Solution of compound a and another 1 m solution of compound b and spots both on a tlc plate and runs the tlc. upon visualizing the plate under uv light, the chemist notices that the spot corresponding to "a" is much darker than the spot corresponding to "b". since identical amounts were applied to the plate, how can the chemist explain the differences in spot intensity?

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
