At a depth of 100 ft in water, the external pressure is 4.0 atm. What is the solubility of N2 from air in blood at this pressure

Chemistry
1 answer:
Ira Lisetskai [31]3 years ago

Answer:

Solubility  = 2.142 x  10^{-4} M

Explanation:

Solution:

Note: This question is incomplete and lacks necessary data to solve this question. But I have found similar question on the internet and fetched the necessary data to solve:

Missing Data:

Number of Moles of N2 dissolved per litre of blood = 5.357 x 10^{-4} M

As we know that, the air is approximately. 78 mol % of N2

N2 = 0.78

Partial pressure of the N2 at 100 ft:

Partial Pressure = 0.78 x (4.0)

Partial Pressure = 3.12 atm

Now, this is 4 times the pressure of nitrogen at 1 atm air pressure.

SO,

According to the Henry's Law, we have:

Solubility = k x P_{g}

Here, k = 4 times

So,

Solubility = 4 x (5.357 x 10^{-4})

Solubility  = 2.142 x  10^{-4} M

A bond formed between Iron and Chlorine would<br> result in what type of bond?
katrin [286]

Answer:

Ionic bond

Explanation:

This type of chemical bond is called an ionic bond because the bond formed between two ions of opposite charge. The sodium cation (Na+) and the chlorine anion (Cl-) are attracted to one another to form sodium chloride, or table salt.

The gas in an aerosol can is at a pressure of 3.16 atm at 32.2°C. What would the gas pressure in the can be at 22.9°C?
olasank [31]

Answer:

The pressure of the gas would be 3.06 atm

Explanation:

Amonton's law states that the pressure is directly proportional to the absolute temperature of a gas under constant volume. The equation is:

P1 / T1 = P2 / T2

<em>Where P1 is the initial pressure = 3.16atm</em>

<em>T1 is initial absolute temperature = 273.15 + 32.2°C = 305.35K</em>

<em>P2 is our incognite</em>

<em>And T2 is = 273.15 + 22.9°C = 296.05K</em>

<em />

Replacing:

3.16atm / 305.35K = P2 / 296.05K

3.06 atm = P2

<h3>The pressure of the gas would be 3.06 atm</h3>

A chemist has synthesized two new dyes based on the molecular structure of plant-based dyes. The lowest energy absorption line f
Nimfa-mama [501]

Answer:

1. The dye that absorbs at 530 nm.

Explanation:

The dye will absorb light to promote the transition of an electron from the HOMO to the LUMO orbital.

The higher the gap, the higher the energy of transition. The energy can be calculated by E = hc/λ, in which h and c are constants and λ is the wavelength.

The equation shows that the higher the energy, the higher the gap and the lower the wavelength.

Therefore, the dye with absorption at 530 nm has the higher HOMO-LUMO gap.
