Answer 2

The balanced Chemical Formula for calcium+water give rise to calcium hydroxide+hydrogen is hereunder:

Calcium hydroxide, commonly known as slaked lime has a wide range of applications. It is formed by the combination of calcium and hydroxide ions.

When a calcium atom gives its two electrons from the outermost orbit and two hydroxide ions take one electron each, both get bonded.

So, Ca (cation) + (OH)² (anion) → CaOH² (chemical formula of Potassium Chloride).

When water is added to the lime, ionization takes place and calcium hydroxide is formed along with the generation of heat.

Hence, the above is possible by the following balanced chemical formula:

Ca + 2H²O → Ca(OH)² + H²↑ (Reactants displaced to form a new product)
