1. Write a balanced equation for the reaction of calcium phosphide with water to produce phosphine and calcium hydroxide, in a atmosphere of carbon dioxide at 0C and a pressure of 4.8mm Hg. At STP carbon dioxide has a density of 1.96g/litre, and phosphine has a density of 1.53g/litre. Liquid water is used in the reaction.
2. Write a balanced equation for the reaction of a phosphine explosion in air to form solid diphosphorus pentoxide (P2 O5) and steam.
3.Write a balanced equation for the reaction of the breakdown of phosphoric acid in water.
This solution provides chemical equations.
