Question

A magnesium ribbon is burnt in the air to give a white compound 'x' accompiaind by emissions of light. if the burning ribbon is now placed in an atmosphere of nitrogen. it continues to burn and forms a compound 'y'. 1) write chamical formulae of 'x'and'y'?
2) write a balanced chamical equation . when 'x' is dissolved in water.?​

Answer 1

Answer:

Complete answer:

When oxides of alkaline earth metal dissolve in water, the hydroxides of alkaline earth metal form. When a magnesium ribbon is burnt in oxygen a white compound magnesium oxide ${\text{MgO}}$ is formed accompanied by the emission of light. So, compound 'X' is magnesium oxide.
