Fill in the blank: Energy is ______ causing broken bonds.

Explanation:
The main idea here is that breaking bonds requires energy input. To rupture chemical bonds, energy must be supplied to the system to overcome the bond's strength, which is why bond breaking is endothermic. Saying energy is introduced emphasizes that energy is added from the surroundings to the molecules, starting the process of bond breakage. If energy were released, it would imply the opposite process (bond formation or an exothermic step), and generation would suggest creating energy rather than providing it. So introducing energy to the system aligns with the concept that bonds break when energy is put in.
