The reaction of calcium (Ca) typically reveals its tendency to form compounds through oxidation, as it is an alkaline earth metal. When calcium reacts with non-metals, such as oxygen or chlorine, it readily loses two electrons to form Ca²⁺ ions. This characteristic behavior indicates its strong reactivity and its role in forming ionic bonds with other elements. Additionally, it highlights calcium's importance in various biological and industrial processes.
This reaction is exothermic.
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 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.

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 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.
