Actually, I strongly believe it is a switch.
Answer: The pressure of the He is 2.97 atm
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given :
=total pressure of gases = 6.50 atm
= partial pressure of Nitrogen = 1.23 atm
= partial pressure of oxygen = 2.3 atm
= partial pressure of Helium = ?
putting in the values we get:
The pressure of the He is 2.97 atm
The valence electron ring is full. The ring has 8 electrons already.
There are 22 bonding parts
Valence shell it contains the valence electrons e.g. the outermost electro
