Two flasks are connected with stopcock. The first flask has a volume of 5 liters and contains nitrogen gas at a pressure of .75 atm. The second flask has a volume of 8L and contains oxygen gas at pressure of 1.25 atm. When the stopcock between the flasks is opened and the gases are free to mix what will the pressure be in the resulting mixture?

Bthats what im doing to and i figured it out it is b

Ithink it’s carbon dioxide

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
