Hydrogen does not support burning, instead it completely burns.
When hydrogen burns in air with H2+O2= H20
Hydrogen burns with a pale blue flame, while oxygen does not burn on its own. In a combustion reaction with hydrogen, oxygen will support the combustion process by reacting with the hydrogen to produce water vapor.
Burning hydrogen involves using heat to start combustion of hydrogen which oxidises hydrogen. The same goes for burning carbohydrates (metabolism). Oxidising hydrogen gives us H2O and, well, water isn't a pollutant.
what is the substance formad when burning both hydrogen and ethanol in the air
Yes. Burning hydrogen gas in air produces water vapor.
By burning the hydrogen and making water.
Hydrogen
Burning matchstick is used to test for hydrogen gas because hydrogen is highly flammable, so it will ignite and produce a squeaky pop sound when in contact with a flame. This is a simple and quick way to confirm the presence of hydrogen gas.
By burning Hydrogen. This isn't relevant but it is a very satisfying sound.
The common name for burning sticks made of a carbon and hydrogen compound is "wood fire" or simply "burning wood".
When burning hydrogen in air, water vapor is formed as a byproduct. The chemical reaction can be represented as: 2H2 + O2 -> 2H2O.
The product of hydrogen burning in oxygen is water (H2O). The chemical reaction between hydrogen and oxygen produces water molecules along with heat energy.
