Choose the correct answer from the options given below :
Ammonia reacts with excess chlorine to form
Look at the following reaction :
A. Nitrogen + metal → compound X
B. X + water → ammonia + another compound

(i) One metal that can be used for reaction in A is magnesium.
(a) Write the formula of the compound X, that is formed.
(b) Write the balanced equation for reaction B, where Xis the compound formed.
( c) Which property of ammonia is demonstrated by reaction C?
Ammonia burns in oxygen, as shown below.
\[\ce{4NH3 + 3O2 -> 2N2 + 6H2O}\]
