At what temperature is the average speed of air particles the highest?

Chemistry
1 answer:
Law Incorporation [45]2 years ago
8 0

Answer:

Explanation:

Air is a mixture of roughly 80% nitrogen and 20% oxygen. The diatomic molecules of each type have a Maxwell-Boltzman distribution of velocities.

From the kinetic theory of gases the molecules kinetic energy will depend on the temperature.

Let’s use 300 K as room temperature : The nitrogen molecules have a root mean square velocity ( VRMS ) of 353 m/s. The average for all of the molecules is 347 m/s.

In general in gases of diatomic molecules the speed of sound is 68% of the molecular  VRMS .

What is the pH of a substance that has a hydrogen ion concentration of<br> 8.8x10^(-5) M? *
stealth61 [152]

Answer:

The pH of the substance is 4,06.

Explanation:

The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as:

pH = -log (H +)

pH= -log (8.8x10^-5)

<em>pH=4,06</em>
