Answer: 0.3
Explanation:
We know that
Ka = [H+] * [A-] / [HA]
And the acid is 15 % dissociated means that
[A-] / [HA] *100 = 15%
So
[A-] / [HA] = 0.15
Then we know that [H+] = [A-] = 2 molar
Replacing we have
Ka = 2 molar * 0.15 = 0.3
Iodine dissolves easily in chloroform and hexane but does not dissolve in water. When polar and non-polar are mixed, water finds other water and forms spherical bubbles. When mixed with hexane, the iodine molecules experience London dispersion forces. There is no induced polarity in the iodine molecules and they exhibit their typical violet color in the solution. (Note: The color may be pink if the iodine concentration is low.) Hope this helps!!
Answer:
Your question is missing some information.
But in most of the systems, potential energy and kinetic energy are inversely proportional
Hi Alex,
I think your answer is (<span>a seafloor that was geologically active with earthquakes, volcanoes, and mountain chains) Good luck!
