calcium metal reacts with water equation in greece
Calcium: Chemical reactions | Pilgaard Elements
At room temperature, calcium reacts with oxygen, forming a thin layer of CaO, that protects the metal from further oxidation. Calcium can be ignited and will when burning react with both oxygen and nitrogen forming calcium oxide, CaO, and calcium nitride, Ca 3 N 2 .

Determination of Calcium Ion Concentration
calcium ions changing colour from blue to pink/red in the process, but the dye–metal ion complex is less stable than the EDTA–metal ion complex. As a result, when the calcium ion–PR complex is titrated with EDTA the Ca2+ ions react to form a stronger
calcium | Definition, Properties, & Compounds | Britannica
Calcium constitutes 3.64 percent of Earth’s crust and 8 percent of the Moon’s crust, and its cosmic abundance is estimated at 4.9 × 10 4 atoms (on a scale where the abundance of silicon is 10 6 atoms). As calcite (calcium carbonate), it occurs on Earth in limestone, chalk, marble, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many marine animals.
