Mg3N2 + 3 H2O --> 2 NH3 + 3 MgO . A new hydrated magnesium borate, Mg(H2O)6B4O5(OH)4(H2O)3, was synthesized successfully by a facile slow evaporation method. Mg 3 N 2 (s) + 6 H 2 O (l) → 3 Mg (OH) 2 (aq) + 2 NH 3 (g) In fact, when magnesium is burned in air, some magnesium nitride is formed in addition to the principal product, magnesium oxide. In the case of a compound with a name ending in "-ol", the something else is likely oxygen. Magnesium metal dissolves readily in dilute sulphuric acid to form solutions containing the aquated Mg(II) ion together with hydrogen gas, H 2. Compound states [like (s) (aq) or (g)] are not required. Magnesium react with nitric acid to produce nitrate magnesium, nitrogen and water. You can use parenthesis or brackets [].
