Which of the following oxides of group 16 has the highest boiling point?
\(0.20 \mathrm{~g}\) of an organic compound gave \(0.12 \mathrm{~g}\) of \(\mathrm{AgBr}\). By using Carius method, the percentage of bromine in the compound will be
\(\mathrm{MnO}_4^{-}\) is good oxidising agent in different medium changing to
$$\mathrm{MnO}_4^{-} \rightarrow \mathrm{Mn}^{2+} \rightarrow \mathrm{MnO}_4^{2-} \rightarrow \mathrm{MnO}_2 \rightarrow \mathrm{Mn}_2 \mathrm{O}_3$$
Change in oxidation number respectively are :
Which of the following has maximum dipole moment?
Calculate the wavelength associated with an electron moving with a velocity of \(10^6 \mathrm{~m} / \mathrm{s}\) (mass of electron \(=9.1 \times 10^{-31} \mathrm{~kg}, h=6.6 \times 10^{-34} \mathrm{~kg} \mathrm{~m}^2 \mathrm{~s}^{-1}\) )
If \(\mathrm{AgI}\) crystallises in zinc blende structure with \(\mathrm{I}^{-}\) ions at lattice points then the fraction of tetrahedral voids occupied by \(\mathrm{Ag}^{+}\) ions is
