Answer to Question 1

ANS: B
When water and mercury are mixed together, they will separate into two distinct liquids because of surface tension. Oxygen and hydrogen will combine to form water. Both salt and chlorine will dissolve in water easily.

Answer to Question 2

ANS: C
Surface tension is generated by the cohesive forces of molecules at a gas-liquid interface or at the interface of two immiscible liquids, such as oil and water. Adhesive forces are attractive forces between two different kinds of molecules, and van der Waals forces are physical intermolecular forces that cause molecules to be attracted to each other.
