When wood burns, the hydrogen present in the wood combines with oxygen in the air to form water vapor. This reaction releases heat energy and carbon dioxide as byproducts of combustion.
No hydrogen will not burn in the absence of air unless another oxidizer is present.
That is, what they already do. No kind of fire can burn without oxygen!
Hydrogen does burn in the presence of oxygen, but it does not support combustion like traditional fuels such as gasoline or wood. This is because hydrogen gas burns with an almost invisible flame and does not produce enough heat to sustain a fire.
There is no wood that does not burn. All types of wood are combustible and can burn if exposed to high enough temperatures. Some woods may burn more slowly or with less intensity than others, but they are all capable of burning.
Yes, you can burn a piece of wood by bringing a lighted matchstick near it if the wood is dry and flammable. The heat from the matchstick can ignite the wood, causing it to catch fire and burn.
The Hydrogen will burn fiercely with a lambent blue flame and water will be produced.
If there is oxygen present it will burn (explosively)
It turns into ashes. Simple (but not if you didn't know it before though!).
All stars 'burn' hydrogen
No hydrogen will not burn in the absence of air unless another oxidizer is present.
for wood to burn you need fire
No it is not safe to burn it.
That is, what they already do. No kind of fire can burn without oxygen!
helium does not burn, hydrogen will burn in air
Wood is made of three basic elements: hydrogen, oxygen, and carbon. When it burns the oxygen and hydrogen combust and the carbon is left over. This is the quick and easy explanation.
H2O2 gives off Oxygen, O2, this gas does not burn (= react with oxygen). No H2 is let off!
Whether or not a substance can burn does not depend on it being organic. So long as it is a sufficiently reactive reducing agent, it can burn. It just so happens that most such substances on Earth are organic.
