Silver oxide decomposition. Silver oxide being heated to form silver. Silver oxide is a dark brown or black powder. The oxides of unreactive metals, such as silver, are capable of being reduced to their metals by heat alone because less reactive metals do not tend to form stable compounds. The reaction taking place is: 2Ag2O -> 4Ag + O2.
