Ca(s) + 2H₂O(l) → Ca(OH)₂(aq) + H₂(g)
Here's what happens:
* Calcium (Ca) is more reactive than hydrogen (H), so it displaces hydrogen from water.
* Calcium hydroxide (Ca(OH)₂) is formed as a product, which is soluble in water and exists as an aqueous solution.
* Hydrogen gas (H₂) is released as a byproduct.
Important Note: This reaction is exothermic, meaning it releases heat. The reaction can be vigorous, and the hydrogen gas produced is flammable. Therefore, this reaction should be conducted with caution in a well-ventilated area.
