Calcium (Ca) - Properties, Appliions

11.07.2013· Calcium is the third most abundant metal on the earth’s crust. It is trimorphic in structure and its hardness is greater than that of sodium. It is less chemically reactive than alkaline metals. The atomic nuer of calcium is 20 and is represented by Ca.

Metal compound A reacts with dilute …

The end product is calcium chloride and the gas formed extinguishes a burning candle, it is CO2, the metal compound A must be calcium carbonate. Hence, the reaction between calcium carbonate and hydrochloric acid is as follows:CaCO3 + HCl → CaCl2 + CO2 + H2OCalcium Calciumcarbonate chloride

It''s Elemental - The Element Calcium

Although calcium is the fifth most abundant element in the earth''s crust, it is never found free in nature since it easily forms compounds by reacting with oxygen and water. Metallic calcium was first isolated by Sir Humphry Davy in 1808 through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO).
