Ag2O
that means the silver nitrate reacted with the sodium hyroxide solution and sodium hydroxide and silver oxide was produced. this is called a double replacement reaction.
[155 (g Ag2O) / 231.8 (g Ag2O/mol Ag2O)] * 2 (mol Ag/mol Ag2O) == 310/231.8 mol Ag = 1.337 == 1.34 mole Ag
They form silver chloride and water, Ag2O + 2HCl = 2AgCl +H2O
Silver have high affinity toward halogen. Dry silver oxide (Ag2O) reacts with two molecules of (2RX) to give ether and 2AgX. Reaction will be: 2RX + Ag2O = ROR + 2AgX
Because Ag2O (as oxidator) is more reactive than FeO, so Fe (as reductor) can abstract the oxide O (O2-) from Ag2O according to electrochemical series (which says: Ag is less reactive to oxygen than Fe, Ag is a more 'noble' metal)Fe + Ag2O --> FeO + 2Ag
It yields to Ag2O+HI. So, H2O + 2AgI = Ag2O + 2HI.
2 AgBr (s) + 2 NH4OH (aq) --> Ag2O (s) + H2O (l) +2 NH4Br (aq) The reaction does not proceed rapidly as in the case of AgCl as AgBr is only slightly soluble in ammonium hydroxide. With more NH4OH, the brown/black Ag2O dissolves forming the soluble salt Silver Di-amine hydroxide: Ag2O (s) + 4 NH4OH --> 2 [Ag(NH3)2]OH + 3 H2O I suspect that this reaction is reversible and the loss of NH3 would push the reaction to the left, which may occur naturally with time. This is a major problem as the precipitated Ag2O can further react with NH4OH to form Silver nitride, Ag3N: 2 NH4OH (aq) + 3 Ag2O (s) --> 2 Ag3N (s) + 5 H2O Silver nitride can be a highly sensitive and powerful contact explosive, even when in solution. This has been ascribed to be the cause of many injuries, and as such, solutions of [Ag(NH3)2]OH should not be stored for safety concerns.
2HgO --> 2Hg + O2 is a decomposition reaction, in which Mercury oxide is decomposed into the element mercury and oxygen gas. A decomposition reaction is one in which a more complex substance is broken down into its simpler components.

2 Ag2O --> 4Ag + O2Start with the siplest formula's without coefficients: Ag2O --> Ag + O2first balance O for two atoms: 2 Ag2O --> Ag + O2Then balance Ag for 2x2 = 4 atoms: 2 Ag2O --> 4 Ag + O2
