The white coating on calcium metal is calcium that has reacted with the oxygen in the air to form calcium oxide
Calcium phosphate is typically white in color.
Yes. Calcium will quickly form a coating of calcium oxide on contact with air.
the precipitate is calcium sulfate (CaSO4) and its white in color
Calcium oxide (CaO) reacts with water to give a white alkaline solid called calcium hydroxide (Ca(OH)2).
Sensory nerves in your finger trigger minute electrical impulses which travel to your brain. Your brain then interprets those impulses as one thing or another and you say, "Hmm, that's what calcium metal feels like."
Calcium in its pure solid form appears as a silvery-white metal. However, when exposed to air, it quickly forms a dull gray oxide and nitride coating.
The white coating in a kettle is likely limescale, which is a deposit of calcium carbonate. It forms when hard water is boiled, leaving behind minerals on the kettle's surface. Regular descaling with vinegar or a commercial descaler can help remove this buildup.
As slaked lime is of calcium hydro oxide it takes time. when heat react with calcium hydro oxide the water of calcium get evaporated it become quick lime (calcium carbonate). as the water evaporated the carbon dioxide get a chance to react with calcium carbonate and forms white colour.....

Calcium is a solid, soft dull grey metal at room temperature :)
Calcium makes bones and teeth strong as it is like the enamel coating your teeth and bones.
The white outer coating on teeth is called enamel.

Because egg has calcium coating
The theoretical reason for using Ammonium thiosulfate, Dipropylene Glycol, and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes is their ability to be used as wetting agents.

In contact with air, calcium develops an oxide and nitride coating, which protects it from further corrosion.
Calcium phosphate is typically white in color.
