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.

If 5.60g of a gas at 2.50atm dissolves in 3.5-l of water.
this means you probably have to multiply 5.60g*2 because 2.50atm go into 5.00atm twice 5.60g(2)= 11.2
Answer:
220.9g of water are required
Explanation:
The molar enthalpy of vaporization is defined as the heat released when 1 mole of water changes from liquid to gas.
For water, 1 mole releases 40.79kJ. To release 500kJ are necessaries:
500kJ * (1mol / 40.79kJ) = 12.26 moles are necessaries
To convert moles to grams we must use the molar mass (H2O = 18.02g/mol):
12.26 moles * (18.02g / 1 mol) =
<h3>220.9g of water are required</h3>
If my memory serves me well, correct answer looks like this: If a material, such as diamond, is very strong but gives way (ruptures) quickly when a crack forms, then it is considered <span>c.brittle</span>.
The answer has to be 22.4L
