Why do neutralization reactions produce heat?

Answer 1

The response to the query "Why does a neutralization reaction occur?" explains this.

The formation of the strong covalent H-OH bond of the water molecules, from opposite charge #H^+# and #OH^-# ions causes the exothermicity of the reaction and the fact that the amount of evolved energy per mole of water formed is more or less the same independently by the nature of the acid and bases that are neutralized, if these are strong.

Neutralization reactions produce heat because they involve the combination of an acid and a base to form water and a salt. This process releases energy in the form of heat due to the formation of stronger bonds in the resulting water molecule and salt compound compared to the bonds in the original acid and base.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
