calcium came from a rock.

Yes, that's its source for plants and animals, but as a solution in water of limestone's & chalk's principle constituent, calcium carbonate.
Further back it derives from hydrolysis (a form of dissolution in water) of the calcium-silica compounds existing as minerals making up the igneous rock, granite. Thus released into the seas it can re-enter the complicated "rock cycle" by being taken up in the formation of limestone & chalk.
Ultimately, like every other chemical element on this planet and around the Universe, calcium is created by nuclear fusion in giant stars whose eventual death has the energy to initiate these reactions, and then to blow them out into Space in Supernovae bursts.
In hard water containing calcium chloride dissolved in distilled water, the ions present would be calcium (Ca2+) and chloride (Cl-). The calcium ions come from calcium chloride, while the chloride ions come from the dissociation of calcium chloride in water.
the 3 elements found in calcium sulfate are calcium,sulfur and oxygen
Ca+O=CaO
No, it is not. Calcium is a metal but calcium carbonate is not.
i believe my calculations with amnothisewis can card your difficulty with thinking up a scietific answer..... none but electrons!!!!1 Calcuim Carbonate CaCO3 Calcuim Sulphate CaSO4 Calcium Oxide CaO Calcium Fluride CaF2 Calcium Chloride CaCl2 Calcium Bromide CaBr2 Calcium Iodide CaI2 Calcium Cyanide CaCN And plenty more just connect Calcium with any negetive ion you can think off. Remember Calcium has a valance of +2
Calcium difluoride; Fluorspar; Acid spar the chemical formula is CaF2 (source: http://www.jtbaker.com/msds/englishhtml/c0374.htm)

Yo-yo means 'come back come back' in Tagalog, which is the Filipino language.
