Have a nice day
If 1mol ------- is ----------- 6,02×10²³
so x ------- is ----------- 1,39×10²⁴
The noble gases are relatively unreactive because they have a stable octet of valence electrons.
Thus, they do not tend to undergo reactions in which they will gain or lose valence electrons,
However, <em>only He, Ne, and Ar are inert</em>. Kr and Xe combine with other highly reactive elements to form stable compounds.
Please dont harm yourself. whatever youre going through, you will get through it. i wish i could give you hug. you deserve so much happiness. but please dont hurt yourself.
Answer:
Pressure of the trapped gas and the pressure on the outside on the piston are the same.
Explanation:
When the piston is at rest, then it exist a mechanical equilibrium, that is to say, that pressure of the trapped gas is equal to the pressure on the outside of the piston.
