You can mix it but it will not stay mixed. Like oil mixed with water, hydrogen is much, much lighter then the rest of the components of air and it will therefore separate out.
because hydrogen is collected by the upward displacement of air although it is 14.5 times lighter than air B)
Hydrogen chloride. If you mix it with water, you get hydrochloric acid.
this happens because hydrogen is lighter than air
no it is a gas and as a gas it cant be seen
hydrogen gas is blue although you cant see it until it is mixed with an acid
i don't know but i do know that my mig welder needs pressured air and hydrogen to burn the metal

No one obtains hydrogen by separating it from air. There's not enough hydrogen present in air for that to be a viable source. However, it's possible to mix oxygen and hydrogen, yes. It forms a flammable (and explosive, if you get the proportions just right) mixture of gases.
They breathe air, which contains oxygen. They do not breathe hydrogen, as it is a bad idea to mix hydrogen and oxygen unless you intend to create anexplosion.
Helium is completely inert, it is the most inert of all elements, and so it will not react in any way with hydrogen (or with any other element). So, if you mix hydrogen and helium, nothing happens. You have a mixture of hydrogen and helium. It's a lot lighter than air, you can make balloons that will float. Of course, you can do that with pure hydrogen or with pure helium, as well.
Because if released in the air(oxygen) the mixture becomes explosive. Remember in the lab. to test for hydrogen is the 'pop' test. This is hydrogen igniting with oxygen.
Air isn't considered an element because it is made up of several different elements, such as Oxygen, Nitrogen, Hydrogen, and Carbon.
You get a mixture of hydrogen and xenon.
Hydrogen is already a element in the air. So in other words, nothing will happen. +++ That is Not Correct on both counts. Think about it: hydrogen is extremely flammable. Hydrogen is an element, yes, but not a component of the atmosphere, except perhaps in vanishingly tiny quantities. Besides, the question posits a deliberate mixing. Hydrogen burns in air, i.e. combines exothermically with oxygen that IS in the atmosphere, producing water.
how saparate hydrogen from air
No. Simply mixing hydrogen and oxygen will not get you water. You must burn the mixture.
mix water with hydrogen duuuuh!
