Chapter 9, Problem 39QAP

Interpretation Introduction

(a)

Interpretation:

A solid that is insoluble in water, melts above 500° C and does not conduct electricity needs to be classified as metallic, network covalent, ionic or molecular.

Concept introduction:

Solids in which atoms are joined by a continuous network of covalent bonds are called network covalent solids.

Interpretation Introduction

(b)

Interpretation:

A solid that can dissolve in water but does not conduct electricity as an aqueous solution, as a solid or when molten needs to be classified as metallic, network covalent, ionic or molecular.

Concept introduction:

Solids in which constituent particles are covalent molecules which are held together by weak intermolecular forces are called molecular solids.

Interpretation Introduction

(c)

Interpretation:

A solid that can dissolve in water, melts above 100(C and conducts electricity as an aqueous solution needs to be classified as metallic, network covalent, ionic or molecular.

Concept introduction:

Ionic solids consist of cations and anions. They are held together by strong electrical forces between negative charged ions adjacent to one another.
