Answer:
The nitrogens are both sp3 hybridized. Their bonds are formed by sp overlaps. The carbon and oxygen are sp2 hybridized. The double bond with oxygen is produced by a sp2 overlap to form the sigma component and a probital overlap to form the pi component. The bonds with hydrogen are formed by sp2 overlaps.

Dear, your answer is
solubility is affected by current concentration, mechanical disturbance, temperature and pressure. So the answers are:
- Increasing temperature decreases the solubility of gases.
- Stirring increases the solubility of solids.
- Increasing pressure increases the solubility of gases.
- Decreasing the amount of solvent decreases the solubility of solids, liquids, and gases.

Explanation:
Hello,
In this case, by using the Henderson-Hasselbach equation one could compute the pH considering that the pKa of hydrofluoric acid, HF, is 3.14:
![pH=pKa+log(\frac{[base]}{[acid]} )](https://tex.z-dn.net/?f=pH%3DpKa%2Blog%28%5Cfrac%7B%5Bbase%5D%7D%7B%5Bacid%5D%7D%20%29)
Whereas the concentration of the base and acid are computed by considering the mixing process with a total volume of 300 mL (0.3 L):
![[HF]=\frac{0.005molHF}{0.3L}=0.017M](https://tex.z-dn.net/?f=%5BHF%5D%3D%5Cfrac%7B0.005molHF%7D%7B0.3L%7D%3D0.017M)
![[NaF]=\frac{0.02molHF}{0.3L}=0.067M](https://tex.z-dn.net/?f=%5BNaF%5D%3D%5Cfrac%7B0.02molHF%7D%7B0.3L%7D%3D0.067M)
Therefore, the pH turns out:
Regards.
