The question is not straight forward, and the reason for that is that any material / compound / element that will burn in oxygen, will decay at a particular rate in a fire. So for example, highly combustible materials such as gasoline, or hydrogen, will combust rapidly in a relatively low percentage of oxygen. In the case of hydrogen, H2, the percentage of oxygen required to use up all the H2 present will be 50%, since the compound produced is H2O. If there is this much oxygen present, the result will be quite explosive. For a controlled fire or reaction, you would control the oxygen input, and / or the hydrogen input. Think of an engine in a car, only the fuel in the cylinder gets used / burned, not the entire gas tank!

∙ 10y agoDepends on what, and how much of it that's burning.
The chemical reactions that happens in a fire are fairly well known, so if you know what, and how much that is getting burnt it's possible to calculate how much oxygen that particular fire will use up.

∙ 9y agoIf oxygen is the oxidizing element of the atmosphere used to continue fueling the flames, the air only needs 16% minimum. Air contains 21% oxygen. However, other sources of combustion are available, such as fluorine burning water, or hydrogen burning chlorine.

∙ 12y agoThis amount depends on the amount of carbon (and other combustibles compounds) in the burning materials; fire is an oxidation reaction.

∙ 13y agoThat depends on the 'fuel' that is burnt: wood, petrol, alcohol, hydrogen gas ALL have there own 'fire-sustaining' oxygen concentrations.

Does fire need carbon to burn?
No. Only oxygen is sufficient for something to combust.
What is needed for fire to burn?
In order for fire to burn, there is someting called the fire tetrahedron. The things needed for fire to burn are as listed: Heat, Oxygen, Fuel(of any sort), and a Chmeical Reaction with all of the above. I learned this from the multiple firefighting classes i have taken.
What is need to burn fuel?
To burn a fuel, the other two things needed are oxygen and heat. Heat could come from a flame to start the fire (once the fire is started it continues to produce enough heat unless it runs out of fuel or oxygen, or is put out), or it could come from a spark.
What happends to a burning candle if there is no oxygen?
It will simply go out as fire needs to burn oxygen, too. You can see this. Empty and clean an aluminum soda can. Place a burning candle deep in a jar. Pour a teaspoon of hydrogen peroxide in the soda can. Cover and shake upright. Leave the liquid in the can while you slowly pour the carbon dioxide gas into the jar and it puts the candle out by pushing all the oxygen up and out.
What do you need to start a fire?
You need oxygen, heat, and fuel.
Can a fire burn in a room with no oxygen?
No it can't. You need oxygen to burn for it to work.
What does a fire need to burn well?
oxygen
Does fire need air to breathe?
Fire needs oxygen to burn.
Does fire need oxygen in order to burn?
yes it does
Does a fire have oxygen?
Yes, most fires need oxygen to burn (combustion is a rapid form of oxidation). If there is no continuous supply of oxygen, a fire will go out.
Does putting out fire need oxygen?
No. Adding oxygen to a fire will make it burn faster and hotter. In fact, one of the ways of putting out a fire is to cut off the supply of oxygen.
What is needed for something to burn?
Fire need a fuel, so wood or leaves and of course it needs Oxygen (O2)! That's that. A fire needs three things, feul, oxygen and heat, remove any one and the fire will die.
Does fire need carbon to burn?
No. Only oxygen is sufficient for something to combust.
Why does covering a burning object with a blanket help to extinguish a fire?
throwing a blanket over a small contained fire stops oxygen to the fire .to stop a fire you need to take out one of the three elements that are needed for a fire to burn witch are heat /oxygen/fuel
Does oxygen make something burn?
No it doesn't make something burn. But if something is already burning, it supports the burning. In the fire triangle, which is what makes a fire, it says that you need fuel, oxygen, and something else, that I tend to forget. So, technically, oxygen does make something burn, because you need that oxygen to help it and if you don't have that then it won't burn. So, I say yes, it does.
What in co2 puts out an electricity fire?
Fires need oxygen to burn. Without it, the fire goes out. Using CO2 displaces oxygen in the environment.
Why do rockets need to carry a supply of oxygen?
Rockets need to carry a steady supply of oxygen so that the fire that takes them off of the ground can burn. You must remember that to have fire you must have oxygen.
