Answer: The answer is D, More energy was released in the formation of the 2 HF bonds than in the breaking of the bonds of H2 and F2.

Explanation: Honestly, I guessed on this question and got it right, but I see that right after the arrow on the right side of the equation, there's a 2 in front of the HF(g). On the left side of the equation, it does not match the right side, which led me to believe that there was more energy being released.

The equation tells us that more energy was released in the formation of the 2 HF bonds than in the breaking of the bonds of H2 and F2,therefore option (d) is correct .

What do you mean by the law of conservation of energy?

As per the law of conservation of energy, energy can never be created or destroyed. It can only be converted and transmitted from one form of energy to another.

Energy occurs in various different kinds throughout nature.

The total energy of an isolated system remains constant .

Example for the conservation of energy -:
Conversion of electric energy into sound energy is an example of the conservation of energy.

The equation tells us that more energy was released in the formation of the 2 HF bonds than in the breaking of the bonds of H2 and F2,hence option (d) is correct .
