A `5.0 g` quantity of white phosphorus was burned in an excess of oxygen and the product was dissolved in water to make `250.0 mL` solution.  (a) Write balanced equations for the reaction.  (b) When the solution was treated with an excess of aqueous `Ca(NO_(3))_(2)`, a white precipitate was obtained. What was it and how much it formed?  (c ) The precipitate in part (b) was removed and the solution was treated with an excess of `Zn`, yielding a colourless gas collected at `20^(@)C` and `742 mm of Hg`. What was the gas and how much volume of it was formed?
