Because water molecules are polar and carbon dioxide molecules are nonpolar,
a. water has a lower boiling point than carbon dioxide does.
b. attractions between water molecules are weaker than attractions between carbon dioxide molecules.
c. carbon dioxide cannot exist as a solid.
d. water has a higher boiling point than carbon dioxide does

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
