WebWrite the net ionic equation for the equilibrium that is established when calcium cyanide is dissolved in water. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. At temperatures around 600 °C, calcium cyanide converts to calcium cyanamide: Ca(CN)2 → CaCN2 + C It is suspected that this reaction is one step in the conversion of calcium carbide with nitrogen gas. The ratio of calcium cyanide to calcium cyanamide is sensitive to the presence of alkali metal halides, such as sodium chloride.
