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 between calcium ions (Ca²⁺) and hydroxide ions (OH⁻) to form solid calcium hydroxide (Ca(OH)₂) indicates a precipitation reaction, where a soluble ionic compound forms an insoluble solid. The enthalpy change (ΔH) of -16.71 kJ suggests that the reaction is exothermic, meaning it releases heat to the surroundings as it proceeds. This indicates a favorable reaction that results in the formation of a stable solid from its aqueous ions.
This reaction is called photosynthesis.
This reaction is called "metal-metal exchange reaction".
An acid plus a base will yield a salt and water in a neutralization reaction.
This is the chemical reaction for burning of propane.
This is the net ionic equation for the formation of calcium hydroxide, Ca(OH)2 precipitate from soluble calcium ions and soluble hydroxide ions.
A Double displacement reaction or Neutralization reaction
this is an exotermic reaction

This indicates a favorable reaction that results in the formation of a stable solid from its aqueous ions.
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 reaction is called hydrolysis.
A and B
A combustion reaction
This reaction is called photosynthesis.
It's a chemical reaction.
No reaction
I suppose that you think to synthesis reaction.
