You can prove you have made hydrogen gas because you will see bubbles rising from the soloution.You could also get a very tiny amount of the gas and hold a match to it.If it lights the it is most likely to be hydrogen gas
+++
The bubbles only prove A gas is being evolved. They do not indicate WHICH gas.
hydrogen gas is H2 so it only contains hydrogen. therefore it is an element
When hydrogen combines with nitrogen, it forms ammonia gas (NH3).
Yes, hydrogen gas is a compound. It is made up of molecules which consist of two atoms of hydrogen, an element. It just happens that the same name is used for the gas as for the element.
Potassium reacts with water to produce potassium hydroxide (KOH) and hydrogen gas (H2).
Hydrogen chloride is a compound composed of hydrogen and chlorine atoms bonded together, while hydrogen gas and chlorine gas are pure elements. Hydrogen gas is diatomic, consisting of two hydrogen atoms bonded together, while chlorine gas is diatomic, with two chlorine atoms bonded together. Hydrogen chloride is a colorless gas with a pungent odor, while hydrogen gas is colorless and odorless, and chlorine gas is a yellow-green gas with a strong odor.
If you've collected it in a flask or test tube, carefully insert a lit taper. You will get a sharp 'pop' as the Hydrogen ignites.
It has been proved by an experiment that when we pour acid on the metal then the gas will be released then light up a matchstick and up on it ,then we observe some lightening stars coming out from the matchstick ,if it happens like this is the hydrogen.
if a burning splint is brought into contact with hydrogen gas a squeaky pop sound will be produced this would prove that hydrogen is present as hydrogen is extremely flamable.
Hydrogen molecules, which is hydrogen atoms linked together.

Stars are not a gas, but they are made of gases. Our Sun it made of Helium and Hydrogen. They are a ball of gas.
The sun is made from hydrogen gas and helium gas
hydrogen gas is H2 so it only contains hydrogen. therefore it is an element
When hydrogen combines with nitrogen, it forms ammonia gas (NH3).
Hydrogen gas
Mainly hydrogen.
No, it is made of hydrogen gas.
