Light a wooden splint and hold it in some of the unknown gas(which is supposedly hydrogen). If there is a loud "pop" sound, then it is hydrogen. there is a very quick and simple way to do this you have to trap the gas in side a test tube but make sure it is half full of water, trap the gas and if when you turn the test tube upside down and the water stays in the same place the bottom of the tube (which would now be top) then you have "H" HYDROGEN

To check this, you can bring a burning matchstick near the mouth of vessel from which gas bubbles are emerging. If the matchstick burns with a popping sound, then the gas is hydrogen. If not then it not hydrogen.

What is difference between hydrogen sulfide and hydrogen sulphide?
H2 is molecular hydrogen. H2S is hydrogen sulfide and is extremely toxic.
What is the state of hydrogen at room temperature?
Hydrogen is a gas at room temperature and standard pressure.
What is the state of hydrogen at 20 degrees?
Hydrogen is a gas at 20 degrees, Fahrenheit and Celsius, but it you are talking Kelvin, then it is a liquid.
What is H2S?
H2S stands for Hydrogen Sulphide.It is a gas.
Is hydrogen gas an element or a compound?
hydrogen gas is H2 so it only contains hydrogen. therefore it is an element
What is difference between hydrogen sulfide and hydrogen sulphide?
H2 is molecular hydrogen. H2S is hydrogen sulfide and is extremely toxic.
What is hydrogen and hydrogen gas?
hydrogen and hydrogen gas are same hydrogen is gas
How is the formula for hydrogen different from the formula for helium?
I am unsure what you mean by the formula for Hydrogen and Helium because both are an element, not a compound and you would generally not have a formula for an element. However, I can tell you that the difference between the formula for Hydrogen gas and Helium gas if; Hydrogen gas: H2 H-H Helium gas: He Hope this helps
What gas is formed when hydrochloric acid and magnesium are mixed?
The reaction produces hydrogen gas as will most reaction between an acid and a metal.
What is the state of hydrogen at room temperature?
Hydrogen is a gas at room temperature and standard pressure.
What gas is hydrogen?
Hydrogen gas is an extremely high explosive gas often used to make bombs...
Is hydrogen gas an expanding gas?
The question as posed has no meaning - nothing spontaneously expands. Hydrogen is, at room temperature, above its Joule-Thompson inversion point. It's hard to tell if that's what you were trying to ask or not.
Is hydrogen gas a solution?
No, hydrogen gas is a pure substance.
Is hydrogen a liquid or gas?
Hydrogen is a gas at room temperature.
Why hydrogen is called elementary gas?
Hydrogen is not an elementary gas; hydrogen has a diatomic molecule, H2.
What gas is heavier hydrogen or oxygen?
oxygen gas is heavier than hydrogen gas
How do you write the formulae for hydrogen gas oxygen gas?
Hydrogen gas is H2. Oxygen gas is O2.
