Answer:
pH ( potential Hydrogen ) is a negative logarithm of molar concentration of hydrogen ions.
![pH = - log[H {}^{ + } ]](https://tex.z-dn.net/?f=pH%20%3D%20%20-%20%20log%5BH%20%7B%7D%5E%7B%20%2B%20%7D%20%5D)
therefore:

Going to different website and watching different science videos on the unit you are on
The force acting between two charged particles A and B is 5.2 x 105 newtons. Charges A and B are 2.4 x 102 meters apart. If the charge on particle A is 7.2 x 108 coulombs, what is the charge of particle B? (k 7 9.0 x 109 newton meters?/coulomb)
Answer:
No, the metal is not pure gold because density is equal to mass divided by volume and in this case we end up with about 15.3, making this metal less dense than gold.
Explanation:
The given question is incomplete. The complete question is:
The pH of a 0.98 M solution of propanoic acid is measured to be 2.43. Calculate the acid dissociation constant of propanoic acid. Round your answer to two significant digits.
Answer: The acid dissociation constant of propanoic acid is 
Explanation:

cM 0 0

So dissociation constant will be:

Give c= 0.98 M and pH = 2.43



The acid dissociation constant of propanoic acid is
