If a shallow pan is filled with water, a drop of red ink is placed in one end of the pan, and a drop of green ink is placed in the other end, which of the following will be true at equilibrium? a. The red ink will be uniformly distributed in one half of the pan, and the green ink will be uniformly distributed in the other half of the pan.
b. The red and green inks will be uniformly distributed throughout the pan.
c. Each ink will move down its concentration gradient.
d. The concentration of each ink will be higher at one end of the pan than at the other end.
e. No predictions can be made without knowing the molecular weights of the pigment molecules.

b. The red and green inks will be uniformly distributed throughout the pan.

Explanation:

The inks distribute throughout the particles of water. It does not matter that one drop of ink was placed in one end, and the other on the other end. The constant movement and collision of particles make the ink's drop distribute uniformly in the pan. Besides, there will we a tendency to have the same amount of ink concentration in all the pan;  to this, they have to distribute evenly.

the answer would be 3

explanation:

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.
