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.

When doing a titration what is the equivalency point of the neutralization reaction?
KengaRu [80]
The equivalency point is at the point of the titration where the amount of titrant added neutralize the solution. When it’s a strong acid strong base titration, the equivalence point will be 7. When it is a weak acid strong base, the equivalence point it more basic (the exact number depends on what acid and base you use). And when it is a strong acid weak base, the equivalence number is more acid (the exact number depends on what acid and base you use). Hope this helps!
