Question

question 4 of 10 which describes two phases in dynamic equilibrium? a. molecules in one phase continually change to the other. b. molecules do not change from one phase to the other. c. the total number of molecules must be equal in each phase. d. the total number of molecules in each phase stays constant.

Explanation:

In dynamic equilibrium between two phases, there is a continuous exchange of molecules between the phases, but the net amount of molecules in each phase remains constant. It's not about equal number of molecules in each phase, and molecules do change from one phase to another.

Answer:

D. The total number of molecules in each phase stays constant.
