Question

a magnesium ribbon is burnt in oxygen to give a white compound x accompanied by emmision of light .if the burning ribbon is now placed in an atmosphere of nitrogen,it continues to burn and forms a compound y.
1) write the chemical formulae of x and y .
2) write the balanced chemical equation when x is dissolved in watar.​

Answer 1

Answer:

When magnesium ribbon is burnt in oxygen, it forms magnesium oxide with emission of light and heat energy. 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)

(a) X is Magnesium Oxide - MgO and Yis Magnesium nitride - Mg3N2.

(b) MgO + H2O + Mg(OH)2

Answer 2

Answer:

please mark it as brainliest answer

x is magnesium dioxide(MgO) and y is Mg3N2

Explanation:

MgO+H2O= Mg(OH)2
