Calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable (unlike its sister magnesium) but not fast enough at room temperature to generate much heat. Part of the slowness of the calcium-water reaction results from the metal being partly protected by insoluble white calcium hydroxide.

calcium | Definition, Properties, & Compounds | Britannica
The metal reacts slowly with oxygen, water vapour, and nitrogen of the air to form a yellow coating of the oxide, hydroxide, and nitride. It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water (and more slowly with cold water) to produce hydrogen gas and calcium hydroxide.
Water-reactive substances - Wikipedia
However, if a metal reacts with steam, like magnesium, metal oxide is produced as a result of metal hydroxides splitting upon heating.  The hydroxides of calcium, strontium and barium are only slightly water-soluble but produce sufficient hydroxide ions to make the environment basic , …
Carbonatation - Wikipedia
Carbonatation is a chemical reaction in which calcium hydroxide reacts with carbon dioxide and forms insoluble calcium carbonate: Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O The process of forming a carbonate is sometimes referred to as "carbonation", although this term usually refers to the process of dissolving carbon dioxide in water.

(a) Calcium reacts with cold water to form calcium hydroxide along with evolution of hydrogen gas. (b) The piece of calcium metal starts floating in water because the bubbles of hydrogen gas formed during the reaction stick to its surface.
Calcium | Ca (Element) - PubChem
The metal has a silvery color, is rather hard, and is prepared by electrolysis of fused chloride and calcium fluoride (to lower the melting point). Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame.

Calcium metal reacts readily with water according to the equation: Ca + 2H2O Ca(OH)2 + H2 If 3.23 g of Ca react with 2.33 g of H2O, what is the limiting reactant in this reaction? (Be sure to show your work.)
Carbonate chemistry — Science Learning Hub
Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases. The increased solubility of calcium carbonate in rainwater saturated with carbon dioxide is the driving force behind the erosion of limestone rocks, leading to the formation over long periods of time of caverns, caves, stalagmites and stalactites.
What Metals React With Water to Produce Hydrogen? | …
When sodium metal reacts with water, the resulting heat melts the metal almost immediately into a grey-silver ball. The hydrogen gas evolved during this reaction propels the ball rapidly across the surface of the water, leaving a white trail of sodium hydroxide that eventually dissolves into a clear solution.
Acids, Bases and Salts
Calcium hydroxide gives calcium carbonate and water when it reacts with carbon dioxide. Note : When an acid reacts with a metal oxide, both neutralize each other.
