Get Started However, the reaction is thermodynamically and kinetically less favourable than the reaction with molecular oxygen ($\ce{O2}$). However, again in the presence of water vapor, the nitride is not stable possibly reacting as follows: $\ce{Mg3N2(s) + 6 H2O(l) -> 3 Mg(OH)2(aq) + 2 NH3(g)}$. Decomposition reactions involve the breaking down of compounds to form smaller molecules or elements. Those metal carbonates which do decompose leave a residue of the metal oxide and evolve carbon dioxide in the process, eg: At an elementary level, the relative thermal stability of the carbonates of the metals cannot easily be explained in terms of simple ideas of bonding in these compounds. More details can be found in the link but the conclusion was: Given that no evidence of $\ce{Mg3N2}$ formation could be found, it appears that the hydration step is not necessary and only makes the experiment more difficult. A cubic phase, close to that expected for the mixed metal nitride, was found in the . (b) The second step is the formation of solid calcium hydroxide as the only product from the reaction of the solid calcium oxide with liquid water. Fujian Zong, Chunzhan Meng, Zhiming Guo, Feng Ji, Hongdi Xiao, Xijian Zhang, Jin Ma, Honglei Ma, Explanation of Experiment: The oxidation or combustion of magnesium in air has long been used as a source of intense light in photography and for other photochemical reactions.
