Answer:
The correct answer is the a=heat
Explanation:
Hello! Let's solve this!
Heat is responsible for regulating the temperature on Earth. When the temperature rises, the evaporation of water occurs, so it influences the water cycle. It also influences the climatic phenomena by increasing and lowering the temperature.
The correct answer is the a=heat
Answer:
Dissociated state is the predominant one
Explanation:
When a molecule with pKa of 4.52 is in an aqueous solution at pH = 4.0, follows the H-H equation, thus:
pH = pKa + log₁₀ [A⁻] / [HA]
<em>Where [A⁻] is the dissociated state and [HA] represents the protonated state</em>
Replacing:
4.0 = 5.2 + log₁₀ [A⁻] / [HA]
-1.2 = log₁₀ [A⁻] / [HA]
0.063 = [A⁻] / [HA]
[HA] = 16 [A⁻]
That means you have 16 times more [HA] than [A⁻] and the <em>dissociated state is the predominant one</em>
