound is

$\mathrm{F}$ cannot be tested by "Lassaigne's test" because

$0.20 \mathrm{g}$ of organic compound gave $0.5544 \mathrm{g}$ of ${\mathrm{BaSO}}_4$ The percentage of $\mathrm{S}$ is

$0.64 \mathrm{g}$ of organic compound give $1.2535 \mathrm{g}$ of ${\mathrm{Mg}}_2{\mathrm{P}}_2{\mathrm{O}}_7$. The percentage of $\mathrm{P}$ is

Which of the following will not give the Lassaigne test for nitrogen?

In detection of 'P' by fusing with ${\mathrm{Na}}_2{\mathrm{O}}_2$ and then extracting it with water, we add ${\mathrm{HNO}}_3$ (conc.) and ammonium molybdate to get

Which is not correct match?
