1.	Magnesium metals burns in air to give a white ash . When this ash is treated with water , the odour of ammonia can be detected . Explain .
Answer» Solution :Mg burns in air to form MGO and `Mg_(3) N_(2)`. `2 Mg + O_(2) overset(Delta) (to) 2 MgO , 3 Mg+ N_(2) overset(Delta)(to) Mg_(3) N_(2)` Magnesium nitride on HYDROLYSIS with `H_(2)O` (moisture) GIVES `NH_(3)` . `Mg_(3)N_(2) + 6 H_(2)O to 3 Mg (OH)_(2) + 2 NH_(3)`
