What is the chemical formula of silver oxide?
Ag2OSilver oxide / Formula
What is Ag2O?
A common base for this is silver oxide (Ag2O) although many other bases will also work.
How do you make Ag2O?
Silver oxide can be produced by allowing elemental silver to react with oxygen in the air at temperatures under 195° C. This reaction can be reversed by heating the silver oxide to temperatures over 195° C. The oxygen in the silver oxide will be released as oxygen gas, and elemental silver will remain as a solid.

What is the formula unit of potassium oxide?
K2O
The formula unit for potassium oxide is K2O , which is also the empirical formula. The formula unit for potassium peroxide is K2O2 . The ratio of K+ ions to O22− ions is 1:1 , so KO is the empirical formula for potassium peroxide.
What type of reaction is silver oxide?

What happens to silver bromide in light?
Light decomposition reaction. Silver bromide is a light-sensitive compound that is it gets decomposed when exposed to light. So when silver bromide is exposed to sunlight, it gets decomposed to give silver metal and bromine gas is liberated.
What is the charge for silver bromide?
+e
When the atoms combine to form silver bromide the electron from the outer shell of the silver atom moves over to the bromine and so gives it an overall negative charge (—e). The loss of the electron from the silver makes it have an overall positive charge (+e).
What is the formula unit of K and O?
The formula unit for potassium oxide is K2O , which is also the empirical formula. The formula unit for potassium peroxide is K2O2 . The ratio of K+ ions to O22− ions is 1:1 , so KO is the empirical formula for potassium peroxide.
