The role of high-energy X-rays in the fluorescence process has to be explained. Concept introduction: X-ray fluorescence (XRF) is an analysis technique which is based on the principle that when atoms are excited by an energy source, they emit characteristic X-ray photons. X-rays are energetic enough to remove the electrons held tightly in the inner orbitals of the atoms. Fluorescence is a phenomenon which involves the absorption of a radiation of specific energy and re-emission of a radiation usually of lower energy.

Question

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures. Compound C Possible conformations (circle one): Дет

For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically: 1:1 (one mole of EDTA per mole of metal ion) 2:1 (two moles of EDTA per mole of metal ion) 1:2 (one mole of EDTA per two moles of metal ion) None of the above
