The highlighted atoms have sp2 - sp3 hybridization. The highlighted atoms are carbon and nitrogen as shown.
The structure of Xanthine is shown in the image attached to this answer. The indicated atoms are Carbon and nitrogen as shown. Let us remember that hybridization has to do with the mixing of atomic orbitals to form appropriate hybrid orbitals that are suitable for overlap with orbitals of other atoms.
The highlighted carbon atom is sp2 hybridized because it has a carbon nitrogen double bond while the highlighted nitrogen atom is sp3 hybridized. Therefore, the highlighted atoms have sp2 - sp3 hybridization.

Angular Velocity is the answer
Answer:
V = 20.97 L
Explanation:
Given data:
Mass of nitrogen = 23.4 g
Pressure of gas = 750 mmHg (750/760 = 0.99 atm)
Temperature of gas = 28°C (28+273= 301K)
Volume of gas = ?
Solution:
First of all we will calculate the number of moles of gas.
Number of moles = mass / molar mass
Number of moles = 23.4 g/ 28 g/mol
Number of moles = 0.84 mol
Now we will calculate the volume:
PV = nRT
V = nRT/P
R = general gas constant = 0.0821 atm.L/mol.K
V = 0.84 mol× 0.0821 atm.L/mol.K× 301 K / 0.99 atm
V = 20.76 L/0.99
V = 20.97 L
