Answer:

436.8 mmHg.

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 0.93 atm

Pressure of N₂ (Pₙ₂) = 270 mmHg

Pressure of O₂ (Pₒ₂) =?

Next, we shall convert the total pressure to mmHg . This can be obtained as follow:

1 atm = 760 mmHg

Therefore,

0.93 atm = 0.93 × 760 mmHg / 1 atm

0.93 atm = 706.8 mmHg

Finally, we shall determine the pressure of the O₂. This can be obtained as follow:

Total pressure (Pₜ) = 706.8 mmHg

Pressure of N₂ (Pₙ₂) = 270 mmHg

Pressure of O₂ (Pₒ₂) =?

Pₜ = Pₙ₂ + Pₒ₂

706.8 = 270 + Pₒ₂

Collect like terms

706.8 – 270 = Pₒ₂

436.8 = Pₒ₂

Pₒ₂ = 436.8 mmHg

Thus, the pressure of O₂ is 436.8 mmHg

In water solution, the conjugate base of HF is __________
anastassius [24]

Answer:

The correct answer is : F^-

Explanation:

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

Acid after donating protons changes into conjugate base and base after accepting protons changes into conjugate acid.

So, when HF in water reacts, it form fluoride ions and hydronium ions. The recation is given as:

HF+H_2O\rightarrow F^-+H_3O^+

Here, HF is acting as a  Bronsted Lowry acid by donating proton and forms it conjugate base F^-, Where as water is acting as a  Bronsted Lowry base by accepting a proton and forms its conjugate acid H_3O^+.
