At what temperature does hydrogen and oxygen burn?

1.4. 2 Practical Considerations

Fuel	Oxidizer	Temperature (K)
Heptane	Oxygen	3100
Hydrogen	Air	2400
Hydrogen	Oxygen	3080
Methane	Air	2210

At what temperature does hydrogen ignite?

Autoignition point of selected substances

Substance	Autoignition
Diethyl ether	160 °C (320 °F)
Ethanol	365 °C (689 °F)
Gasoline (Petrol)	247–280 °C (477–536 °F)
Hydrogen	535 °C (995 °F)

Is hydrogen flammable when mixed with oxygen?

Hydrogen gas is very flammable and yields explosive mixtures with air and oxygen. The explosion of the mixture of hydrogen and oxygen is quite loud.

What happens when two hydrogen and one oxygen mix?

Two hydrogen atoms bound to one oxygen atom yield water, which is electrically neutral. An electrical spark works to initiate the reaction, as does heat. But, once the reaction starts, it’s highly exothermic and goes to completion.

What’s the hottest burning substance known to man?

Thermite, a mixture of metal powder and metal oxide, is the hottest burning man-made substance in the world. It burns at temperatures of more than 2,200C, enough to burn through steel or asphalt.

Can hydrogen explode space?

Public Domain Image, source: NASA/STSI. An example of hydrogen burning is the Space Shuttle Main Engines. The External Tank of the Space Shuttle contained giant tanks of hydrogen and oxygen. Since Uranus contains effectively zero free oxygen, the hydrogen and methane in the atmosphere does not burn or explode.

Why do H2 and O2 not react at room temperature?

For a reaction between oxygen molecule and hydrogen molecule to take place the bond between the two oxygen atom in O2 and the two hydrogen atom in H2 is required to be breaked. For this process a high temperature is needed which is not possible at room temperature.
