What is a limitation of using a chemical formula, such as C6H12O6, to represent a compound? A. The chemical formula does not show the types of elements that make up the compound.

B. The chemical formula does not show how the atoms are connected to one another.

C. The chemical formula does not show the number of atoms of each element in a molecule.

D. The chemical formula does not show the chemical symbols of the elements in the compound.

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?
