AIt is released
BIt is destroyed
CIt is created
DIt is absorbed
Answer & Solution
Correct answer: D. It is absorbed
1. Bonded atoms sit at an energy minimum, so separating them raises the energy of the system.
2. When bonds break, energy is absorbed from the surroundings.
3. When new bonds form, energy is released instead.
4. Every reaction involves both steps, and the balance between them decides the overall energy change.
