Which type of substances have chemical bonds that are not directional and valence electrons that move freely between the atoms?
a) halogens
b) nonmetals
c) metals
d) salts

c) metals

Explanation:

In metallic bonding there are delocalized electrons that are shared by a number of metal cations. The electrons are free to move and are not confined to a single metal cation. These free flowing electrons give metals its specific properties such as ductility, malleability, electrical conductivity and more.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.
