Question
When a chlorine-chlorine bond is formed, 58 kcal of energy is ______. To break the same bond, 58 kcal of energy is ______.Multiple choice question.absorbed; absorbedreleased; absorbedreleased; releasedabsorbed; released
Solution
When a chlorine-chlorine bond is formed, 58 kcal of energy is released. This is because energy is released when bonds are formed. On the other hand, to break the same bond, 58 kcal of energy is absorbed. This is because energy is required to break bonds. So, the correct answer is "released; absorbed".
