A mixture of He He , N 2 N2 , and Ar Ar has a pressure of 24.1 24.1 atm at 28.0 28.0 °C. If the partial pressure of He He is 301
Karo-lina-s [1.5K]

Answer:

16.5 atm

Explanation:

<em>A mixture of He, N₂, and Ar has a pressure of 24.1 atm at 28.0 °C. If the partial pressure of He is 3013 torr and that of Ar is 2737 mm Hg, what is the partial pressure of N₂?</em>

The total pressure of a gaseous mixture is equal to the sum of the partial pressures.

P = pHe + pN₂ + pAr

pN₂ = P - pHe - pAr [1]

We need to express pHe and pAr in atm.

pHe=3013torr.\frac{1atm}{760torr} =3.96atm

pAr=2737mmHg.\frac{1atm}{760mmHg} =3.60atm

From [1],

pN₂ = 24.1 atm - 3.96 atm - 3.60 atm = 16.5 atm

Please explain how to find each answer solution.
svp [43]

Explanation:

1) Based on the octet rule, iodine form an <u>I</u>⁻ ion.

Therefore,

Option E is correct ✔

2) The electronic configuration of the sulfide ion (S²⁻) is :

₁₆S = 1s² 2s² 2p⁶ 3s² 3p⁴ or [Ne] 3s² 3p⁴

₁₈S²⁻ = 1s² 2s² 2p⁶ 3s² 3p⁶ or [Ne] 3s² 3p⁶

Therefore,

Option E is correct ✔

3) valence shell electron of

Halogens = 7

Alkali metal = 1

Alkaline earth metal = 2

Therefore,

Option D is correct ✔

4) Group 2 element lose two electron in order to achieve Noble gas configuration.

And here Group 2 element is Sr

Therefore,

Option B is correct ✔

5) Group 13 element lose three electron in order to achieve Noble gas configuration.

And here Group 13 element is Al

Therefore,

Option B is correct ✔

6) For a given arrangements of ions, the lattice energy increases as ionic radius <u>decreases</u> and as ionic charge <u>increases</u>.

Therefore,

Option A is correct ✔

By mistake, you added salt instead of sugar to the<br> oil. How can you remove the salt?
Ghella [55]

Explanation:

To remove the salt from the oil, I will add water to dissolve the salt from it.

Oil is an organic molecule that is non-polar

Salt is polar ionic compound

Salt will not dissolve in the oil.

  • Take the mixture.
  • Add water to it.
  • Water and oil are immiscible
  • Shake the new heterogeneous mixture vigorously.
  • leave to settle.
  • Oil will come on top of the water.
  • You can skim off the oil layer on top.
  • Then heat the water and salt solution.
  • This leaves the oil behind.
