Question

question 45 water molecules have a slight bond between themselves and other water molecules and is responsible for surface tension. these bonds are called a. van der waals forces b. hydrogen c. covalent d. ionic e. magnetism

Explanation:

Hydrogen bonds between water - molecules cause surface - tension. Van der Waals forces are weaker and not the main cause here. Covalent bonds are within the water molecule, not between them for surface - tension. Ionic bonds are not relevant for water - water interactions causing surface - tension, and magnetism is unrelated.

Answer:

B. hydrogen
