Question

determine whether each statement is true or false. hydrogen bonding is the cohesive force between water molecules. water molecules at the surface form hydrogen bonds with only the molecules next to and below them. molecules at the surface of water repel molecules below the surface. hydrogen bonds between water molecules cannot be broken. cohesion occurs between the same kinds of molecules.

Explanation:

1. Hydrogen bonding is indeed the cohesive force between water molecules, which is a well - known property in chemistry.
2. Water molecules at the surface form hydrogen bonds with molecules next to and below them as well as some above in the air in some cases, but mainly with adjacent and lower ones.
3. Molecules at the surface of water do not repel molecules below the surface; rather, there are attractive forces like hydrogen bonds.
4. Hydrogen bonds between water molecules are relatively weak and can be broken, for example, when water is heated.
5. Cohesion is the attraction between the same kinds of molecules.

Answer:

1. True
2. True
3. False
4. False
5. True
