which statement explains the relationship between the amount of energy it takes to break a bond and amount of energy released when the same bond is formed?
A ) the amounts of energy are always equal.
B ) the amount of energy it takes to break a bond is always greater than the amount of energy released when the bond is formed.
C ) the relationship depends on the particular bond.
D ) the amount of energy it takes to break a bond is always less than the amount of energy released when the bond is formed.
A) The amounts of energy are always equal.
This is known as the conservation of energy, which is a fundamental concept in chemistry and physics. The energy required to break a bond (bond dissociation energy) is exactly equal to the energy released when that same bond is formed (bond formation energy), assuming that all conditions are the same and that the reaction occurs in a closed system with no energy loss to the surroundings.
When a bond is broken, energy is absorbed from the surroundings to overcome the attraction between the atoms. Conversely, when a bond is formed, that same amount of energy is released, as the atoms come together to lower their potential energy, achieving a more stable state.
