What is the chemical formula for the ionic compound formed
网页2014年4月25日 · Calcium nitride is a red-brown, crystalline solid made up of calcium and nitrogen. Its chemical formula is Ca_3N_2. The ratio will be determined by the charges of the ions. (3 x Ca2+) = +6 (2x N3-) = -6 The net charge of the compound will be zero. Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be …
How do you write "calcium + nitrogen -> calcium nitride"? - Socratic
网页2015年12月28日 · The calcium ion is a 2+ ion, or Ca2+. The nitride ion is a 3- ion, or N3−. As such, to balance the charges we require 3x calcium ions for every 2x nitride ions, or Ca3N2. ∴ Ca(s) +N 2(g) → Ca3N 2(s) Balancing the equation, then, you will notice that the number of nitrogens on each side balances However, on the left side of the equation we ...
