Question

Given the balanced equation representing a reaction:
2NaCl → 2Na + Cl2
To break the bonds in NaCl, the reactant must
(1) absorb energy (3) destroy energy
(2) create energy (4) release energy

Answer 1

2 and 3 are not possible because energy cannot be created nor destroyed. In order to break bonds, energy must be absorbed, so 1 is your answer!

Answer 2

1 is the answer i think.
