Thermal 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.
