Hello!
The partial pressure of helium to keep the partial pressure of oxygen at 0,21 atm in a scuba-diver tank is
8,09 atmTo solve this question, we can use the
Dalton's Law, which states that the total pressure in a container with a mixture of gases is the sum of the partial pressures o each individual gas. For the case of this mixture the Dalton's Law is as follows:

In this equation, we need to clear for PHe, knowing that the PO₂ should be 0,21 atm, to find the required pressure of Helium:

Have a nice day!
The statement that best explains why xenon has a higher boiling point than neon is that xenon has more electrons than neon.
<h3>What are intermolecular forces?</h3>
The term intermolecular forces are the force that hold matter together in a particular state such as solid liquid or gas. The more the electrons present, the greater the polarizability and the greater dispersion forces at work.
Thus, the statement that best explains why xenon has a higher boiling point than neon is that xenon has more electrons than neon.
