The energy diagram shows the changes in energy during a chemical reaction. Which statement best describes the total energy change of the system?
Potential energy
n
Reaction progress
O A. The reactants have higher potential energy, and energy is
released.
OB. The reactants have lower potential energy, and energy is
absorbed.
O C. The reactants have lower potential energy, and energy is released.
O D. The reactants have higher potential energy, and energy is
absorbed

D

Explanation:

reactants have higher potential energy and energy is absorbed

need to see circuit to get time constant

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
