What else can I help you with?
If a tube of hydrogen gas is placed above a test tube of air why would the tube of air give a positive test for hydrogen after a few seconds?
the hydrogen would likely begin bonding with the oxygen in the test tube, and become heavier. As this product falls out, it would pull more hydrogen to the end of the tube, putting more hydrogen in contact with the oxygen, much the same way as an oil lamp pulls the oil fumes from the base of the lamp to the flame.
