Neither. It is classified as a compound.
Limestone is not a metal, it is a type of rock.
Calcium
Coal, metal ores, limestone.
Calcium is a reactive metal whose compounds make up limestone, chalk, cement and teeth. Drinking milk is one way to get this mineral.
with instruments for sculpture, even with softer metal instruments for stonecarving.
Alcatraz is made of sandstone,rock,limestone and natural vegetation.
Calcium
It is unlikely that calcium chloride crystals are made from calcium metal because calcium is a rare and very expensive metal, also very susceptible of corrosion in normal air.It is much easier to start with limestone (CaCO3) and dissolve it with hydrochloric acid. Carbon dioxide is released and the excess of water should be evaporated after filtering of the undissolved particles of the limestone impurities.(CaCO3)s + (impurities of limestone)s + (HCl)l => (CaCl2)s + (CO2)g + (H2O)evap ++ [impurities of limestone]filter
The formula for limestone is CaCO3 and hydrocloric acid is HCL. Therefore they undergo a acid + metalcarbonate reaction. acid + metal carbonate -> salt +water + carbon di oxide. So when limestone reacts with HCl it prodcues salt (CaCl2) , water (H2O) and carbon di oxide (CO2(bubbles)). thus limestone reacts with HCl
Calcium is the metallic component of the substance limestone. Limestone, or calcium carbonate, is an example of a sedimentary rock.
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
