Water is formed.
When hydrogen and oxygen gases are mixed, nothing happens, until a flame is put into the mixture. Whereupon there is a 'pop' and water is formed.
Here is the BALANCED reaction eq'n
2H2(g) + O(g) = 2H2O(l)
The 'pop' test is a classic lab. test for hydrogen .
If the gases are mixed in large quantities, then the 'pop' becomes an explosion.
NB
Fill two balloons , one with hydrogen and the other with helium. With a piece of string allow then to float in the air/room.
Put a lighted taper to the helium filled balloon. It will just pop and fall to the ground.
Put a lighted taper to the hydrogen filled balloon. It will pop with a flash of flame and a loud bang.
The question is rather poorly asked. It should be ' What other gas reacts with hydrogen to form water? ' The answer is oxygen. Hence is the balanced reaction eq'n. 2H2(g) + O2(g) = 2H2O(l) .
Oxygen
Hydrogen will be liberated.
The 'pop' test. To test for hydrogen , have a sample in an upturned boiling/test tube, hydrogen is lighter that air, put a lighted splint/taper to the mouth and it will 'pop' This is the classic hydrogen test.
when magnetic ribbon reacted with oxygen then it forms a new substance which is known as magnesium oxide[2mgo]
Hydrogen sulphide explodes when it is mixed with oxygen.

To determine the amount of oxygen that reacted when burning hydrogen, we can use the balanced chemical equation for the combustion of hydrogen: 2 H₂ + O₂ → 2 H₂O. From the equation, 2 moles of hydrogen produce 2 moles of water, meaning 1 mole of hydrogen produces 1 mole of water. Given that 24.2 grams of hydrogen (approximately 12.1 moles) produce 216 grams of water (approximately 12 moles), we can see that 12 moles of water would require 6 moles of oxygen, which corresponds to about 192 grams of oxygen. Thus, approximately 192 grams of oxygen reacted.
NO!!! Water is a COMPOUND, composed of the atoms of the elements hydrogen and oxygen. Two hydrogen atoms are electronically combined with one oxygen atom , hence forming the compound water (H2O). Structurally it is ' H-O-H '. NB It is NOT a mixture. In mixtures there is no electronic combination of atoms.
A chemical reaction between oxygen and hydrogen occur.
The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.
