On adding water to $BiCl_3$ solution in $HCl$,the compound produced is

$Assertion :$ Nitrogen and oxygen are the main components in the atmosphere but these do not react to form oxides of nitrogen.
$Reason :$ The reaction between nitrogen and oxygen requires high temperature.

Why does $PCl_3$ fume in moisture?

Match List $I$ with List $II$:

List $I$ Oxide	List $II$ Type of Bond
$A. N_2O_4$	$I. 1 N-O$ bond
$B. NO_2$	$II. 1 N-O-N$ bond
$C. N_2O_5$	$III. 1 N-N$ bond
$D. N_2O$	$IV. 1 N=N / N\equiv N$ bond

Choose the correct answer from the options given below:

Which of the following elements forms a new compound when exposed to air?

The $15^{th}$ group of the periodic table contains elements $N, P, As, Sb,$ and $Bi$. As we move from $N$ to $Bi$,how do the oxides with the general formula $E_2O_3$ behave?
