Answer:
The distance the plane flies.
Explanation:
This is the dependent (outcome) variable because it is changing depending on the number of paper clips that are added to the plane.
Where are the answers that apply .. hopes this help :)
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>
There is no definite answer but scientists believe the of you go closer towards the earth's core it can get extremely hot.
Answer:
pH = 14
Explanation:
pOH = -log[OH-] = -log1,0 = 0
pH + pOH = 14
pH = 14 - pOH = 14 - 0 = 14
