Why can't krypton and xenon separate during the separation of gases in the air?

Answers

Answer:

The remaining gas is a mixture of argon, neon, krypton, and xenon. Because these elements are chemically very unreactive, chemical means cannot be used to separate them.

Explanation:

Answer:

They're in Group 0 as they have full outer shells meaning they are chemically unreactive as they already have full outer shells meaning they don't want to lose or gain any electrons. Thus, they can't separate during the separation of gases in the air.

Which Lewis electron-dot diagram correctly represents the reactant containing nitrogen in the equation?

Answers

Since its asking for just the reactant, you can ignore the whole left side. Now since its only asking for the reactant containing Nitrogen, you can ignore the NaHCO3 since it doesnt have nitrogen.
That leaves us with drawing the structure of NH4Cl.
This was a tough one for me to find, as I kept drawing Ammonia instead and couldnt figure out how to fit in the extra Hydrogen and Chlorine. Luckily, this Y!A answer explains it, its due to a hydrogen bond

Option (1) represents the Lewis electron-dot diagram correctly containing nitrogen in the equation.

Lewis Structure is a very simplified representation of the valence shell electrons in a molecule.  It is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms.

Valence electrons are given by hydrogen atoms = [tex]1\times3=3[/tex]

Valence electrons are given by nitrogen atom = [tex]5\times1=5[/tex]

Total valence electrons = 3 + 5 = 8

So, the calculation above is shown only the first option. So, (1) Lewis electron-dot diagram correctly represents the reactant containing nitrogen in the equation.
