Two gas jars are connected to each other, but they are separated by a closed valve. one gas jar contains oxygen, and the other contains hydrogen. what will happen when the valve is opened?

oxygen and hydrogen molecules will mix because of random movement of their molecules.

oxygen and hydrogen molecules will remain in separate jars because of different partial pressures.

oxygen and hydrogen molecules will remain in separate jars because of different rates of expansion.

oxygen and hydrogen molecules will mix because the molecules have a much lower volume than the volume of the jars.

i think its a or d

It is most likely A since gas particles do not have a fixed volume.

A) Oxygen and hydrogen molecules will mix because of random movement of their molecules.

I took the test and A Is correct

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

um i think it might be a car?
