No, three things are needed the ignite a fire, carbon (fuel), oxygen and heat.
If there is enough oxygen, the hydrogen will ignite and burn rapidly, possible leading to an explosion.
Because there are three things a fire needs to ignite- Fuel (wood petrol etc.), Heat (a match or lighter) and oxygen. Thats why fire cannot burn in space.
No. Oxygen itself is not flammable. Rather, it supports the combustion of flammable materials. Oxygen tanks do, however present a fire hazard. Normal air is 21% oxygen, while oxygen tanks carry 100% oxygen. A higher concentration of oxygen makes it easier to ignite flammable materials and allows a fire to burn hotter.
Nothing unless you have something to ignite the fuel. The oxygen makes a fire when combine with an ignition.* The fuel keeps a fire going, when the fuel discinigrates, then there is no more fire. *Usually an ignition is a spark.

Oxygen does not distribute fire. Fire is a chemical reaction between oxygen and some flammable substance. Fire cannot burn without oxygen, and the more oxygen there is, the hotter and faster a fire will burn. More oxygen also makes it easier for materials to ignite.
Not on its own. To have a fire you need three ingredients: fuel, oxygen, and heat. Fire is a chemical reaction between oxygen and some flammable fuel. The heat is needed to ignite and sustain the reaction. Our atmosphere is 21% oxygen, which makes fire possible here. Oxygen tanks, which contain pure oxygen, are a fire hazard because higher concentrations of oxygen make it easier for flammable materials to ignite and allow a fire to burn hotter and spread faster.
Fuel, Oxygen and a spark to ignite the flame. Use the Fire triangle.
Regular air in the environment is about 21% oxygen. A fire only needs about 16% oxygen to catch and burn. See http://www.bradford-co-fla.org/scvfd/fire_information.html
If there is enough oxygen, the hydrogen will ignite and burn rapidly, possible leading to an explosion.
When water is poured on fire it prevents the flow of oxygen to it and cools it down. The oxygen and hydrogen do not ignite because they are part of a compound and their properties change.
Please ignite the fire.
73 percent Edit: This answer can't possibly be accurate as air on earth is only 20% oxygen and is at it's highest level ever. Further more the amount of oxygen needed depends on what your trying to burn. Keep in mind that oxygen is NOT fuel for fire. Fire IS the even of oxygen combining with other materials. Fire is the effect of energy being released at the time of molecular fusion. Generally though, if at a high enough altitude where oxygen drops below 15% most things will not burn.
it can ignite a fire
No. Oxygen itself is not flammable, but it is necessary for fire. Fire is a chemical reaction between oxygen and a flammable substance. Fire is possible on Earth because ordinary air is 21% oxygen. Pure oxygen is considered a fire hazard because higher concentrations of oxygen will make it easier for a fire to ignite and will allow it to burn hotter and faster than normal.
Lightning or a brush fire can also ignite soft coal.Remove any one of the basic components, though, and the fire will either fail to ignite or will fizzle out by itself.Officials said a fire that had threatened to ignite the cars carrying the chemicals was still smoldering.The fire that he's been trying to ignite seems to be spreading.(Dictionary.com)
