Predict the correct intermediate and product in the following reaction:

If molality of the dilute solution is doubled, the value of molal depression constant ($K_f$) will be:

The heating of phenyl-methyl ethers with $\text{HI}$ produces:

In the electrochemical cell $\text{Zn}\mid {\text{ZnSO}}_4(0.01\text{M})\parallel {\text{CuSO}}_4(1.0\text{M})\mid \text{Cu}$, the emf is $E_1$. When the concentrations are swapped (${\text{ZnSO}}_4=1.0\text{M}$, ${\text{CuSO}}_4=0.01\text{M}$), the emf is $E_2$. The relationship is:

A first order reaction has a specific reaction rate of $10^{-2}{\text{s}}^{-1}$. How much time will it take for $20\text{g}$ of the reactant to reduce to $5\text{g}$?
