Answer:bro u already have an answer why are you asking?
Explanation:
Answer:
of PABA is 0.000022
Explanation:

cM 0 0

So dissociation constant will be:

Give c= 0.055 M and
= ?

![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
![2.96=-log[H^+]](https://tex.z-dn.net/?f=2.96%3D-log%5BH%5E%2B%5D)
![[H^+]=1.09\times 10^{-3}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1.09%5Ctimes%2010%5E%7B-3%7D)
![[H^+]=c\times \alpha](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3Dc%5Ctimes%20%5Calpha)


Putting in the values we get:


Thus
of PABA is 0.000022
Mixing a base with an acid results in a chemical reaction called neutralization.<span> The result is a perfectly balanced solution of salt and water with a pH of 7 if the acid and base are balanced properly. Depending on the bases and acids used, it can be a dangerous experiment.</span>
2.5 km is the distance you can travel if a car gets 14 kilometers per liter and have 35 liters of gas.
Total distance traveled in 1 liter = 14 km
Total gas in the car = 35 liters
We have to find how much distance can be covered in in35 liters of gas.
Distance is the length of the path traveled between two points. It is the total movement of an object in a direction. It measures length.
Distance = 35/14
Or, distance = 2.5 km
Therefore, the total distance that can be covered by a car in 35 liters of gas is 2.5 km.
