When $AgNO_3$ is heated strongly,the products formed are

Two oxides of nitrogen, $NO$ and $NO_2$, react together at $253 \ K$ to form a compound of nitrogen $X$. $X$ reacts with water to yield another compound of nitrogen $Y$. The shape of the anion of $Y$ is:

In the following reaction,identify the nature of the product formed by the complete hydrolysis of the underlined atom at $R.T.$:
$\underline{N}F_3 + H_2O \longrightarrow \text{No reaction}$

The product formed in the reaction of $SOCl_2$ with white phosphorus is:

Assertion $:$ Reducing nature of pnicogen hydrides increases on moving down the group.
Reason $:$ Thermal stability of pnicogen hydrides decreases on moving down the group.
