How do you write "calcium + nitrogen -> calcium nitride
Dec 28, 2015· 3Ca_((s)) + N_(2(g)) -> Ca_3N_(2(s)) Calcium is a metal, so its formula will simply be "Ca" . Nitrogen is a diatomic molecular compound, making it "N"_2 . Since calcium nitride is an ionic compound, by evaluating its constituent ions we can determine its formula. The calcium ion is a 2+ ion, or "Ca"^(2+). The nitride ion is a 3- ion, or "N"^(3-)". As such, to balance the charges we require 3x

Thermal decomposition of metal carbonates | Resource | RSC
Those metal carbonates which do decompose leave a residue of the metal oxide and evolve carbon dioxide in the process, eg: ZnCO 3 (s) → ZnO(s) + CO 2 (g) At an elementary level, the relative thermal stability of the carbonates of the metals cannot easily be explained in terms of simple ideas of bonding in these compounds.
Periodic Table of Elements: Calcium - Ca
Calcium is an essential component shells, bones, teeth and plant structures. Additional Notes: Calcium was prepared as lime by the Romans under the name calyx in the 1st century A.D., but the metal was not discovered until 1808. Berzelius and Pontin prepared calcium amalgam by electrolizing lime in mercury.
