The relationship between ${\mathrm{K}}_{\mathrm{p}}$ and ${\mathrm{K}}_{\mathrm{c}}$ is ${\mathrm{K}}_{\mathrm{p}}={\mathrm{K}}_{\mathrm{c}}{\left(\mathrm{RT}\right)}^{\mathrm{\Delta n}}$. What would be the value of $\mathrm{\Delta n}$ for the reaction, ${\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{s}\right)\rightleftharpoons {\mathrm{NH}}_3\left(\mathrm{g}\right)+\mathrm{HCl}\left(\mathrm{g}\right)$ ?

For the reaction
$\mathrm{A}\left(\mathrm{g}\right)+\mathrm{B}\left(\mathrm{g}\right)\rightleftharpoons \mathrm{C}\left(\mathrm{g}\right)+\mathrm{D}\left(\mathrm{g}\right);∆\mathrm{H}=-\mathrm{Q} \mathrm{kJ}$
The equilibrium constant cannot be disturbed by

In the reaction $\mathrm{B}(\mathrm{OH}{)}_3+2{\mathrm{H}}_2\mathrm{O}⟶{\left[\mathrm{B}(\mathrm{OH}{)}_4\right]}^{-}+{\mathrm{H}}_3\mathrm{O}$

$\mathrm{B}(\mathrm{OH}{)}_3$ functions as

The conjugate base of ${\mathrm{NH}}_3$ is

Which of the following is the strongest base?

${\mathrm{K}}_{\mathrm{a}}$ values for acids ${\mathrm{H}}_2{\mathrm{SO}}_3,{\mathrm{HNO}}_2,{\mathrm{CH}}_3\mathrm{COOH}$ and $\mathrm{HCN}$ are respectively $1.3\times {10}^{-2},4\times {10}^{-4}, 1.8\times {10}^{-5}$  and $4\times {10}^{-10},$ which of the above acids produces stronger conjugate base in aqueous solution?

Solubility of $\mathrm{AgCl}$ is least in
