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 to born and forms a compound why write the chemical formula of X and Y B write a balanced chemical equation when X is dissolved in water ​

Answer 1

Magnesium ribbon burns in oxygen(O2) to form magnesium oxide(MgO).

2Mg+O2 →2MgO

Therefore,

☑️☑️X is MgO☑️☑️

When MgO is dissolved in water following reaction takes place:

MgO+H2O→Mg(OH)2
