Answer:
is dissociation constant and the value of 
is 4.98.
Explanation:
The pH of the solution = 2.95 M
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
![2.95=-\log[H^+]](https://tex.z-dn.net/?f=2.95%3D-%5Clog%5BH%5E%2B%5D)
![[H^+]=10^{-2.95}=0.001122 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-2.95%7D%3D0.001122%20M)

Concentration of unknown monoprotic acid = C = 0.1224 M
Initially
C 0 0
At equilibrium
(C-x) x x
The expression of a dissociation reaction can be written as;
![K_a=\frac{[A^-][H^+]}{[HA]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BA%5E-%5D%5BH%5E%2B%5D%7D%7B%5BHA%5D%7D)
![[H^+]=x =0.001122 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3Dx%20%3D0.001122%20M)
( from [1])
The value of :
![pK_a=-\log[K_a]](https://tex.z-dn.net/?f=pK_a%3D-%5Clog%5BK_a%5D)
![=-\log[1.038\times 10^{-5}]=4.98](https://tex.z-dn.net/?f=%3D-%5Clog%5B1.038%5Ctimes%2010%5E%7B-5%7D%5D%3D4.98)
is dissociation constant and the value of is 4.98.
200,000 kilometers is the total distance traveled.
50,000 x 4 = 200,000
please mark brainliest.
The cerebrum is part of the brain that controls the functions of the voluntary activity in the body. If an organism is smaller than another organism, for this case a frog and a rabbit. It means that the frog and the processes inside that body are less complex. Thus, the cerebrum do not need to be bigger than the cerebrum of a bigger organism.
Answer The principal type of fermentation is the action of the yeast on fermentable sugars to produce carbon dioxide (CO2), ethanol, and some aromatic compounds. The organoleptic characteristics of bread, namely, the texture, flavor, and aroma, depending on the conditions of the dough fermentation.
