the structure of ice is best characterized as:\na an amorphous solid with no long - range order\nb tightly packed molecules with little space in between\nc a hexagonally - shaped, open framework of molecules\nd a crystal lattice of alternating hydrogen and oxygen atoms
Answer
Brief Explanations:
Ice is a crystalline solid. Water molecules in ice form a hexagonal - shaped, open - framework structure due to hydrogen bonding. This structure has more space between molecules compared to liquid water, which is why ice is less dense than water. Option a is incorrect as ice is a crystalline, not amorphous solid. Option b is wrong because ice has an open structure with significant space between molecules. Option d is incorrect as ice is made of water molecules ($H_2O$) not a lattice of alternating hydrogen and oxygen atoms.
Answer:
c. a hexagonally - shaped, open framework of molecules
