The speed of sound at 20 oC in air is 343 m/s.

The speed of sound in helium at 20 oC is 927 m/s.

The speed of sound in natural gas  (methane) at 20 oC is 446 m/s.

Explanation:

  • The speed of sound depends upon the density and elasticity of gas.
  • The speed of sound is the distance which is traveled per unit time by a sound wave as it goes through an elastic medium.
  • The speed of sound in gas depends only on its temperature and composition.
  • Also the speed of sound refers to the speed of sound waves in air.
  • Air IS 343 m/s
  • Helium is 927 m/s.
  • Natural gas (methane) is 446 m/s.

Alexxx [7]
The normality that would be calculated will be to high because the change in volume will be greater than the actual change in volume. if the buret tip is not filled when reading the initial volume, the actual volume should be lesser with that reading. so if you will you the higher reading the change in volume or the volume you use in titration will be higher than the actual

Marat540 [252]

Answer:

Option C.

The Bohr effect describes the effect of pH on the affinity of hemoglobin for oxygen.

Explanation:

The hemoglobin is the oxygen carrying part of the blood. However, According to Christian Bohr, the binding affinity for oxygen by the hemoglobin in the blood is greatly affected by the acidity and content of carbon dioxide in the blood. As a matter of fact, they are inversely related. The more acidic the blood is, or the lower the pH of the blood, the lower the amount of oxygen that can become bonded with the hemoglobin in the blood.
