Answer:
A Reaction of decomposition is ocurred to hydrogen peroxide.
Explanation:
Hydrogen peroxide is a molecule that can break down into Hydrogen and Oxygen or decompose very slow under moderate temperature, as you can see in the image below, hydrogen peroxide has a high electronic cloud that makes it a great oxidizer.
The formula for Cs and S is Cs₂S.
For Cs and S,
Ions formed will be Cs⁺ and S²⁻
As cesium belongs to group 1A and sulfur belongs to group 6A. Therefore, the condensed electronic configuration is -
For Cs is [Xe} 6s¹ and for S is [Ne] 3s²3p⁴.
Cs have 1 valence electron and S have 6 valence electrons.
Hence to attain a stable electronic configuration, both two Cs atoms lose one electron and form Cs⁺ and these two electrons will be accepted by one S atom to form S²⁻.
Therefore the formula for the compound is Cs₂S as Cs donate 1 electron and S will accept 2 electrons from Cs.
The formula is Cs₂S.
