Question

Metallic element are _____ (conductors or non-conductors), because ________. Nonmetallic elements are generally ____ (conductors or non-conductors). Pure solid ionic compounds are ______ (conductors or non-conductors), because_____, but molten ionic compounds are ______ (conductors or non-conductors), because _______. Pure molecular compounds are generally _____ (conductors or non-conductors). A concentrated aqueous solution of a strong acid such as HCl is a (conductor or non-conductor), because _____. As the concentration of the HCl solution decreases, the conductance ____ (decreases or increases), because _____. Mixtures of metals are _____ (conductors or non-conductors), because ______.

Answer 1

Answer – We know conductors are those has free flow of electrons or the solution in which has mobile ions or particle move from one place to another place. The current or electricity carry the free moving electrons or ions.

Metallic element are conductors, because flow of electrons.

Nonmetallic elements are generally non-conductors.

Pure solid ionic compounds are non-conductors, because there are no mobile ions, but molten ionic compounds are conductors, because mobile ions.

Pure molecular compounds are generally non-conductors

A concentrated aqueous solution of a strong acid such as HCl is a conductor, because mobile ions.

As the concentration of the HCl solution decreases, the conductance decreases, because number mobile ions gets apart from each other and there is distance increase.

Mixtures of metals are conductors, because free or mobile electrons.
