Chapter 16: Q39 E (page 704)

How could you tell experimentally if TiO2 is an ionic solid or a network solid?

Short Answer

Expert verified

Tio2 is an ionic solid. This can be checked by determining the conductivity of the compound.

Step by step solution

01

The ionic solid and network solid

The solid formed by combining ions is known as an ionic bond. An ionic solidconductselectricity because of the presence of ions in it.

The solid formed by combining covalent bonds in the continuous network is known as a network solid.Network solids behave as insulators or semiconductors and do not conduct electricity due to the absence of ions.

02

Explanation

The compound Tio2 is a covalent compoundbecause the titanium and oxygen are bonded by a double bond that consists of the covalent and the oxidation stateof the compound is +4. It also conducts electricity. Thus, it is an ionic solid.

When a person has a severe fever, one therapy used to reduce the fever is an “alcohol rub.” Explain how the evaporation of alcohol from a person’s skin removes heat energy from the body.

Describe what is meant by dynamic equilibrium in terms of the vapor pressure of a liquid.

Compare and contrast the phase diagrams of water and carbon dioxide. Why doesn’t CO2have a normal melting pointand a normal boiling point, whereas water does? Theslopes of the solid/liquid lines in the phase diagrams of H2O andCO2 are different. What do the slopes of the solid/liquid lines indicate in terms of the relative densities of the solid and liquid states for each substance? Howdo the melting points of role="math" localid="1663781921156" H2Oand CO2depend on pressure? How do the boiling points of H2OandCO2 depend on pressure? Rationalize why the critical temperature forH2O is greater than that forCO2.

MnO has either the NaCl type structure or the CsCl type structure. The edge length of the MnO unit cell is 4.47×10-8 cm, and the density of MnO is 5.28 g/cm3.

a. Does MnO crystallize in the NaCl type or the CsCl type structure?

b. Assuming that the ionic radius of oxygen is 140. pm, estimate the ionic radius of manganese.

c. Does the calculated cation-to-anion radius ratio for MnO substantiate your answer in part a? Explain.

Carbon diselenide (CSe2) is a liquid at room temperature. The normal boiling point is 125oC and the melting point is -45.5o . Carbon disulfide (CS2) is also a liquid at room temperature, with normal boiling and melting points of 46.5oC and -111.6oC respectively.
