Question

the structure of ice is best characterized as: a a crystal lattice of alternating hydrogen and oxygen atoms b an amorphous solid with no long - range order c a hexagonally - shaped, open framework of molecules d tightly packed molecules with little space in between

Explanation:

Ice is a crystalline solid. Water molecules in ice form a hexagonal - shaped, open - framework structure due to hydrogen bonding. It is not a lattice of alternating hydrogen and oxygen atoms (water molecules are H₂O), not an amorphous solid, and not tightly - packed as its structure has open spaces.

Answer:

C. a hexagonally - shaped, open framework of molecules
