Explanation:
Let's consider the acid dissociation of barbituric acid.
HC₄H₃N₂O₃(aq) ⇄ C₄H₃N₂O₃⁻(aq) + H⁺(aq)
The pH is 1.93. We can find the concentration of H⁺.
pH = -log [H⁺]
[H⁺] = antilog -pH = antilog -1.93 = 0.0117 M
The concentration of the acid (Ca) is 1.4 M. We can fidn the acid dissociation constant (Ka) using the following expression.
[H⁺] = √(Ca × Ka)
[H⁺]² = Ca × Ka
Ka = [H⁺]² / Ca
Ka = (0.0117)² / 1.4
Ka = 9.8 × 10⁻⁵
Answer:
Fatty acids are comprised of hydrocarbon chains terminating with carboxylic acid groups. Fatty acids and their associated derivatives are the primary components of lipids. The length and degree of saturation of the hydrocarbon chain is highly variable between each fatty acid, and dictates the associated physical properties (e.g., melting point and fluidity). Moreover, fatty acids are responsible for the hydrophobic properties (insoluble in water) exhibited by lipids.
Function of Fatty Acids
Explanation:
Explanation:
The given equation is as follows.
Reactants are the species present on the left hand side of a chemical equation.
Products are the species present on the right hand side of a chemical equation.
Whereas coefficients are the number present in front of formulas.
Therefore, in the given reaction equation, matched terms are as follows.
- Reactant is
- Product is AB.
- Coefficient is 2.
2,10,4 are valence electrons
