Physical Techniques used in Inorganic Chemistry

1. How would you determine when the reaction of MgO and Al₂O₃ to produce MgAl₂O₄ was complete?

2. Calculate the wavelength associated with a neutron moving at 2.20 km s^–1. Is this wavelength suitable for diffraction studies? (m_n = 1.675 × 10^–27 kg)

3. Explain why the ¹³C NMR spectrum of Co₂(CO)₉ shows only a single peak at room temperature.

4. Explain the observation that the ¹⁹F NMR spectrum of XeF₅^– consists of a central peak symmetrically flanked by two peaks, each of which is roughly one-sixth of the intensity of the central peak.

5. How would you determine whether the compound Fe₄[Fe(CN)₆]₃ contains discrete Fe(II) and Fe(III) sites?
