(b)writethe balanced chemical equation for
(i) formation of x
(ii) dissdution of x in water
(iii) Formation of y

Answer:
Chemical formula of compound X is MgO. If the burning ribbon is placed in nitrogen gas chamber, magnesium reacts with nitrogen and forms magnesium nitride (Mg3N2). ... If magnesium oxide is dissolved in water, it forms magnesium hydroxide.

→2MgO
Therefore X is MgO.
Burning magnesium ribbon reacts with nitrogen(N
