False
Explanation:
Sound waves are longitudinal mechanical waves.
Mechanical waves are waves that requires a medium to propagate them.
- A transverse wave is a wave that is propagated perpendicularly to its source.
- An example is electromagnetic radiation.
- A longitudinal wave is a wave that is directed parallel to their source.
- Sound wave is a longitudinal wave.
- It has series of rarefaction and compression along its travel path.
- Rarefaction are areas of sparse particles.
- Compression are areas with dense particles.

Answer:
V₂ → 106.6 mL
Explanation:
We apply the Ideal Gases Law to solve the problem. For the two situations:
P . V = n . R . T
Moles are still the same so → P. V / R. T = n
As R is a constant, the formula to solve this is: P . V / T
P₁ . V₁ / T₁ = P₂ .V₂ / T₂ Let's replace data:
(1.20 atm . 73mL) / 112°C = (0.55 atm . V₂) / 75°C
((87.6 mL.atm) / 112°C) . 75°C = 0.55 atm . V₂
58.66 mL.atm = 0.55 atm . V₂
58.66 mL.atm / 0.55 atm = V₂ → 106.6 mL
The reasonable ground-state electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 4d8
