Hello itsbabyrene99!
The answer to your question is 800 cm^3.
.
V = s^3
V = (20cm)^3
V = 800 cm^3

Diffusion is the net movement from an area of higher concentration to an area of lower concentration. The mechanism by which this happens is the random molecular motion: the right answer is " <span>Diffusion is
the movement of molecules from an area of lower concentration to one of
higher concentration by random molecular motion"</span>
Answer:
a. True
Explanation:
Yes, the titration curve can determine or can reveal the pKa value of a weak acid.
Titration is a scientific method to estimate the dissolved substance concentration, known as the titrand, in a known volume when it reacts with another chemical substance of known volume as well as concentration. The other substance is known as Titrant.
When a weak acid like acetic acid is titrated to a very strong base such as NaOH, the titration curve is obtained and the pH value is noted. But the titration curve of any weak acid shows a characteristic shape. At the end of titration, the acetic acid will convert into acetate ions.
pKa is the negative logarithm of the Ka of the acid. pKa is the pH of the acid where the concentration of the weak acid as well as the conjugate base is in equimolar concentration.
Answer:
Your question is missing some information.
But in most of the systems, potential energy and kinetic energy are inversely proportional
