Which of the following statements accurately describe ice:
I. Ice is denser than water. II. Hydrogen bonds hold ice molecules closer together than they do liquid water molecules. III. Ice has a crystalline structure.
A - II
B - I, II, and III
C - I
D - II and III
E - III
Answer: E - III Ice has a crystalline structure.
The hydrogen bonds in ice are different than in liquid. As a liquid hydrogen bonds are constantly being formed and breaking apart but in ice all the hydrogen bonds that are going to be made are. They are becoming more ordered and rigid, in a crystalline structure. This structure is holding them farther apart.
