True, a person can have free floating anxiety that can trigger a panic attack without there being a specific stimulus.
Answer is: same orbital, but have different spin directions.
The principal quantum number (n) is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state.
For principal quantum number n=2:
1) azimuthal quantum number (l) can be l = 0...n-1:
l = 0, 1.
The azimuthal quantum number determines its orbital angular momentum and describes the shape of the orbital.
2) magnetic quantum number (ml) can be ml = -l...+l.
ml = -1, 0,+1.
Magnetic quantum number specify orientation of electrons in magnetic field and number of electron states (orbitals) in subshells.
3) the spin quantum number (ms), is the spin of the electron.
ms = +1/2, -1/2.
Answer : The mass of 
is, 295.323 grams
Solution :
First we have to calculate the moles of 
.
Now we have to calculate the moles of NaBr.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react with 2 moles of
So, 2.87 moles of react with 2.87 moles of
Now we have to calculate the mass of NaBr.
Therefore, the mass mass of is, 295.323 grams
