Why is h20 not flammable?
The process of burning in this case is the oxidation of hydrogen or combination of the hydrogen and oxygen molecules. The result of the oxidation of hydrogen, its combustion product, is simply H2O or water. The reason that water (in any state) is not flammable is that it is already the product of combustion.
What is a major drawback of hydrogen fuel?
Hydrogen is a much lighter gas than gasoline which makes it difficult to store and transport. To be able to store it we need to compress it into a liquid and store it at a low temperature. The high amounts of pressure needed to store hydrogen makes it a difficult fuel to transport in large quantities.
Does pure hydrogen burn in the absence of air?
Why does hydrogen burn if there is no oxygen? Hydrogen is combustible or flammable – meaning, it can catch fire and burn easily only if there is an adequate supply of an oxidizer such as oxygen – to sustain enough thermal energy to keep the fire going after it has been ignited.
