Question

a magnesium ribbon is burnt in oxygen to give a white compound x accompanied by emmission of light. if the burning ribbon is now placed in an atmosphere of nitrogen it continues to burn and forms a compound y.
a.write the chemical formula of x and y
b. write a balanced chemical equation when x is dissolved in water

Answer 1

for x>> 2Mg+O2>2MgO

for y>>3Mg+N2>Mg3N2

when x is dissolved in water(h2o) i.e.

MgO+H2O>Mg(OH)2[magnesium hydroxide]

Answer 2

Answer:

Explanation:

The Compound 'X' is Magnesium Oxide(MgO) which is a white compound, that burns with dazzling white light....

Eqn: Mg+O2-> MgO....

The compound 'Y' is Magnesium Nitride(Mg3N2)......

When MgO dissolved in water:

MgO+H2O-> Mg(OH)2.....
