Answer : The equilibrium concentration of 
in the solution is, 
Explanation :
The dissociation of acid reaction is:
Initial conc. c 0 0
At eqm. c-x x x
Given:
c = 
The expression of dissociation constant of acid is:
![K_a=\frac{[H_3O^+][C_6H_5COO^-]}{[C_6H_5COOH]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BH_3O%5E%2B%5D%5BC_6H_5COO%5E-%5D%7D%7B%5BC_6H_5COOH%5D%7D)
Now put all the given values in this expression, we get:
![6.3\times 10^{-5}=\frac{(x)\times (x)}{[(7.0\times 10^{-2})-x]}](https://tex.z-dn.net/?f=6.3%5Ctimes%2010%5E%7B-5%7D%3D%5Cfrac%7B%28x%29%5Ctimes%20%28x%29%7D%7B%5B%287.0%5Ctimes%2010%5E%7B-2%7D%29-x%5D%7D)
Thus, the equilibrium concentration of in the solution is,
Is there any answer choices before i get started on working out the problem
Answer : A.By
Step by Step Explanation
Answer:
Vertically Shrunk by a factor of 1/6
Explanation:
Parent Formula: f(x) = a(bx - c) + d
<em>a</em> - vertical shrink/stretch and x-reflections
<em>b</em> - horizontal shrink/stretch and y-reflections
<em>c</em> - horizontal movement left/right
<em>d</em> - vertical movement up/down
Since we are only modifying <em>a</em>, we are dealing with vertical shrink/stretch:
Since a < 1 (1/6 < 1), we are dealing with a vertical shrink of 1/6.
Since a > 0 (1/6 > 0), we do not have a reflection over the x-axis.
Answer:
The SI base unit for amount of substance is the mole. one mole is equal to one mole potassium bromide or 119.0023 grams
