Question

A magnesium ribbon is burn in oxygen to give a compound x are combined by imission of light if the burning ribbon now placed in atmosphere of nitrogen and form y write the chemical formula of x and y

Answer 1

Answer:

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 2

Answer:

2mg+ o2 --> 2MgO

(compound X)

MgO + N2 ----> Mg3N2 + o2

(compound Y)

balanced equation--

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