1.	All ammonium salts on heating with sodium hydroxide produce ammonia gas. From which ammonium salt, can maximum amount of ammonia be obtained ?
Answer» `0.5 mol (NH_(4))_(3)PO_(4)` `0.5 mol (NH_(4))_(2)SO_(4)` `1.0 mol NH_(4)Cl` `1.0 mol NH_(4)NO_(3)` Solution :`{:(underset("0.5 mol")((NH_(4))_(3)PO_(4)),-=,underset("1.5 mol")(2NH_(3))),(underset("0.5 mol")((NH_(4))_(2)SO_(4)),-=,underset("1.0 mol")(2NH_(3))),(underset("1.0 mol")(NH_(4)Cl),-=,underset("1.0 mol")(NH_(3))),(underset("1.0 mol")(NH_(4)NO_(3)),-=,underset("1.0 mol")(NH_(3))):}` `(NH_(4))_(3)PO_(4)` can give MAXIMUM mass of ammonia GAS.
