Consider the chemical equilibrium of the reaction. nh4oh(aq) mc014-1.jpg nh4+(aq) + ohmc014-2.jpg(aq) what will happen to the chemical equilibrium if nh4cl is added to this solution? the chemical equilibrium will shift to the right. the chemical equilibrium will not shift. the chemical equilibrium will shift to the left. the chemical equilibrium will be lost.

The allotropes of carbon include a variety of structures that include three-dimensional tetrahedral lattices, planes of hexagonal rings, cylindrical tubes of hexagonal rings, and spheres of five- and six-membered rings. similar shapes of network covalent atomic solids are possible with carbon nitride, boron, and pure silicon (e.g., silicene is a graphene-like allotrope of pure silicon). in contrast, silicates exist as either highly ordered or amorphous (more random) three-dimensional lattices. what could explain why there are there no naturally occurring sheets, stacked sheets, cylindrical tubes, or spheres of network covalent atomic solids composed of silicon and oxygen (sio2)? would pure silicate structures make good lubricants or good electrical conductors?
