Concept explainers
(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.
(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.
(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.

(c) are generally soluble in nonpolar solvents?arrow_forwardOn the basis of the description given, classify each of the following solids as molecular, metallic, ionic, or covalent network. Explain your answers. a a lustrous, yellow solid that conducts electricity b a hard, black solid melting at 2350C to give a nonconducting liquid c a nonconducting, pink solid melting at 650C to give an electrically conducting liquid d red crystals having a characteristic odor and melting at 171Carrow_forwardDefine critical temperature and critical pressure. In terms of the kinetic molecular theory, why is it impossible for a substance to exist as a liquid above its critical temperature?arrow_forward
- Of the four general types of solids, which one(s) (a) are generally insoluble in water? (b) have very high melting points? (c) conduct electricity as solids?arrow_forwardExplain why liquids assume the shape of any container into which they are poured, whereas solids are rigid and retain their shape.arrow_forwardIn terms of their bulk properties, how do liquids and solids differ?
