Concept:An exothermic reaction depends on the balance between the energy needed to break bonds and the energy released when new bonds form.
Explanation:Breaking bonds absorbs energy from the surroundings.
Making bonds releases energy back into the surroundings.
For a reaction to be exothermic, the energy released during bond formation must be greater than the energy absorbed during bond breaking.
This gives a net release of energy, so the overall energy change is negative.
Therefore, the correct condition is that the energy given out in making bonds is more than the energy taken in for breaking bonds.
Answer:B. more than energy taken in for breaking bonds
