A gas mixture contains oxygen, nitrogen, and carbon dioxide. It has a pressure of 250 mmHg. If the pressure of oxygen is 50 mmHg and the pressure of nitrogen is 175 mmHg then what is the pressure for carbon dioxide?

Answers

Answer:

[tex]P_{CO_2}=25mmHg[/tex]

Explanation:

Hello there!

In this case, according to the Dalton's law, which explains that the total pressure of a gaseous system equals the sum of the partial pressures of the gases composing, for the gaseous mixture composed by oxygen, nitrogen and carbon dioxide it would be possible to write:

[tex]P_{tot}=P_{N_2}+P_{O_2}+P_{CO_2}[/tex]

Now, given the pressure of the system and those of oxygen and nitrogen, we calculate that of carbon dioxide as shown below:

[tex]P_{CO_2}=P_{tot}-P_{N_2}-P_{O_2}\\\\P_{CO_2}=250mmHg-50mmHg-175mmHg\\\\P_{CO_2}=25mmHg[/tex]

What causes a substance to be hydrophobic?

Answers

The hydrophobic effect is caused by nonpolar molecules clumping together. Large macromolecules can have hydrophobic sections, which will fold the molecule so they can be close to each other, away from water. Many amino acids in proteins are hydrophobic, helping the proteins obtain their complicated shapes. The hydrophobic effect extends to organisms, as many hydrophobic molecules on the surface of an organisms help them regulate the amount of water and nutrients in their systems.

The wave which is having higher frequency is associated with higher energy. In the given wave, the part B is labelling the lowest energy sound.

What are sound waves ?

Sound waves are longitudinal mechanical waves passing through a medium. In a longitudinal wave the oscillation of particles is in a direction along the wave propagation.

A sound wave is composed of rarefactions and compressions. The area where, the particles have some separation with lower  pressure is called rarefactions.

The area of high pressure where, the oscillating particles are closely packed is called compression of the wave. As the frequency of the wave increases, its energy increases, Therefore, the less frequency part B represent lowest energy sound.

what is the hydrogen ion concentration in a 0.10M solution of KOH?​

Answers

KOH is a strong base, so [OH-] = 0.10 M = 1.0 x 10^-1 M

[H+][OH-] = Kw

Kw = 1.0 x 10^-14

[H+] = 1.0 x 10^-14 / 1.0 x 10^-1 = 1.0 x 10^-13 M

Calculate the Keq of the reaction CH4 + O2 ⇌ CO2 + 2H2O, given the following concentrations at equilibrium:
[CH4] = 0.37M [O2] = 0.25M [CO2] = 0.86M [H2O] = 0.44M

If the He H e injected into the abdomen produces a pressure of 22 mmHg m m H g and a volume of 2.7 L L at 31 ∘C ∘ C , how many grams of He H e were used?

Answers

Answer:

1280.27 g

Explanation:

Pressure = 22 mmHg / 760 = 0.0289 atm (Converting to atm by dividing by 760)

Volume = 2.7 L

Temperature = 31 ∘C + 273 = 304 K

Mass = ?

Using the ideal gas equation;

PV = nRT

n = RT / PV = 0.0821 * 304 / ( 0.0289 * 2.7)

n = 319.86 mol

Mass = Number of moles * Molar mass

Mass = 319.86  * 4.002602

Mass = 1280.27 g

You are testing a solution for pH and find it to be 8.31 on the pH scale. Is this solution acidic, basic or neutral. Explain.

Answers

it's neutral

Explanation:

on the ph scale 7-8 is in the middle and everything after 8 is acidic and everything under 7 is basic. (you can look up a picture of a ph scale you will see what I mean)

This solution is neutral .

One useful method for calculating how acidic something is on a quantitative level is to utilize the pH scale. A solution is considered acidic if its pH value is less than 7. The solution is neutral if the pH is 7, and basic if the pH is higher than 7.

What distinguishes neutral, acidic, and basic solutions?Neutral solutions are those with a pH of 7. The solution is acidic if the pH value is less than 7. The solution is basic when the pH value exceeds 7. These values increase on a negative logarithmic scale and represent the concentration of hydrogen ions in the solution.How does pH scale work?pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
