I really hope this answer helps you out! :)
Answer:
The correct answer is a. Hydrogen bonding.
Explanation:
The property by which water molecules attract each other is cohesion. groups of water molecules are formed by this interaction by adhesion with other water molecules.
Hydrogen bridges are great forces that hold water molecules together. They form a compact structure that gives it the property of being an almost incompressible liquid. These weak interactions are formed between a hydrogen with a positive partial charge and a more electronegative atom, such as oxygen.
Have a nice day!
Answer:
By repelling water, the tiny water striders stand on the water's surface and the captured airs allows them to float and move easily. so number 2. Surface Tension.
Explanation:
The attraction between water molecules creates tension and a very delicate membrane. Water striders walk on this membrane. ... The legs have tiny hairs that repel water and capture air.
