Answer:
27.9 g
Explanation:
CsF + XeF₆ → CsXeF₇
First we <u>convert 73.1 g of cesium xenon heptafluoride (CsXeF₇) into moles</u>, using its<em> molar mass</em>:
- Molar mass of CsXeF₇ = 397.193 g/mol
- 73.1 g CsXeF₇ ÷ 397.193 g/mol = 0.184 mol CsXeF₇
As <em>1 mol of cesium fluoride (CsF) produces 1 mol of CsXeF₇</em>, in order to produce 0.184 moles of CsXeF₇ we would need 0.184 moles of CsF.
Now we <u>convert 0.184 moles of CsF to moles</u>, using the <em>molar mass of CsF</em>:
- Molar mass of CsF = 151.9 g/mol
- 0.184 mol * 151.9 g/mol = 27.9 g
Since the volume decreased, it means that the pressure is going to rise. Thus, the equilibrium of the reaction will shift in the direction that has the least amount of moles.
Explanation:
neon has 8valence electrons
chroline has 7 valence electrons
nitrogen has 5 valence electrons
oxygen has 6 valence electrons
so neon has the most valence elctrons

It's oxidation number is related to its charge.
Since this atom's charge is very negative in the 1st molecule, it is more electronegative. Which means the other atom is less electronegative.
In the 2nd molecule, it has a positive charge, so THIS atom is less electronegative. Or, you can say the OTHER atom is more electronegative.
