O2 because it has more electrons. Because of the higher number of electrons, it has higher dispersion forces (attractive forces). This means that more energy (heat) is required to unstick the molecules into a different state of matter.

Which member of of theawe pairs of substances would you expect to have a higher boiling point a o2 or n2 b so2 or CO2 c hf or hi?

a) O2 would have a higher boiling point than N2 since it experiences London dispersion forces in addition to its higher molecular weight. b) SO2 would have a higher boiling point than CO2 due to its ability to form stronger dipole-dipole interactions and London dispersion forces. c) HF would have a higher boiling point than HI due to hydrogen bonding, which is stronger than the dipole-dipole interactions present in HI.

Why doesn't air have a fixed boiling point?

The atoms in O2 move much too quickly to boil. ;D


What has the highest boiling point CH4 CO4 NaCl O2?

NaCl has the highest boiling point. It is an ionic compound with strong bonds between sodium and chlorine ions, requiring more energy to break these bonds and reach the boiling point compared to the other substances listed.


Which has a higher boiling point HI or HF?

HF is electronegative compared to O2. HF has delta plus and delta minus creating a dipole moment, it is a polar molecule therefore it has a higher boiling point. O2 which is symmetrical and non polar (looks like O=O) and therefore has no dipole moment.


Which is have highest boiling point Ne N2 O2 Cl2 SiH4?

The boiling point in degree Celsius are given below:Na: 883K: 774Si: 2355Ne: -246Silicon has the highest boiling point among the elements given.


Why N2 has lower boiling point then CO?

NO2 has a higher boiling point than CO2 because the nitrogen radii is larger than carbon. The bigger the atom the more intermolecular force that is created...this requires more energy to break causing a higher boiling point.


Is the boiling point hydrogen or oxygen colder?

It is simply the water that freexes. Water is not simply a mixture if hydrogen and oxygen. The two elements are bound together to form water molecules. So it must be treated as its own substance. The behavior of water cannot be explained using the behavior of elemental hydrogen or oxygen. Its properties are different from its constituent elements.


IS o2 an ideal gas at 35 ATM and 33.15K?

It isn't even a gas at that temperature let alone being ideal. The boiling point of O2 is 90 K and the melting point is 55K. So at 33 K it is a solid. At extremely low pressures this might change a bit, but you gave a huge pressure so not the case.

How would you separate helium and oxygen?

Helium and oxygen can be separated using cryogenic distillation. Since helium has a lower boiling point (-268.9°C) compared to oxygen (-183°C), they can be separated by cooling the mixture to a temperature between their respective boiling points and then distilling them off as separate components.
