For the following questions answer them individually
The compound that does NOT liberate $$CO_2$$, on treatment with aqueous sodium bicarbonate solution, is
Concentrated nitric acid, upon long standing, turns yellow-brown due to the formation of
Methylene blue, from its aqueous solution, is adsorbed on activated charcoal at $$25^\circ C$$. For this process, the correct statement is
The arrangement of $$X^-$$ ions around $$A^+$$ ion in solid AX is given in the figure (not drawn to scale). If the radius of $$X^-$$ is 250 pm, the radius of $$A^+$$ is
Upon treatment with ammoniacal $$H_2S$$, the metal ion that precipitates as a sulfide is
The standard enthalpies of formation of $$CO_2(g), H_2O(l)$$ and glucose(s) at $$25^\circ C$$ are -400 kJ/mol, -300 kJ/mol and -1300 kJ/mol, respectively. The standard enthalpy of combustion per gram of glucoseat $$25^\circ C$$ is
Consider the following complex ions, P, Q and R.
$$P = [FeF_6]^{3-}, Q = [V(H_2O)_6]^{2+}$$ and $$R = [Fe(H_2O)_6]^{2+}$$
The correct order of the complex ions, according to their spin-only magnetic moment values (in B.M.) is
In the reaction,
$$P + Q \rightarrow R + S$$
the time taken for 75% reaction of P is twice the time taken for 50% reaction of P. The concentration of Q varies with reaction time as shown in the figure. The overall order of the reaction is
KJ in acetone, undergoes $$S_N2$$ reaction with each of P, Q, R and S. The rates of the reaction vary as
