Dinitrogen pentoxide ,a colourless deliquescentsolid is ,prepared byA.

1.	Dinitrogen pentoxide ,a colourless deliquescentsolid is ,prepared byA. reaction `NH_(4)NO_(3)` with an excess of oxygen `(NH_(4)NO_(3)+2O_(2)rarrN_(2)O_(5)+2H_(2)O)`B. dehydrating `HNO_(3)` with `P_(4)O_(10)` at a high temperature `(4HNO_(3)+P_(4)O_(10)rarr4HPO_(3)+2N_(2)O_(5))`C. dehydrating `HNO_(3)` with `CaO` at a high temperature `(2HNO_(3)+CaOrarrN_(2)O_(5)+Ca(OH)_(2))`D. reacting `NaNO_(3)` with `N_(2)O_(4) (NaNO_(3)+N_(2)O_(4)rarrN_(2)O_(5)+NaNO_(2))`
Answer» Correct Answer - 2 `N_(2)O_(5)`is prepared by distilling concentrated nitric with phosphorus pentoxide in a glass apparatus: `{:(2HNO_(3) rarr H_(2)O+N_(2)O_(5)),(P_(2)O_(5)+H_(2)O rarr 2HPO_(3)),(bar(P_(2)O_(5)+2HNO_(3) rarr 2HPO_(3)+N_(2)O_(5))):}` It is also prepared by the action of dry chlorine on solid silver nitrate at`95^(@)C` `4AgNO_(3)+2Cl_(2)rarr 4AgCl +2N_(2)O_(5) + O_(2)`
