Answer the following question given this paragraph: A: The energy is stored in the bonds of the products as chemical energy. In an endothermic reaction, the products have more stored chemical energy than the reactants. This is represented by the graph on the left in the Figure below . In an exothermic reaction, the opposite is true. The products have less stored chemical energy than the reactants. You can see this in the graph on the right in the Figure below . Q: Endothermic and exothermic reactions differ in whether the products or reactants store more of what? Choices: - Motion energy - Thermal energy - Kinetic Energy - chemical energy A:
chemical energy

Answer the following question given this paragraph: In a transverse wave, particles of the medium move up and down at right angles to the direction of the wave. Wave amplitude of a transverse wave is the difference in height between the crest and the resting position. The crest is the highest point particles of the medium reach. The higher the crests are, the greater the amplitude of the wave. Q: In a transverse wave, the highest point the wave reaches is known as the? Choices: - flow - valley - axis - crest A:
crest
