Answer:
The dissociation constant of phenol from given information is 
.
Explanation:
The measured pH of the solution = 5.153
Initially c
At eq'm c-x x x
The expression of dissociation constant is given as:
![K_a=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OOH]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BC_6H_5O%5E-%5D%5BH%5E%2B%5D%7D%7B%5BC_6H_5OOH%5D%7D)
Concentration of phenoxide ions and hydrogen ions are equal to x.
![pH=-\log[x]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5Bx%5D)
![5.153=-\log[x]](https://tex.z-dn.net/?f=5.153%3D-%5Clog%5Bx%5D)
The dissociation constant of phenol from given information is .

Hope this helps:)
Explanation:
Your exercise: Step by step:
1*225/88*r*a=1*(0/-1)*e+1*(__/88)*r*a | If the numerator equals zero, the fraction will be zero
1*225/88*a*r=1*0*e+1*(__/88)*r*a | Multiply 0 by e. Any number multiplied by 0 is 0.
1*225/88*a*r=0+1*__/88*r*a | Multiply __/88 by a. You can multiply a fraction by a number by multiplying the number and the numerator.
1*225/88*a*r=0+1*__*a*a*r | Multiply (__*a)/88 by r. You can multiply a fraction by a number by multiplying the number and the numerator.
1*225/88*a*r=0+1*(__*a*r)/88 | · 88
1*225*a*r=88*(__*a*r)/88 | Multiply 88 by (__*a*r)/88. You can multiply a fraction by a number by multiplying the number and the numerator.
225*a*r=88*(__*a*r)/88 | Cancel (__*88*a*r)/88 with 11*2^3
225*a*r=(__*a*r)/1 | Numerator 1 of (__*a*r)/1 can be omitted .
225*a*r=1*__*a*r | : 225
1*a*r=1*__*0.004*a*r | Divide both sides by a .
1*r=1*(__*0.004*a*r)/a
By definition, motion is the change of position over time. The obvious answer would be
<span>
A change in position over a certain amount of time.
If we investigate the choices, the first one talks about acceleration. That is delta velocity over delta time. The third choice is simply distance. And the fourth one is just a point in space used as a reference.
I hope I was able to explain it clearly :)</span>
