The liquid that is placed in an evacuated
sealed flask will reach in dynamic equilibrium if the amount of liquid inside
the flask will stop converting into vapor. This process is to balanced the
amount of substance of both phases inside the flask.
<span>All collisions between atoms or molecules are perfectly elastic and are not the result of any attractive forces is the best answer in my opinion since ideal gas particles have elastic collisions and do not interact with each other.</span>
Explanation:
Helium exists in three different forms due to the phenomenon of isotopy. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their nuclei.
- The atoms of these elements are called isotopes.
- This is why Helium can exist in three different forms.
- Isotopes have the same electronic configuration but with the same chemical properties.

Alkane have the empirical formula of c3h8
Answer:
pH = 5.76
Explanation:
We can solve this problem by using<em> Henderson-Hasselbach's equation</em>:
pH = pKa + log
We are already know all the required information, thus we<u> input the data given by the problem</u>:
pH = 4.76 + log(20/2)
And finally <u>calculate the pH</u>:
pH = 5.76
The pH of that acetic acid solution is 5.76.
