Magnesium nitrate reacts with alkali metal hydroxide to form the corresponding nitrate: Mg(NO 3 ) 2 + 2 NaOH Mg(OH) 2 + 2 NaNO 3 . Form supplied in: greenish/yellow solid. Two possibilities that I can think of are: I don't think that composition is the answer because on average the atmosphere of Earth has more nitrogen than oxygen, so I think that the answer may be temperature. The difference is surprisingly smaller than I would have expected, even taking into account that the $\ce{Mg3N2}$ lattice is more strongly bound than the $\ce{MgO}$ lattice. We have performed and supervised this experiment many times and have never seen any evidence of nitride formation. How does one decompose any magnesium nitride Expert Answer 86% (7 ratings) Magnesium nitride dec I think this is one of the first methods of obtaining argon from air. In the case of minor heating in the presence of an 'earth atmosphere' per Wikipedia, to quote: Magnesium occurs naturally only in combination with other elements, where it invariably has a +2 oxidation state. In this case, I would believe in the first reference more than the Wiki article. pH = 4.40 It has an anion valency of (3-). NOTE: Wikipedia mentions a contrary result. This is not unreasonable given that the temperature of burning Mg is much greater than the 850oC noted above and although Mg3N2burns in O2to form MgO, the rapid cooling of the ash might preserve any nitride present. the Pandemic, Highly-interactive classroom that makes Because of the toxicity of lead compounds, it may be best to leave lead carbonate out with less reliable classes.
