H₃O⁺_(aq) + OH-_(aq) → 2H₂O_(l). The heat change accompanying the process represented by the equation above is the heat of

neutralization

formation

solution

dilution

hydration

Answer Details

The heat change accompanying the given process is the heat of neutralization. This is because the reaction involves the combination of hydrogen ions (H+) from an acid (represented by the H3O+ ion) and hydroxide ions (OH-) from a base to form water molecules (H2O). This process of combining an acid and a base to form a salt and water is called neutralization. The heat released or absorbed during this process is known as the heat of neutralization.
