Step by step solution

01

a. Diamond

Diamond is a covalent solid, as it consists of carbon atoms covalently bonded together in a tetrahedral arrangement.
02

b. PH3

PH3 (phosphine) is a molecular solid, as it is formed by discrete molecules of phosphorous and hydrogen that are held together by weak van der Waals forces.
03

c. H2

H2 (hydrogen) is a molecular solid, as it consists of discrete H2 molecules held together by weak van der Waals forces.
04

d. Mg

Mg (magnesium) is a metallic solid, as it consists of a regular arrangement of magnesium atoms, where the electrons are delocalized and form a "sea of electrons" that holds the metal lattice together.
05

e. KCl

KCl (potassium chloride) is an ionic solid, as it consists of potassium (K+) and chloride (Cl-) ions held together by electrostatic ionic bonds.
06

f. Quartz

Quartz is a covalent solid, as it consists of silicon and oxygen atoms covalently bonded together in a tetrahedral network.
07

g. NH4NO3

NH4NO3 (ammonium nitrate) is an ionic solid, as it consists of ammonium (NH4+) and nitrate (NO3-) ions held together by electrostatic ionic bonds.
08

h. SF2

SF2 (sulfur difluoride) is a molecular solid, as it consists of discrete SF2 molecules held together by weak van der Waals forces.
09

i. Ar

Ar (argon) forms a molecular solid, as it consists of discrete argon atoms held together by weak van der Waals forces, also known as an "argon lattice" when in solid form.
10

j. Cu

Cu (copper) is a metallic solid, as it consists of a regular arrangement of copper atoms, with the electrons being delocalized forming a "sea of electrons" that holds the metal lattice together.
11

k. C6H12O6

C6H12O6 (glucose) is a molecular solid, as it consists of discrete glucose molecules held together by weak van der Waals forces.

Aluminum has an atomic radius of 143 \(\mathrm{pm}\) and forms a solid with a cubic closest packed structure. Calculate the density of solid aluminum in \(\mathrm{g} / \mathrm{cm}^{3}\) .

A plot of \(\ln \left(P_{\text { vap }}\right)\) versus 1\(/ T(\mathrm{K})\) is linear with a negative slope. Why is this the case?

X rays of wavelength 2.63 A were used to analyze a crystal.The angle of first- order diffraction \((n=1 \text { in the Bragg }\) equation) was 15.55 degrees. What is the spacing between crystal planes, and what would be the angle for second-order diffraction \((n=2) ?\)

The CsCl structure is a simple cubic array of chloride ions with a cesium ion at the center of each cubic array (see Exercise 71 ). Given that the density of cesium chloride is 3.97 \(\mathrm{g} /\) \(\mathrm{cm}^{3},\) and assuming that the chloride and cesium ions touch along the body diagonal of the cubic unit cell, calculate the distance between the centers of adjacent \(\mathrm{Cs}^{+}\) and \(\mathrm{Cl}^{-}\) ions in the solid. Compare this value with the expected distance based on the sizes of the ions. The ionic radius of \(\mathrm{Cs}^{+}\) is \(169 \mathrm{pm},\) and the ionic radius of \(\mathrm{Cl}^{-}\) is 181 \(\mathrm{pm} .\)

Packaged foods that require cooking in boiling water often contain special directions for use at high elevations. Typically these directions indicate that the food should be cooked longer above 5000 ft. Explain why it takes longer to cook something at higher elevations.
