Hydrochloric acid and sodium hydroxide react to produce water and sodium chloride in an endothermic reaction. Which statement must be true of the reaction?(1 point)

Responses

The energy of each bond in water and sodium chloride is greater than the energy of each bond in hydrochloric acid and sodium hydroxide.
The energy of each bond in water and sodium chloride is greater than the energy of each bond in hydrochloric acid and sodium hydroxide.

More bond energy is absorbed on the reactants side than is released on the products side.
More bond energy is absorbed on the reactants side than is released on the products side.

The bond energy used to break the bonds in hydrochloric acid and sodium hydroxide is less than the energy released to form the bonds in water and sodium chloride.
The bond energy used to break the bonds in hydrochloric acid and sodium hydroxide is less than the energy released to form the bonds in water and sodium chloride.

The total bond energy of water and sodium chloride is greater than the total bond energy of hydrochloric acid and sodium hydroxide.

In order to understand the nature of an endothermic reaction, let's focus on what an endothermic reaction signifies. In an endothermic reaction, energy is absorbed from the surroundings, which means that the energy required to break the bonds in the reactants is greater than the energy released during the formation of the products.

For the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) to produce water (H₂O) and sodium chloride (NaCl), the correct statement based on the endothermic nature of the reaction would be:

More bond energy is absorbed on the reactants side than is released on the products side.

This statement directly reflects the endothermic nature of the reaction involved. The other statements do not accurately describe the relationship between the bond energies in an endothermic process.
