Recall that the value of Kw for the autoionization of water varies with temperature. At the temperature of your body (37°C), Kw
kvasek [131]

Answer:

pH =6.70

Explanation:

When Kw = 1x10^-14

[H3O+] = [OH-] --> 1x10-7

Kw =3.98x^10-14

3.98x^10-14 = [H3O+] . [OH-]

√ (3.98x^10-14) =  [H3O+] = [OH-]

[H3O+] = 1.99×10^-7

- log [H3O+] = pH ---> -log 1.99x10^-7 = 6.70

Alex's teacher showed him a model of gas particles in a sealed container. How should Alex change the model to show the particles
Inessa05 [86]

Answer:

  • Increased volume of particles in the container
  • greater vibration of particles

Explanation:

At higher temperature, the particles of the gas would be more active and vibrate more, or even have greater collisions. Alex can indicate this in the altered model to depict higher temperature.

Consequently, Charles law gives meaning to why there would be an increased volume of gas in the stable pressurized container, if the temperature were to be increased.

I hope this explanation was clear and concise?
