Ranking order of speed of sound is; Steel >Water > Air.
Speed of sound in normal air is 340 m/s, in water the speed is 1,430 m/s and in steel the speed is 5920 m/s.
<h3>What is speed of sound?</h3>
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. The speed of sound in an ideal gas depends only on its temperature and composition. The speed of sound in mathematical notation is conventionally represented by 'c'. The speed of sound is variable and depends on the properties of the substance through which the wave is travelling.

#SPJ4
Two [hydrogen] atoms and one [oxygen] atom
I think the like term is 6 hope this is right
Answer:
C₃H₉N
Explanation:
The empirical formula of a compound is the fundamental and basic possible formula that shows the mole ratio of the atoms of each element in a molecule of the compound.
mole ratio of carbon = 60.94/12 = 5.078
mole ratio of hydrogen = 15.36/1 = 15.36
mole ratio of nitrogen = 23.70/14 = 1.693
Now; we will divide by the smallest value
So; carbon = 5.078/1.693 = 2.99 ≅ 3.0
hydrogen = 15.36/1.693 = 9.07 ≅ 9.0
nitrogen = 1.693/1.693 = 1 ≅ 1
Thus, the empirical formula is = C₃H₉N
