Explanation:
Entropy is defined as the degree of randomness present in a substance. Therefore, more is the irregularity present in a compound more will be its molar entropy.
Hence, decreasing order to molar entropy in state of matter is as follows.
Gases > Liquids > Solids
- In the first pair, we are given
or 
. Since, molar entropy of liquids is less than the molar entropy of gases.
Hence, will have larger molar entropy as compared to .
- In the second pair, we are given Fe(s) or Ni(s). More is the molar mass of a compound more will its molar entropy. Molar mass of Fe is 55.84 g/mol and molar mass of Ni is 58.69 g/mol.
Hence, molar entropy of Ni(s) is more than the molar entropy of Fe(s).
- In the third pair, we are given
or 
. As both the given species are gaseous in nature. So, more is the molar mass of specie more will be its molar entropy.
Molar mass of is 30.07 g/mol and molar mass of is 28.05 g/mol. Therefore, molar entropy of is more than the molar entropy of .
- In the fourth pair, we are given
or 
. Molar mass of is 153.82 g/mol and molar mass of is 16.04 g/mol.
Therefore, molar entropy of is more than the molar entropy of .
- In the fifth pair, we are given HgO(s) or MgO(s). Molar mass of HgO is 216.59 g/mol and molar mass of MgO is 40.30 g/mol.
Hence, molar entropy of HgO(s) is more than the molar entropy of MgO.
- In the fifth pair, we are given NaCl(aq) or
. Molar mass of NaCl 58.44 g/mol and molar mass of is 95.21 g/mol.
Hence, the molar entropy of is more than the molar entropy of NaCl(aq).

Saliva is composed of a variety of electrolytes, including sodium, potassium, calcium, magnesium, bicarbonate, and phosphates. Also found in saliva are immunoglobulins, proteins, enzymes, mucins, and nitrogenous products, such as urea and ammonia.
<em>The frequency of the wave with a wavelength of is</em> <u>3.748 × 10 ⁶ /s</u>.
I attached the working and the answer to the question below. I hope I was able to help.
Please note that C = speed of light (2.998 × 10⁸ m/s), ν = frequency and λ= wavelength.
