The alkene formed as a major product in the elimination reaction of a quaternary ammonium hydroxide (Hofmann elimination) is:[Image showing N-ethyl-N,N-dimethylbutan-1-aminium hydroxide heated]

The “spin-only” magnetic moment [in units of Bohr magneton, (${\mu }_B$)] of ${\text{Ni}}^{2+}$ in aqueous solution would be (Atomic number of $\text{Ni}=28$):

The equilibrium constant for the reaction ${\text{SO}}_3(g)\rightleftharpoons {\text{SO}}_2(g)+\frac{1}{2}{\text{O}}_2(g)$ is $K_c=4.9\times 10^{-2}$. The value of $K_c$ for the reaction $2{\text{SO}}_2(g)+{\text{O}}_2(g)\rightleftharpoons 2{\text{SO}}_3(g)$ will be:

Which of these statements regarding the periodic trends of chemical reactivity of the alkali metals and the halogens is correct?

Given at $25^{\circ }\text{C}$:$\text{AgI}+e^{-}\to \text{Ag}+{\text{I}}^{-},E^{\circ }=-0.152\text{V}$${\text{Ag}}^{+}+e^{-}\to \text{Ag},E^{\circ }=0.800\text{V}$ What is the value of $\log K_{sp}$ for $\text{AgI}$? ($\frac{2.303RT}{F}=0.059\text{V}$)
