Net Ionic Equation | Actforlibraries

Ca2+ and Na+ are positively charged ions, floating free in the water at a ratio of two Na+ ions for every one Ca2+ ion. Similarly, Cl- and (CO3)2- are negatively charged anions, also floating in the water, with twice as many Cl- ions as (CO3)2- ions. As soon as calcium chloride and sodium carbonate are dissolved in water, the ions float free.

Calcium phosphide - Wikipedia

Calcium phosphide (CP) is the inorganic compound with the formula Ca 3 P 2.It is one of several phosphides of calcium, being described as the salt-like material composed of Ca 2+ and P 3−.Other, more exotic calcium phosphides have the formula CaP, CaP 3, Ca 2 P 2, and Ca 5 P 8.. Ca 3 P 2 has the appearance of red-brown crystalline powder or grey lumps. Its trade name is Photophor for the

WebElements Periodic Table » Magnesium » …

Magnesium does not react with water to any significant extent. This is in contrast with calcium, immediately below magnesium in the periodic table, which does react slowly with cold water. Magnesium metal does however react with steam to give magnesium oxide (MgO) (or magnesium hydroxide, Mg(OH) 2, with excess steam) and hydrogen gas (H 2).

why does calcium starts floating when it reacts …

Dear student! Actually, when calcium reacts with water, the reaction is less vigorous and it forms calcium hydroxide with release of hydrogen gas, but the heat evolved is not sufficient for hydrogen gas to ch fire and so it sticks over the surface of calcium hydroxide and the wall of container which do not let the calcium hydroxide to sink and it continues to float on the water surface .
