What else can I help you with?
When hydrogen burns in air the change is chemical Give two reasons to support this assertion?
When hydrogen burns in air with H2+O2= H20
How do you distinguish between hydrogen and oxygen when burning?
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.
How does burning hydrogen not pollute the atmosphere?
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 name of a substance formed by burning hydrogen and ethanol in air?
what is the substance formad when burning both hydrogen and ethanol in the air

How hydrogen fuel engine work?
By burning the hydrogen and making water.
How do you do the hydrogen pop?
By burning Hydrogen. This isn't relevant but it is a very satisfying sound.
Why is burning matchstick is used to test hydrogen gas?

What is the common name for burning of sticks made of a carbon and hydrogen compound?
The common name for burning sticks made of a carbon and hydrogen compound is "wood fire" or simply "burning wood".
What is formed when burning hydrogen in air?
When burning hydrogen in air, water vapor is formed as a byproduct. The chemical reaction can be represented as: 2H2 + O2 -> 2H2O.
State a test for the presence of hydrogen?
The burning splint test is used to test for the presence of hydrogen. The symbol for hydrogen is H.
