Question

A magnesium ribbon is burnt in oxygen to give a white compound X accompanied by emissions of light.If the burning ribbon is now placed in an atmosphere of nitrogen,it continues to burn and form a compound Y.
a)Write the chemical formulae of X and Y.
b) Write a balanced chemical equation,when X is dissolved in water.

Answer 1

Hi Friend,

Here is your answer,

X is Magnesium oxide 
Y is Magnesium Nitride.

The balanced equation for X is:-

MgO(s) + H₂0(l)=========>> Mg(OH)₂



Hope it helps you!

Answer 2

Answer:

2mg+ o2 --> 2MgO

(compound X)

MgO + N2 ----> Mg3N2 + o2

(compound Y)

balanced equation--

MgO + h2o ---> mg(oh)2
