Why do silver articles turn black when kept in the open for few days and what is the name of black substance formed?
Silver Oxide forms on the surface. The only metal that does not Oxidize is Gold.
What is the correct name for Ag2O?
It is silver oxide that is Ag2O.
What is the equation for the thermal decomposition of zinc carbonate?
thermaldecompositionMetal Carbonate ----------> Metal Oxide + Carbon dioxide
How would you thermally decompose silver oxide?
Silver oxide (Ag2O) can be thermally decomposed in a process known as thermal decomposition. This process involves heating the silver oxide to temperatures between 400 and 600 degrees Celsius. To do this you will need a furnace crucible and heating source. Here is a step-by-step guide on how to thermally decompose silver oxide:Place the silver oxide in a crucible and place the crucible in the furnace.Heat the silver oxide to 400-600 degrees Celsius depending on the desired reaction outcome.Allow the silver oxide to heat for up to an hour depending on the amount of silver oxide being thermally decomposed.Once the silver oxide has reached the desired temperature turn off the heating source and allow the furnace to cool.Once the furnace has cooled remove the crucible and inspect the silver oxide. The silver oxide should now be in two parts: silver and oxygen.Thermal decomposition of silver oxide is a relatively simple and safe process and can be used to create silver and oxygen from silver oxide.
What happens when silver reacts with air?
it tarnishes and can make a dull layer of metal oxide on the surface"tarnish" or oxidation.

Is CaO a metal oxide or non metal oxide?
Calcium is a metal, therefore this is a metal oxide.
Why do silver spoons turn black?
When silver interacts with oxygen it creates silver oxide. It is a similar reaction as to when water interacts with iron.

Why ag turn black on contact with air?
Silver tarnishes in air because it reacts with the oxygen to form silver oxide.
Is phosphoros a metal oxide or a non metal oxide?
Phosphorus is not an oxide. It is an element. It is a nonmetal.
What would you tell engineer who has suggested a design for a new battery using silver for both electrodes?
There must be a difference between the electrodes. If both are silver metal the voltage will be zero. I don't know if it works with silver like it does with lead, but oxidizing the metal of one electrode might make a workable battery (a silver/silver oxide battery like the lead/lead oxide of the lead acid battery).

When oxygen is bonded to a metal it forms?
The oxidation of a metal produces a metal oxide. For example, calcium + oxide -> calcium oxide
