Answer:
The stronger electrolyte is the HCl
Explanation:
Stronger electrolyte are the ones, that in water, completely dissociates.
HCl(aq) → H⁺(aq) + Cl⁻(aq)
HCl(aq) + H₂O(l) → H₃O⁺ (aq) + Cl⁻(aq)
Both are acids, they bring protons to medium but the hydrochloric completely dissociates.
HF (aq) + H₂O(l) ⇄ H₃O⁺(aq) + F⁻(aq) Ka
In the dissociation of weak electrolytes, they ionize but at the same time they bond again, so the reaction is always kept in equilibrium.
Humans are a living compound that contains hydrogen
Answer: The value of
for the weak acid is
.
Explanation:
First, we will calculate the molarity of HA as follows.
[HA] = 
= 
= 0.015
At equilibrium,

Initial: 0.015 0 0
Change: -x +x +x
Equilibm: 0.015 - x x x
It is given that, at equilibrium
[HA] = 0.015 - x = 0.013
- x = 0.013 - 0.015
= 0.002
Now, expression for
of this reaction is as follows.
![k_{a} = \frac{[A^{-}][H_{3}O^{+}]}{[HA]}](https://tex.z-dn.net/?f=k_%7Ba%7D%20%3D%20%5Cfrac%7B%5BA%5E%7B-%7D%5D%5BH_%7B3%7DO%5E%7B%2B%7D%5D%7D%7B%5BHA%5D%7D)
= ![\frac{x^{2}}{[HA]}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%7D%7B%5BHA%5D%7D)
= 
= 
Thus, we can conclude that the value of
for the weak acid is
.
There is 1,000 uL in one mL, so that would mean to move the decimal point 3 times to the left
Final answer: 19.0039 ML
The answer is so it didn't burn.
