The fire is fueled by oxygen in the air. There is no significant amount of hydrogen gas found in the atmosphere.
Does the question relate to a laboratory experiment involving hydrogen gas? Or is the question a general one? Oxygen is not a fuel, but it is required to support combustion, or rapid oxidation. Hydrogen is combustible and can be used as fuel. If you burn hydrogen, the fire is being fueled by the hydrogen, not the oxygen, but without O2, the hydrogen would not burn.
What else can I help you with?
Does fire need air to breathe?
No, fire does not "breathe" air like animals do. Air is necessary for fire to burn because it contains the oxygen that fuels the combustion process. Without oxygen, fires cannot start or continue burning.
What is a Source of oxygen for a fire?
the air
How many percent of oxygen need to support fire?
Around 16% of oxygen in the air is needed to support fire. This level is known as the minimum oxygen concentration required for combustion.
What gas in the air do you need to make fire?
Oxygen is the gas needed to make fire. It supports the combustion process by reacting with the fuel to produce heat and light.
Why do you need oxygen in space to make fire?
Fire needs oxygen no matter where it is. It is a chemical reaction between oxygen and some flammable substance. On Earth, the air is already 21% oxygen, so you only need to supply the fuel. In space there is no air and thus no oxygen, so you need to bring oxygen or some comparable oxidizer with you.
Why does fire need air?
Fire needs the oxygen in the air. Any other source of oxygen would also sustain fire.
Do you need air to have a fire?
Yes you need air. Or more correctly oxygen.
Does fire need air to breathe?
No, fire does not "breathe" air like animals do. Air is necessary for fire to burn because it contains the oxygen that fuels the combustion process. Without oxygen, fires cannot start or continue burning.

How you use nitrogen gas to control fire in mine?
A fire needs oxygen to burn. Air contains oxygen. So passing in nitrogen stops incoming air refuelling the fire. Have to be careful if there are trapped people who of course need to take in oxygen as they breathe.
What gas in the air do you need to make fire?
Oxygen is the gas needed to make fire. It supports the combustion process by reacting with the fuel to produce heat and light.
How does fire affect air?
Part of air is made up of oxygen without which fire can't happen. Air can feed a fire; it contains oxygen.
How can there be fire in space without oxygen?
Fire in space can occur without oxygen because it doesn't need air to burn. In space, fire can happen due to the presence of fuel and heat, even in the absence of oxygen.
Why do you need oxygen in space to make fire?
Fire needs oxygen no matter where it is. It is a chemical reaction between oxygen and some flammable substance. On Earth, the air is already 21% oxygen, so you only need to supply the fuel. In space there is no air and thus no oxygen, so you need to bring oxygen or some comparable oxidizer with you.
Does the fire take all oxygen out of air?
No, a fire consumes oxygen as it burns, but it doesn't take all the oxygen out of the air. There is still oxygen left for breathing and for sustaining life, even in the vicinity of a fire.
What is the source of oxygen for a fire?
the air
