What causes the release of energy in an exothermic reaction? Bonds breaking Bonds breaking A catalyst A catalyst Bonds being formed Bonds being formed Electrons escaping the bond

weak bonds break and strong bonds form

Explanation:

An exothermic reaction is a chemical reaction in which heat energy is evolved during the reaction process.

Bond formation requires energy while bond breakage releases energy. More energy is needed for the formation of weak bonds as compared to strong bonds.

Hence, when weak bonds break, they release more energy than needed to make a corresponding strong bond leading to the release of the remaining energy as heat.

the answer is na (sodium)

i think its 100

i hope this !
