Water can be split by electrolysis to produce hydrogen and oxygen. if you do this you find you get twice as much hydrogen as oxygen and no other products. if the two gases are combined again by adding a spark, water is produced, again with no other products (apart from a loud BANG if you have a large sample :-)

Hydrogen is extremely flammable, but it is odorless, colorless, and nearly impossible to detect using most lab instruments. It is used as a carrier gas in many instruments for that reason. There are commercial, off-the-shelf hydrogen gas detectors/alarms though that are used in battery recharging areas where hydrogen gas can accumulate.

How can you tell if hydrogen is present?
Hydrogen is very flammable, so it will ignite in contact with fire giving a pop sound
What chemical is made when hydrogen burns?
i dont know? why do you tell me :)
How can you tell if a liquid is a base?
hydrogen ions and hydroxide ions....
How can you tell if hydrogen gas has been let off?
You can use a lit splint and hold it over where you think the hydrogen is, and if you hear a loud squeaky pop sound it will prove the existence of hydrogen there. You can also test of hydrogen using a Hydrogen Leak Detector.

Density of Hydrogen?
Gaseous hydrogen has a density of 0.08988 g/cm. Liquid and solid hydrogen have a density of about 0.07 g/ccAt standard temperature and pressure (stp), hydrogen as a gas has density 0.08988 grams per litre. Hydrogen atoms have atomic mass of 1, and diatomic hydrogen molecules have molecular mass of 2. From this we can tell that hydrogen is the lightest (least dense) element in the periodic table.
What is H2H3O2?
it is the chemical formula for a "truth serum" which makes a person talkative and tell the truth
