This reaction is exothermic.
The reaction is endothermic.
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
The reaction reveals the dissociation of solid calcium hydroxide (Ca(OH)₂) into aqueous calcium ions (Ca²⁺) and hydroxide ions (OH⁻). The enthalpy change (ΔH) of -16.71 kJ indicates that the reaction is exothermic, meaning it releases heat to the surroundings. This suggests that when solid calcium hydroxide dissolves in water, it stabilizes into its ionic form, accompanied by a release of energy.
This reaction is exothermic.

The reaction produces heat.
THE REACTION IS ENDOTHERMIC
The reaction shows that calcium hydroxide (Ca(OH)2) dissociates in water to form calcium ions (Ca2+) and hydroxide ions (OH-). This dissociation leads to the formation of two hydroxide ions for every one calcium ion.
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
The reaction produces heat
The reaction shows calcium ions (Ca2+) reacting with hydroxide ions (OH-) to form solid calcium hydroxide (Ca(OH)2) and release heat of 16.71 kJ. This reaction is exothermic, as indicated by the negative enthalpy change.
This is the net ionic equation for the formation of calcium hydroxide, Ca(OH)2 precipitate from soluble calcium ions and soluble hydroxide ions.
The reaction is: Ca + 2H2O = Ca(OH)2 + H2
