Fatty acids are composed of hydrocarbon chains and a carboxyl group.
<h3>What are Fatty acids ?</h3>
Fatty acids are the building blocks of the fat in our bodies and in the food we eat.
During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood.
Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.
Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end.
It is that carboxyl group that makes it an acid (carboxylic acid).

Answer:
Magnitude of work done = 24.28 J
Explanation:
No. of moles = Reacting mass/ Molar mass
Reacting mass of Na = 0.45 g
Molar mass of sodium = 23g/mol
∴ No. of moles of sodium = 0.45/23 = 0.0196 mole
If 2 moles of Na react with water at 25°C and 1 atm, 24.5 L of H₂ was formed.
∴ when 0.0196 mole of Na react with water under the same conditions, (24.5×0.0196)/2 L of H₂ will be formed.
⇒ (24.5×0.0196)/2 L = 0.24 L
0.24 L × 1 atm = 0.24 L . atm
Since 1 L · atm = 101.3 J
∴ 0.24 L . atm = (0.24 L . atm ×101.3)/1 = 24.28 J
Magnitude of work done = 24.28 J
