Answer:
Leucine, isoleucine and lysine are classified as <u>essential amino acids.</u>
Explanation:
Amino acids are the important biomolecules in which an alpha-carbon is attached to a side chain R, two functional groups and one hydrogen.
The two functional groups are: amine group (-NH₂) and carboxyl group (-COOH).
There are total <u>21 amino acids in a human body</u>.<em><u> They can be divided into two types: Essential amino acids and Nonessential amino acids</u></em>
Essential amino acids are the 9 amino acids that can not be produced by the human body and thus has to be taken through diet.
<u>Example: leucine, isoleucine, lysine.</u>
<u>Therefore, leucine, isoleucine and lysine are classified as essential amino acids.</u>
Answer:
Ammeter is a device to calculate electricity current and volt meter is a device to measure voltage.
The enthalpy change of the reaction is <u>-1347.8 kJ.</u>
<h3>What is the enthalpy change, ΔH, of the reaction?</h3>
The enthalpy change, ΔH, of the reaction is calculated from Hess's law of constant heat summation as follows:
Hess's law states that the enthalpy change of a reaction is the sum of the enthalpies of the intermediate reaction.
Given the reactions below and their enthalpy values;
1. X (s) + 12 O₂ (g)⟶ XO (s) ΔH₁ = −850.5 kJ
2. XCO₃ (s) ⟶ XO (s) + CO₂ (g) ΔH₂ = +497.3 kJ
The enthalpy change, ΔH, of the reaction whose equation is given below, will be:
X (s) + 12 O₂ (g) + CO₂ (g) ⟶ XCO₃ (s)
ΔH = ΔH₁ - ΔH₂
ΔH = − 850.5 kJ - (+497.3 kJ)
ΔH = -1347.8 kJ

Answer. One of the key components of the softgel capsule is the plasticizer used to make the shell elastic and pliable and to minimize brittleness and cracking. The plasticizer usually accounts for 20-30% of the wet gel formulation which can impact the quality of the finished product.
