\nSilver oxide undergoes thermal decomposition.
\n<\/section>\n
\nThermal decomposition is the breakdown of a compound by heating. Silver oxide (Ag2O) is relatively unstable and decomposes upon heating into silver metal and oxygen gas (2Ag2O(s) -> 4Ag(s) + O2(g)). Zinc oxide (ZnO) and Magnesium oxide (MgO) are stable oxides that do not decompose easily upon heating under normal conditions.
\n<\/section>\n
\nThe ease of thermal decomposition of metal oxides is related to the reactivity of the metal. Oxides of less reactive metals (like silver, mercury, gold) decompose more easily than oxides of more reactive metals (like magnesium, zinc, calcium).
