A) \[N{{H}_{3}}\]
B) \[{{N}_{2}}\]
C) \[P{{H}_{3}}\]
D) MgO
Correct Answer: A
Solution :
When magnesium is heated to redness in an atmosphere of nitrogen then magnesium nitride is formed. \[3Mg+{{N}_{2}}\xrightarrow{{}}\underset{magnesium\text{ }nitride}{\mathop{M{{g}_{3}}{{N}_{2}}}}\,\]and when magnesium nitride is treated with water it gives ammonia. \[M{{g}_{3}}{{N}_{2}}+6{{H}_{2}}O\xrightarrow{{}}3Mg{{(OH)}_{2}}+2N{{H}_{3}}\]You need to login to perform this action.
