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 continues and burns to form a compound y (1) write the chemical foamulae of x and y (2) write the balanced chemical equation when x is dissolved in water

Answer 1

1. magnesium oxide- MgO

2. 2mg+o2=2mgo

Answer 2

Answer:

2mg+ o2 --> 2MgO

(compound X)

MgO + N2 ----> Mg3N2 + o2

(compound Y)

balanced equation--

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