For the following question two statements are given – one labelled Assertion (A) and the other labelled Reason (R).Assertion: Magnesium ribbon burns with a dazzling flame in air.Reason: A white substance magnesium nitride is formed.Select the correct answer to the question.

Assertion: Magnesium ribbon burns with a dazzling flame in air.Reason: A white substance magnesium nitride is formed.

A magnesium ribbon is burnt in oxygen to give a white compoundX accompanied by emission of light. If the burning ribbon is nowplaced in an atmosphere of nitrogen, it continues to burn andforms a compound Y.(a) Write the chemical formulae of X and Y.(b) Write a balanced chemical equation, when X is dissolved inwater
