C) medium.
The medium of a wave is any substance that carries the wave, or through which the wave travels.Ocean waves are carried by water, sound waves are carried by air, and. the seismic waves of an earthquake are carried by rock and soil.

Answer:</h3>
The gas obeys the Boyle's law
<h3>
Explanation:</h3>
- According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at constant absolute temperature.
- That is;

- Therefore,
, where k is a constant - At varying volume and pressures while keeping absolute temperature constant; k = P1V1 =P2V2
In this case, we are given;
Initial Volume of 13.0 L at initial pressure of 1.0 atm
New volume of 6.5 L at new pressure of 2.0 atm
But, K = PV
Therefore,
k1 = P1V1
= 1.0 atm × 13.0 L
= 13 atm.L
k2 = P2V2
= 2.0 atm × 6.5 L
= 13 atm.L
Thus, k1=k2
Thus, the gas obeys the Boyle's law
Answer:

Explanation:
<u>Answer:</u> The moles of hydrochloric acid is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

Or,

We are given:
Molarity of solution = 0.5173 M
Volume of solution = 
Putting values in above equation, we get:

Hence, the moles of hydrochloric acid is
