Describe the differences between goethite, hematite and ferrihydrite and explain which of these Fe oxides is most likely to form in tropical soils.
Use symmetry analysis to generate a molecular orbital diagram for XeF4. As a basis set, consider one σ-bonding hybrid on each F that can be treated the same way as a hydrogen 1s orbital. Ignore the lone pairs/ p orbitals on Flourine.
