If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
Ca + 2 HCl = CaCl2 + H2
the reaction produces heat

THE REACTION IS ENDOTHERMIC
A white precipitate, that appears to be milky. Ca^2+(aq) + 2OH^-(aq) = Ca(OH)2 (s)
The reaction produces heat
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 is: Ca + 2H2O = Ca(OH)2 + H2
This is the net ionic equation for the formation of calcium hydroxide, Ca(OH)2 precipitate from soluble calcium ions and soluble hydroxide ions.
