12. Energy from the breaking of atomic bonds in molecules (ex: C4 explosion) need help[ its physical science

endothermic energy or chemical energy

Explanation:

An endothermic process increases the enthalpy H of the system, during which the closed system (usually) absorbs thermal energy from its surroundings.

Chemical energy is the form of potential energy in which energy is stored in chemical bonds. The breaking of chemical bonds absorbs energy, while the formation of new bonds releases energy.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
