If a solution process is exothermic, how does the energy required for dissolving the solute compare with the energy released?
the energy required is more than the energy released.
the energy required is equal to the energy released.
the energy required is less than the energy released.

How have the competing explanations' experiments on atoms affected the development of the atomic model?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
