When silver oxide is heated in the presence of a reducing agent such as hydrogen or carbon monoxide, the oxygen atoms in the silver oxide are removed, leaving behind pure silver. The reaction can be represented by the following equation: 2Ag2O(s) + heat → 4Ag(s) + O2(g) This process is commonly used in the production of silver from silver oxide in industrial settings. **
