Question

A magnesium ribbon is burnt in oxygen to give a white compound X accompanied by emission of light.if the burning ribbon is now placed in an atmosphere of nitrogen.it continuous to burn and forms a compound Y.
A) write the chemical formulae for X and Y.
B) write a balanced chemical equations

Answer 1

A) the chemical formula for compound X is mgo and for compound Y is Mg3N2.
B) the balanced chemical equation are as follow:
2MG + O2 = 2MGO AND
3MG + N2 = MG3 N2

Answer 2

Answer:

2mg+ o2 --> 2MgO

(compound X)

MgO + N2 ----> Mg3N2 + o2

(compound Y)

balanced equation--

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