(a)
Interpretation:
Among the given substances, amorphous solid has to be identified.
Concept Introduction:
Amorphous solids lack such defined arrangement of its components instead disordered or random arrangement does exist in them. They are termed as pseudo solids or super cooled liquids. Example: Glass, Wood etc.
(b)
Interpretation:
Among the given substances, ionic solid has to be identified.
Concept Introduction:
In ionic solids, ions of opposite charges are bind together by electrostatic force and are neatly stacked to form a regular and well-defined structure. Example:
(c)
Interpretation:
Among the given substances, molecular solid has to be identified.
Concept Introduction:
Molecular solids are type of crystalline solids in which the molecules are linked by intermolecular forces. The solid structure is maintained by the intermolecular forces rather than bonds. The forces that holds the solids together are much weaker than for the other types of solids.
(d)
Interpretation:
Among the substance, covalent network solid has to be identified.
Concept Introduction:
In Covalent solids the components are atoms bonded by covalent bond repetitively and thus forms huge network form of solid. Network solids are widely formed by group 14 elements and its compounds. Example: Diamond, Amethyst.
(e)
Interpretation:
Among the given substances, metallic solid has to be identified.
Concept Introduction:
Metallic solids generally consist of metal atoms and the metal atoms are linked by metallic bonds. All the metals and their alloys are generally metallic solids.

- Silicon carbide, SiC, is a very hard, high-melting solid. What kind of crystal forces account for these properties?arrow_forwardGive the formula of a solid containing Si that is (a) molecular (b) ionic (c) network covalentarrow_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_forward
- Arrange the following substances in order of increasing strength of crystal forces: CO2, KCl, H2O, N2, CaO.arrow_forwardDescribe, in general, the structures of ionic solids. Compare and contrast the structure of sodium chloride and zinc sulfide. How many tetrahedral holes and octahedral holes are there per closest packed anion? In zinc sulfide, why are only one-half of the tetrahedral holes filled with cations?arrow_forwardA common prank on college campuses is to switch the salt and sugar on dining hall tables, which is usually easy because the substances look so much alike. Yet, despite the similarity in their appearance, these two substances differ greatly in their properties, since one is a molecular solid and the other is an ionic solid. How do the properties differ and why?arrow_forward
