Chapter 2.3, Problem 2CP
Interpretation Introduction

Interpretation:

The mass number of an oxygen atom having nine neutrons in its nucleusis to be determined

Concept introduction:

The atomic number (Z) is the number of protons in the nucleus of each atom of an element. It also indicates the number of electrons in an atom. Mathematically, it can be represented as follows:

Atomic number(Z)= No. of electrons or protons

Mass number (A) is the total number of protons and neutrons present in the nucleus of an atom of an element. Mathematically, it can be represented as follows:

Mass number(A)= No. of protons (Z) + No. of neutrons

The atomic number and mass number of the element with symbol X are represented as follows:

ZAX

Here, A is the mass number (number of protons + number of neutrons), Z is the atomic number (number of protons), and X is the element’s symbol.

(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

What impact (increase, decrease, or no change) does each of the following conditions have on the individual components of the van Deemter equation and consequently, band broadening? Increase temperature Longer column Using a gas mobile phase instead of liquid Smaller particle stationary phase Multiple Paths Diffusion Mass Transfer
34. Figure 3 shows Van Deemter plots for a solute molecule using different column inner diameters (i.d.). A) Predict whether decreasing the column inner diameters increase or decrease bandwidth. B) Predict which van Deemter equation coefficient (A, B, or C) has the greatest effect on increasing or decreasing bandwidth as a function of i.d. and justify your answer. Figure 3 Van Deemter plots for hydroquinone using different column inner diameters (i.d. in μm).
