You need to state temperature and pressure of the gases I think, from this you can find the number of moles of both.
The equation is 2H2 + O2 => 2H2O
calculate the moles burned (for every 2 moles h2, 1 mole of O2 will burn.

Which gas in the air is needed for fuels to burn?
oxygen is needed for fuel to burn
Why is oxygen needed to make something burn?
If you want to be really specific, you can have a flame using other things. For example, a jet of hydrogen will burn in an atmosphere of chlorine. You get hydrogen chloride then. But if you burn the hydrogen in oxygen you get water. These examples demonstrate that burning is a chemical reaction and a great many things will combine with oxygen and in many cases small particles of white/red hot material are given off. This is a flame.
How many liters of oxygen are needed to burn 10 liters of carbon monoxide?
There are two oxygen atoms in each molecule (hence the prefix di). Ten CO2 molecules would require twenty oxygen atoms
What elements to you get when you burn hydrogen with oxygen?
Hydrogen and oxygen are already elements. You don't get elements as a product. You get water, which is a compound.
When you burn hydrogen and oxygen what molecule is created?
aded
Is H2O what you get if you mix hydrogen and oxygen?
No. Simply mixing hydrogen and oxygen will not get you water. You must burn the mixture.
Can you get hydrogen back if you burn it?
Yes. When you burn hydrogen the product is water. If you pass an electric current through that water you can split it back into hydrogen and oxygen.
Why does something need oxygen to burn?
Technically hydrogen and helium do not need oxygen to burn, they burn by themselves, otherwise the object that needs burning must have oxygen as a supplimental fuel source.
What gas is needed to burn paper?
Oxygen.
What element is needed for a substance to burn?
oxygen
Which gas is needed for a candel to burn?
oxygen
Why is water formed when you mix hydrogen and oxygen gases?
Water is H2O. 2 hydrogen atoms and 1 oxygen atom. Water is not formed when you mix hydrogen and oxygen. An explosive mixture of hydrogen and oxygen is formed. When you burn hydrogen in oxygen, the resulting compound is water. When you boil water the result is steam, or water vapor. Boiling does NOT separate the hydrogen and oxygen. An electrical current is needed to separate the hydrogen and oxygen. CAUTION: Do NOT put salt in the water to speed up the electrolysis of water. It changes the products. instead of hydrogen and oxygen, you get hydrogen, chlorine (gas), and sodium hydroxide. The last two are very poisonous.
