No hydrogen will not burn in the absence of air unless another oxidizer is present.
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.
i don't know but i do know that my mig welder needs pressured air and hydrogen to burn the metal
Hydrogen introduced into air forms a highly flammable mixture, but in order to ignite it you need to apply enough heat.
Hydrogen is a colorless gas that burns with oxygen. If substances will burn in air, those same substance will burn better in oxygen.
Different sources give different numbers. A hydrogen flame in air burns at"2045 °C""2,400 K" = 3860 °C"2483 K" = 2127 °CA hydrogen flame in a pure oxygen environment can burn hotter:"2660 °C""3,080 K" = 2800 °C"3473 K" = 3200 °CHydrogen energized by an electrical arc until it separates into lone atoms, and then burned (an "atomic hydrogen torch"), can produce even hotter flames, at 4000 °C to 5000 °C.
It will not burn.
helium does not burn, hydrogen will burn in air
Hydrogen burn in air releasing a typical sound.

With traces of P2H4 present, PH3 is spontaneously flammable in air
It burns faster in pure oxygen.

NO. Hydrogen gas is non-toxic. However, it can displace oxygen (and if hot enough burn in it) and thus can be an asphynxant in large quantities. But hydrogen by it self is not toxic at all.
This is a badly worded question, I believe "burning" requires the oxygen in air. Substances such as Phosphorus react with air to burn, and may continue this reaction when submerged. But I do not believe this is what you mean
It turns into pure water that can be drunk.

the absence of air is "vacuum"
