The product formed when Ag2O decompose is O2 ( answer c)
explanation
Decomposition involve separation of a single chemical compound into two ore more elemental parts Ag2O decomposes to yield Ag and O2
that is 2Ag2O→ 4Ag + O2
2 moles of Ag2O decomposes to yield 4 moles of Ag and 1 mole of O2

Explanation:
Hello!
In this case, since the net ionic equations are ionic representations of the molecular equation in which the spectator ions (those at both reactants and products sides) are cancelled out, we first write the complete ionic equation for this reaction, considering that the solid silver chloride is not ionized due to its precipitation:
Whereas the nitrate and sodium ions are cancelled out for the aforementioned reason as they are the spectator ions, to obtain:
Which is the required net ionic equation.
Best regards!
Answer:
The answer is A
Explanation:
Let's break this down. . .
-The lower the pH, the more acidic.
-So, the pH of 2 is more acidic than 3.
-Then, it's pretty obvious that the concentration with more acidic substance will be greater or higher than the other substance.
- As a result, the concentration of pH 2 will be greater or higher than the concentration of pH 3.
If you want the "mathematical" form then here:
Concentration
A pH of 2 would be 10 to the -2; 10^-2 which will equal 0.01
A pH of 3 would be 10 to the -3; 10^-3 which will equal 0.001
Which one is greater than the other?
A substance with a pH of 2 has a 10 times higher concentration of H* than a substance with pH of 3.
