a) oxygen does not burn
b) oxygen combines with the fuel - it is NOT a catalyst.
c) a fire does acellerate when oxygen is added.
Fire is a chemical reaction between oxygen and a flammable substance. In this reaction the oxygen and the fuel are consumed to form new substances such as water vapor and carbon dioxide.
Set up a fire in the same box as the gas and see if the fire burns well. If it burns well, it is oxygen.
fuel,oxygen,heat
Just try lighting up a match, if it burns its a proof that oxygen is present...! But, do remember lighting up a match will start using the present oxygen, so if you think you'll have a limited amount of it available...be wise to put off the flame ASAP.
a backdraft occurs during a fire when intense heat is bottled up inside of a room and when oxygen is introduced via a door opening or a window breaking the fire flashes over.
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!

yes, it burns oxygen at a constant rate, that rate is unknown to me
Well a fire normally needs Gas Air and Oxygen so it burns when you turn the gas on the fire will automatically shows up because you are completing the triangle to make fire which is GAS+AIR+OXYGEN=fire
burns stuff up
No. Fire is a chemical reaction between oxygen and a flammable material. Adding extra oxygen speeds up the reaction, making the fire burn even hotter and making it easier for the fire to spread.
As it burns it uses up oxygen.
First of all the fire that you see is just the light emitted by a chemical reaction called oxidation. This reaction consumes energy, in the form of oxygen and a flammable material such as wood. If either one runs out the fire dies. So in short, fire requires a constant supply of energy and that runs out so fire 'burns up'.
it's a candle from the wax it makes the fire heat up
Part of air is made up of oxygen without which fire can't happen. Air can feed a fire; it contains oxygen.
Among other things:* You'll no longer have a match stick.* The wood of the match stick will convert to smoke; among other things, CO2 will be produced.* In the process, some oxygen will be used up.
to reach the oxygen for fuel
A house burns up (heat rises) but they say it burns down. A figure of speech.
