The number of lone pairs of electrons on the central atom of $\mathrm{BrF}_5, \mathrm{XeO}_3, \mathrm{SO}_2$ respectively are

The shape of colourless neutral gas formed on thermal decomposition of ammonium nitrate is

At $T(\mathrm{~K})$ for one mole of an ideal gas, the graph of $p$ (on $Y$-axis) and $V^{-1}$ (on $X$-axis) gave a straight line with slope of $32.8 \mathrm{~L} \mathrm{~atm} \mathrm{~mol}^{-1}$. What is the temperature (in K$) ?\left(R=0.082 \mathrm{~L} \mathrm{~atm} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}\right)$

At 290 K , a vessel (I) contains equal moles of three liquids $(A, B, C)$. The boiling points of $A, B$ and $C$ are $350 \mathrm{~K}, 373 \mathrm{~K}$ and 308 K respectively. Vessel (I) is heated to 300 K and vapours were collected into vessel (II). Identify the correct statements. (Assume vessel (I) contains liquids and vapours and vessel (II)contains only vapours)

(I) Vessel - I is rich in liquid $B$

(II) Vessel - II is rich in vapour of $C$

(III) The vapour pressures of $A, B, C$ in vessel (I) at 290 K follows the order $C>A>B$
