The correct explanation for why the burning of methane (the process represented by the equation \( CH_4 + 2O_2 \rightarrow 2H_2O + CO_2 \)) is exothermic is:
**D. Less energy is absorbed from the breaking of old bonds than is released from the formation of new bonds.**
In exothermic reactions, the energy released when new bonds are formed in the products is greater than the energy required to break the bonds in the reactants, resulting in a net release of energy.
**D. Less energy is absorbed from the breaking of old bonds than is released from the formation of new bonds.**
In exothermic reactions, the energy released when new bonds are formed in the products is greater than the energy required to break the bonds in the reactants, resulting in a net release of energy.
