To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.1-L bulb, then filled

Answer:

Nitrogen, $N_2\\$

Explanation:

Hello,

This is a clear example of what the ideal gas equation is used for, thus, from its mathematical definition:

$PV=nRT$

One can spell it out in terms of mass and molar mass:

$PV=\frac{m}{M}RT$

Now, solving for the molecular mass, $M$ :

$M=\frac{mRT}{PV} =\frac{9.5g*0.082\frac{atm*L}{mol*K}*297.15K}{2.00atm*4.1L}\\ M=28.23g/mol$

Now, by taking into account that the gas is diatomic, the matching gas turns out to be nitrogen.

Best regards.

Answer:

Rubidium= [Kr] 5s^1

Calcium= [Ar] 4s^2

Aluminium= [Ne] 3s^2 3p^1

Explanation:

A noble gas configuration begins with the elemental symbol of the last noble gas prior to the atom. The symbol is then followed by the remaining electrons.

Hope this helped! good luck :)
