Upon burning Mg in air, magnesium oxide and magnesium nitride are formed. The correct statement about magnesium nitride is: O a. It does not react with water. O b. It has the empirical formula MgN. O c. It reacts with water to give Mg(OH)2 and NH3. d. It has the empirical formula Mg2N3. e. Existence of magnesium nitride in the sample will lead to higher O to Mg ratio.
