The electron dot formula for PO 4 3 − is to be drawn. The coordinate covalent bond in PO 4 3 − is to be labeled. Concept introduction: The electron dot formula also known as the Lewis structure is the formula that shows the valence electrons which forms the bond between the atoms in a molecule. The electron pairs that are shared by the atoms are known as bonding electrons and the other electrons that are present in order to complete the octet are known as non-bonding electrons.

(a 4 shows scanning electron microscope (SEM) images of extruded actions of packing bed for two capillary columns of different diameters, al 750 (bottom image) and b) 30-μm-i.d. Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³
