Answer:
The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the decibel (dB) Intensity of sound results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound.
Explanation:
The percent composition of Cesium and Fluorine in CsF are 87.493 % and 12.507 % respectively.
<h3>What is a percentage composition?</h3>
Percent composition is very simple. Percent composition tells you by mass what percent of each element is present in a compound.
Molecular mass of Cs = 132.9054519
Molecular mass of F = 18.9984032
Molecular mass of CsF = 132.9054519 + 18.9984032 = 151.9038551
CsF: Percent composition by element:
Cesium (Cs) = = 87.493 %
Fluorine (F) = = 12.507 %
Hence, the percent composition of Cesium and Fluorine in CsF are 87.493 % and 12.507 % respectively.

During Georgia’s severe drought in 2007, the Centennial Park was under redevelopment.
Option B, They cannot be separated by using physical properties
I'll go over why the other three options are wrong.
Option A - Boiling water would break the Intermolecular Forces between molecules (Essentially, the force that keeps water molecules stuck together will break, not the force that holds the atoms together)
Option C- Water isn't a mixture (Assuming that it's distilled), and so filtering it would do absolutely nothing.
Option D - There aren't any metallic bonds in water, only polar covalent bonds.
Thus, the only answer left is Option B.
Let me know if you need me to explain anything I mentioned here.
