For a weak acid such as the side chain ε-amino group of a lysine residue in a protein, if the pKa of that specific residue's ε-a

mino group is exactly 10.0, in an environment in which the pH = 9.0, what would be the ratio of base to acid?

Neko [114]2 years ago
6 0

Answer:

0.1

Explanation:

Using Henderson-Hasselbalch equation

pH = pKa + log ( base / acid )

pH= 9.0 , pKa = 10.0

9.0 = 10 + log ( base / acid )

9 - 10 = log ( base / acid )

10⁻¹ = ( base / acid )

( base / acid ) = 0.1

Would a false positive from the reaction between the inoculating loop and hydrogen peroxide
Svetradugi [14.3K]
The false positive from the response of hydrogen peroxide and the immunizing circle would be created by poor specificity. The recipe for specificity is TN/TN+FP. False-positive outcomes can be ascribed to meddling substances in nature where the strips are put away or utilized, for example, hydrogen peroxide (H2O2) or fade (hypochlorite).

1 mole of Cl2 will produce how many atoms of KCl?
olchik [2.2K]

Answer:

1.1 mole

Explanation:

The mass of potassium chloride is 3.8 g . Look at the mole ratio you have between potassium chlorate and potassium chloride; what you will see is that every 2 moles of potassium chlorate will produce 2 moles of potassium chloride, i.e. you have a 1:1 mole ratio between the two compounds
