Why does every chemical reaction require a certain amount of activation energy? Ο Α.
Energy is released when the reactants begin to react.
OB
Energy lost to the environment during the reaction must be replaced.
O c.
Forming the activated complex requires energy.
OD
The products have more potential energy than the activated complex.
OE.
The reactants have less potential energy than the products.

Two people each hold the end of a rope and create waves by moving their arms up and down. this wave is best classified as a transverse wave because a) both the rope particles and the wave are moving in the same direction. b) the wave is moving up and down as the particles of the rope move horizontally. c) the wave is moving horizontally as the particles of the rope move up and down. eliminate d) the wave is moving in a parallel direction with the motion of the person's arms.
