(a)
Interpretation:
A solid that can dissolve in water and melts below 100° C 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.
(b)
Interpretation:
A solid which conducts electricity only when melted 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 electrostatic forces between cations and anions.
(c)
Interpretation:
A solid that is insoluble in water and conducts electricity needs to be classified as metallic, network covalent, ionic or molecular.
Concept introduction:
Metals, in which the structural units are electrons and cations, which may have charges of +1, +2 or +3.

- 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_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_forwardThe normal boiling point of SO2 is 263.1 K and that of NH3 is 239.7 K. At −40 °C, would you predict that ammonia has a vapor pressure greater than, less than, or equal to that of sulfur dioxide? Explain.arrow_forward
